The 10 Best Dog Shampoo Review [Updated 2023]

Every dog owner in the world will eventually have to bathe their dogs.

There's no giving a dog a bath without using shampoo for dogs.

It doesn’t matter what size, age, or breed the dog is; you need the best dog shampoo specifically made for canines and affordable for pet owners.

Today, there are hundreds of different dog shampoo formulas for dogs with allergies, different coat types, and even medicated dog shampoos that will help to heal hot spots and other skin conditions.

TOP 10 Best Dog Shampoo Brands (reviewed below):

The research and testing process wasn’t easy, and it took weeks of researching a variety of dog shampoos to figure out which ones are the best and that fit my own pets.

Every dog should be bathed at least a few times each year, and he needs to be washed with the best dog shampoo that is made for his unique skin and fur type.

Washing your pet with human shampoo is a big no-no! Prolonged use of human shampoo can completely ruin your dog’s skin.

This is because canine skin has a different pH balance [1] than human skin.

Using human shampoo on a dog will damage his skin and coat long-term.

Although it may be a cheaper option, it’ll end up costing you big time in the long run.

Your pet’s skin and coat are his first line of defense against germs and bacteria.

Your dog’s overall health and well-being will suffer if his skin isn't healthy.

Maintaining your dog's skin and coat are also essential for your dog’s general comfort.

Matted hair and itchy skin can both cause a lot of physical pain for your Fido.

Skin and Coat

Although dog grooming consists of caring for your pet’s entire outer body, his skin, and coat are the largest part of that.

The most essential thing you can do to promote skin and coat health is to bathe your dog regularly to keep him clean.

Oils, dirt, and bacteria build up in your pet’s fur, and a traditional bath with dog shampoo and water is the only way to really get him clean.

Waterless shampoos [2] can be used in between bathing, but there is nothing that you can do to help your pet more than give him a traditional bath.

If Earthbath All-Natural Oatmeal & Aloe Dog Shampoo isn't available, I recommend that you look at a similar product – 4-Legger Certified Organic All-Natural Dog Shampoo.

This top-quality dog shampoo is made with organic oils, organic Aloe Vera, essential oils, and rosemary extract as a preservative.

Not only is this dog shampoo eco-friendly, but it’s mild on your dog’s skin and is also made in the United States.

This pet shampoo is safe, gentle, and non-toxic.

It foams nicely and rinses clean.

4-Legger dog shampoo is specifically formulated to clean, deodorize, moisturize, and condition your dog’s skin and coat without stripping the natural oils or washing off existing flea and tick treatments.

What you should know before buying

Before buying any of the best dog shampoo products on this list, you must know your dog's needs.

First, consider his age. This is really only necessary if your dog is under 1 year.

Some shampoos cannot be used on puppies under 8 weeks, 12 weeks, 6 months, or even a year old.

The chemicals in these shampoos may be too harsh for a young dog’s skin.

You’ll also need to consider your dog’s skin and hair type. Is his skin greasy or dry? Does he have long hair or short hair?

Is it curly or straight? The answers to these questions will help you decide which product to buy.

Be sure to get a shampoo that is specifically formulated for your dog’s skin and coat type.

If your pup has any skin conditions [8] or medical issues affecting his skin or coat, consult your vet before buying anything.

These conditions can be caused by something as simple as feeding your pet the wrong dog food.

The chemicals in the doggy shampoo you buy may irritate your dog’s skin more and cause even more problems.

Medicated dog shampoos are all designed to treat different conditions, so do your research and ask your vet if you have any questions.

I also need to take a minute to get on my soapbox and ask you to think about the importance of selecting safe products for your dog.

As I mentioned earlier, human shampoos are not pH-balanced to help a dog's skin.

I know they are cheaper, but in this case, you’ll get what you pay for.

Dog Shampoo Quality Counts

Dog shampoos aren’t all the same quality, either.

Spending a little more on a bottle of pet shampoo will get you a much higher quality product.

All-natural products are a great choice, considering you’re putting the shampoo directly onto your dog’s skin.

Shampoos made with harsh and toxic chemicals can leach through your pet’s skin and harm his body greatly.

Consider spending a few more dollars and getting a product that is 100 percent safe for your pet and better for the environment.

I'm always looking for ways to save money, and sometimes, that means spending a little more upfront and reaping the savings later.

A bottle of shampoo goes a long way, so buying a better quality dog shampoo will probably only increase your family budget by about $10-$20 per year.

How I chose these best dog shampoos

This was quite a bit easier than some of the other Top 10 lists I’ve created.

I was shocked (more like horrified) at many of the pet shampoo products on the market.

So many dog shampoos are filled with toxins and harmful chemicals.

What’s worse is that you can find a laundry list of consumer complaints about most of these products with a quick internet search.

I’m not naive enough to think that there are products out there with 100 percent perfect reviews from customers.

I know that no matter what product I’m researching, there is going to be someone who doesn’t like it. That’s the nature of the beast in the review industry.

There were so many pet shampoos that had hundreds of negative reviews.

Consumers were saying horrible things like the shampoos dried out their pet’s skin, they gave their dog a rash, and some pet parents even posted pictures of the sores that their dog supposedly developed after using certain products.

I figured out pretty quickly that the options for high-quality, safe dog shampoos were not numerous.

Then, I began whittling down the list and went to the consumer reviews after coming up with my top 20.

I needed to know that these products were tested and proven to work by the manufacturer, and pet parents found that they worked well in real-life situations too.

My picks for the ten best dog shampoos needed to appeal to pet parents, professional groomers, and veterinarians.

I needed to make sure that the products I recommended were healthy and safe for pets while also doing exactly what the manufacturer said they would do.

How I researched and evaluated each dog shampoo

I performed all my research online. I read information from consumer reviews, manufacturers' websites, and articles and blogs from experts in the pet grooming industry.

Then, I started by finding out what qualities were needed in a dog shampoo.

What does a dog need from their shampoo? First and foremost, they need it to be safe.

My search for safe and healthy shampoos brought me to a list of all-natural, hypoallergenic, and eco-friendly products.

But did these shampoos actually work, and were they as safe and healthy for canines as their manufacturers made them out to be?

Unfortunately, in some of these cases, the answer was no.

After completing all the pet industry research, I had my list narrowed down quite a lot.

That’s when I dove into consumer reviews. What did pet parents think about these products? Were they effective?

Did they have a pleasant fragrance? Were they affordable?

I needed to know what everyday pet parents thought about these products when they tested them out in the real world.

Every dog is different, and I needed to know that the products I chose would work for a wide range of dogs, not just a select few.

What to look forward to

In today’s economy, everyone is looking for ways to save money.

One of the easiest ways to cut your pet care costs is to groom your dog at home.

The pet industry is beginning to see more at-home groomers, and that means there need to be more products directed toward that market.

We’ve already seen a drastic increase in the number of at-home grooming products available in recent years, but I’ve got a good feeling that we’ll see that number continue to rise.

Researchers are doing almost as much research on canines as they are on humans.

They realize that dogs need specialized products just like we do.

Every dog is different; the same can be said for every dog’s coat.

As more research is done about skin conditions in canines and all the types of canine coats, we’ll see new products hitting store shelves geared toward those dogs’ individual needs.

Top 10 Best Dog Shampoo Brands

Earthbath All-Natural Oatmeal & Aloe Dog Shampoo 

This is my number one pick for my dogs. As its name suggests, this is an all-natural pet shampoo. The main perk is that you don't have to worry about toxic chemicals affecting your dog’s skin. This product is 100 percent biodegradable and cruelty-free.

This all-natural dog shampoo is also soap-free and smells great.

It is a safe, effective, gentle shampoo for dogs that is affordable and works well.

After a lot of research looking for the best shampoo for dogs that I can use with my pooch, after bathing my three dogs and sifting through information from pet care professionals, I have come up with a list of what I believe are the ten best dog shampoo products.

Our Earthbath All-Natural Oatmeal & Aloe Dog Shampoo Review

Now more than ever, pet parents need to pay attention to the dog products that they are using on their pets.

More and more recalls are happening all the time, and manufacturers seem to be more concerned with making a dollar than the safety of the products that they are creating.

It’s scary to think that these dog supplies we buy for our dogs could actually do more harm than good.

In my opinion, you don't have to worry about causing harm to your dog's skit and coat with Earthbath All-Natural Oatmeal & Aloe Dog Shampoo.

This is possibly the safest dog shampoo you can use to wash your dog’s skin and fur.

When I first started researching this product, I read it is soap-free.

Soap-free? Why would a shampoo be soap-free?

Isn’t the whole point of shampoos for dogs to contain soap for cleaning hair and skin? Not really, and here's why.

Believe it or not, your dog’s skin is more sensitive than a baby’s, and Earthbath pet shampoo is pH balanced to be milder on Fido’s skin than soap.

Soap can dry out canine skin and leave residue in your dog’s fur. This is a major cause of dandruff and itching in dogs [3].

Soap is also more likely to wash off any type of topical treatments that you may use on your dog, including treatments for fleas and ticks.

Earthbath Dog Products: What's in Them?

Earthbath dog products are phthalate-free and paraben-free.

Phthalates are molecules that are found in many fragrances, and they are linked to birth defects.

Parabens are a group of chemicals that are used as preservatives in many products, including human and pet shampoos.

In 1998, the United States Environmental Protection Agency (EPA) released a report that stated parabens such as butyl, methyl, ethyl, and propyl varieties cause “estrogenic activity.”

That means that they may imitate hormones found in the body and have a negative effect on the endocrine system, and should be avoided in dog shampoos as well [4].

Dry, itchy skin is a big problem for many dogs.

My pick of the best dog shampoo is specifically formulated with oatmeal and aloe to relieve itching and address the needs of pets with dry skin, as other experts and reviewers have already confirmed.

It's also the best-smelling dog shampoo I have ever tried.

The combination of oatmeal and aloe allow this dog shampoo to combat skin irritation, re-moisturize sensitive, dry skin, and promote healing.

Not all pet shampoos are safe for puppies, but you can use Earthbath's dog shampoo on all dogs over 6 weeks old.

It won’t wash off topical flea treatments, which we use on our dogs to fend off disease-carrying pests.

I’ve been using this dog shampoo on both of our dogs for about six months, and we've never had any trouble with their flea and tick treatments being removed.

They lasted as long as they always do, so I know this pet shampoo did not hinder their effectiveness.

The ingredients in this best dog shampoo include purified water, colloidal oatmeal (3%), renewable plant-derived and coconut0based cleansers, aloe vera, vitamins A, B, D, and E, glycerin, allantoin, food-grade extracts of vanilla and almond (which makes it one of the best-smelling dog shampoos), and a natural preservative.

It does not contain gluten, soap, DEA parabens, SLS/SLES [5], synthetic dyes, perfumes, or enzymes.

Earthbath's All-Natural dog shampoo is 100 percent biodegradable.

Who else likes it?

It would be easier to tell you who doesn’t like it! This product is veterinarian-recommended. How do I know that? Because our own vet recommended it to us.

There are also tons of product reviews online from pet parents who say that their veterinarian recommended Earthbath All-Natural Aloe & Oatmeal Dog Shampoo as well.

Consumers also highly recommended this dog shampoo. There are over 1,100 reviews on Amazon, and it has a 4.6-star rating.

You’ll also find reviews on many other websites as well, and if you do a quick search on YouTube, you’ll find hundreds of videos of pet owners recommending this dog shampoo.

Top 3 most helpful customer reviews. Read all Amazon reviews here.

Amazon Customer: Very Pleased!_ (September 9, 2011. Read full review.) “I was a bit skeptical to try this on my Australian cattle dog after countless attempts with different shampoos and very little success. I was stuck debating between the Oatmeal & Aloe vs. Tea Tree and Aloe. I decided to go for tea tree, based on her ongoing skin issues. After the first few washings, I started to notice dramatic results with her obsessive scratching, which I feel was either fungal or allergy related, if not a mix of the two…”

Gina Bird: The VERY Best Shampoo for your loved one!!!_ (February 18, 2008. Read full review.) “Earthbath Oatmeal & Aloe Pet Shampoo is the best and most gentle way to bath your loved one. It gives you all the benefits of being all natural, soap free with oatmeal and aloe that Vet's recommend for sensitive skins. Plus, it leaves your loved one fresh, clean and very, very SOFT! Fur feels like it did when my dog was a puppy!…”

lola: great for skin problems_ (October 14, 2007. Read full review.) “I started using this a long time ago on one of our dogs who had oily, but very itchy skin from seasonal allergies. we tried dozens of shampoos that were supposed to help her itchy skin, but none of them did, except for this one. it cleansed all the oil off her skin, but didn't leave it dry, and for the first time in her life wasn't constantly itching her skin!…”

Flaws but not deal breakers

One thing you may find while researching this product is some consumers with concerns about tea tree oil and its effects on dogs.

Yes, 100% tea tree oil is indeed toxic to dogs.

However, rest assured that All-Natural Oatmeal & Aloe Shampoo from Earthbath DOES NOT CONTAIN TEA TREE OIL.

As you can see from the ingredients I listed above, no tea tree oil is used to make this best dog shampoo.

The company does use tea tree oil in some of its products, but with the proper research, you will see that when properly diluted, tea tree oil is actually very beneficial for dogs.

According to the Pet Poison Helpline [11], products that contain tea tree oil in concentrations less than 1-2% are generally considered non-toxic to dogs if used according to labeled directions.

Many dog products contain tea tree oil. It has been shown to treat bacterial and fungal skin infections and external parasites like mange and fleas.

Many products containing tea tree oil are recommended by holistic veterinarians and other pet care specialists.

Again, although some Earthbath products do, this shampoo does not contain tea tree oil, so there is no cause for alarm.

Runner-up: Best Deshedding Dog Shampoo

Excessive shedding in dogs is another common problem in many pet-owning households. For dog owners who may not need a soothing shampoo for dogs like the Earthbath, you may be interested in the best deshedding dog shampoo.

FURminator is known for its deshedding grooming tools, but did you know they’ve also created an effective deshedding dog shampoo?

Best shampoo for dogs should be safe for the pet and also give the owner what they want for the price.

If you’ve got a dog that sheds a lot, why not try removing some of that unwanted hair with an anti-shedding dog shampoo?

The blend of ingredients in FURminator deShedding Ultra Premium Shampoo helps reduce excess loose hair by releasing the undercoat during bathing.

This shampoo contains the following ingredients: water, mild surfactants, omega 3 and 6 fatty acids from cranberry, sunflower, and safflower seed oils, extracts of calendula, papaya leaf, chamomile, Malva flower, blueberry, aloe vera, and kava vitamin E, vegetable protein extract, hydrolyzed wheat and oat proteins, fragrance, a preservative, and salt.

This shampoo has no parabens, artificial colors, or chemical dyes.

The company specifies that this shampoo for dogs should be used monthly in order to get the most effective hair removal.

They also say that it is to be used in the FURminator deshedding regiment, meaning that this product helps to loosen the dead hair from your dog’s coat, but only some of that hair is washed away during the dog bathing process.

Some of the loosened dog hair will still be in your pet’s coat, and you’ll need to brush him to remove that hair.

De-shedding Shampoo Is Not a Cure-All

You’ll find that after you use a product like this, you’ll be able to brush a lot of hair off your dog.

Please note that deshedding shampoo for dogs will not be a “cure-all” formula to allow you to avoid grooming your pet and using dog grooming tools.

Pet owners will still need to brush their dogs.

This second-best shampoo for dogs simply helps to remove some of the loose, dead hair that is entangled in your pet’s coat.

It’s a little deceptive, as most pet parents believe that deshedding shampoo for dogs should remove the hair completely, but that isn’t exactly the case.

It will help reduce shedding, but you’ll also have to do a little work.

Compared to brushing your dog after a bath with a traditional dog shampoo, FURminator deShedding Shampoo will help to release a lot more fur.

This best dog shampoo is made in the United States, and aside from loosening dead hair, it also promotes healthy skin and coats in dogs and leaves your canine looking great and smelling clean.

It's another great option for the best-smelling dog shampoo.

Other Picks

Zymox Enzymatic Shampoo

Itch relief is taken to a new level with Zymox Enzymatic Shampoo. This best dog shampoo utilizes the LP3 Enzyme system to relieve chronic itching. Enzymes are proteins that occur naturally and increase the rate of chemical reactions.

They are a natural defense against harmful microbes.

These enzymes will not irritate your dog’s raw or sensitive skin. They are safe and non-toxic for people, pets, and the environment.

Bacteria cannot develop resistance to enzymes, thus, this dog shampoo with enzymes is ideal for dogs with chronic issues.

The patented LP3 Enzyme System combines different enzymes, each with a specific job, which work together to inhibit, split, and destroy bacteria, fungi, and some viruses.

This shampoo is antibacterial as well as anti-fungal.

The greatest thing about enzymes is that they only target invading single-cell organisms – the healthy cells are completely unaffected.

This shampoo does not contain harsh detergents, steroids, petroleum bi-products, or toxic chemicals.

It’s gentle enough for puppies and has a very mild fragrance.

This dog shampoo from Zymox even aids in the healing of infections. You’ll find countless reviews from pet parents who have used this shampoo to treat their pet’s skin conditions.

Buddy Wash Lavender & Mint

Buddy Wash Lavender & Mint is another best dog shampoo product that made my list. This is a 2-in-1 product that shampoos and conditions your dog’s skin and coat. This is another all-natural product that you’ll know is safe to use on your dog. It’s also made with botanical extracts of lavender and mint (hence the name) to provide a calming effect for pets with grooming anxiety.

Buddy Wash is made by a company called Cloud Star.

Pet owners really raved about the lather that this shampoo offers.

They say it offers a rich, fluffy lather that easily rinses cleanly off your pet.

This product is made with ingredients like wheat protein, sage, rosemary, and vitamins C and E that won’t irritate or dry out your dog’s skin or cause any additional dermatological issues.

This shampoo does contain tea tree oil, which as I mentioned earlier is completely harmless to your pet when diluted.

This is a coconut-based shampoo that utilizes aloe vera gel to soothe your dog’s skin and provide relief from itching.

Natural fragrances from chamomile, mint, lavender, and rosemary leave your dog smelling great without any harsh fragrances or harmful perfumes.

The wheat protein also acts as a natural deodorizing agent to keep your Fido fresh between baths.

In fact, it has some great healing powers when diluted. It calms itchy skin that is irritated by flea bites, pollen, or seasonal allergies.

There is also vitamin E in this shampoo, which protects the skin cells from sun damage and pollution.

Wahl Dry Skin & Itch Relief Pet Shampoo for Dogs

Another excellent choice for the best dog shampoo is Wahl Dry Skin & Itch Relief Pet Shampoo for Dogs. This all-natural shampoo is formulated for dogs and cats. This is another shampoo that is made with oatmeal and aloe to soothe the skin.

Its scent smells similar to baby wipes, which many consumers enjoy.

This shampoo is specially formulated to restore the natural oils in your pet’s skin and smooth his coat.

It is made with oat extract to nurture and restore softness and manageability to your dog’s fur.

It also contains shea butter, which infuses the hair with extra moisture and softness.

All-natural ingredients mean that it has no harmful irritants, additives, or preservatives. Wahl products are made in the U.S.A.

The ingredients found in this dog shampoo are water, a non-ionic/amphoteric blend, Cocamidopropyl betaine, glycerin, lanolin, oat extract, aloe extract, glycol distearate, fragrance, and a preservative.

Many pet parents that purchased this product say they saw results in their dog’s skin and coat after just one wash.

Top Performance Shed Patrol 

Odor is just as big of a problem with canines as itchy skin. Some dogs bring it on themselves by rolling in things or getting into places they aren’t supposed to go. Other dogs just have their own natural funk.

If you’ve got a dog with itchy skin, a shedding problem, and a stinky smell, you’ll need a really good dog shampoo.

Top Performance Shed Patrol is the best dog shampoo to handle all these problems.

As its name suggests, this is a deshedding shampoo that will help to control excess shedding.

It also contains an odor-eliminating complex that destroys strong odors on contact and leaves your dog with a refreshing apricot scent.

Top Performance offers pet parents a shampoo that will clean their pet and help reduce shedding, and it won’t irritate their skin either.

Consumers were really happy with this product.

A lot of pet parents with dogs that shed excessively, like Huskies and Newfoundlands, commented on the large amount of hair that this shampoo helped to remove.

Obviously, with a dog that sheds like a husky, you’re never going to be rid of all the excess hair, but this product will help you so you don’t have to brush them as often, and you won’t have as much hair around your home or on your furniture.

A pick for fleas and ticks

My final pick is for a problem we’ve all had, and chances are we’ll be dealing with it again soon enough.

Fleas and ticks [12] are a thorn in the side of pet parents everywhere.

They spread diseases, and they cause your dog a lot of discomfort.

Preventative measures, including flea collars, topical treatments, and oral flea and tick preventative medications, can do wonders at keeping the little pest away, but what do you do if your dog still ends up contracting them?

Flea and tick shampoos are the first lines of defense for most dog owners when it comes to dealing with these nuisances. Although you’ll still need to treat your home, getting the fleas off your dog is the first step.

The best dog shampoo for ridding your Fido of these annoying little vermin is the Wondercide Shampoo Bar for Dogs.

I know what you’re thinking…”A shampoo bar for a dog?” Yes.

Believe it or not, you can actually bathe your dog faster with a bar than you can with traditional shampoo.

Easy Bar Application

You don’t have to waste time putting the shampoo on your pet; all you have to do is hold the bar and rub it all over your pet’s body.

You won’t have to try and spread the shampoo all around.

It’s easy when the bar is in your hand, and you can rub it anywhere on your pet that needs a little extra lather.

Speaking of lather, you’ll be surprised at the rich lather that this bar creates.

It’s better than many traditional dog shampoos.

This shampoo bar from Wondercide uses all organic ingredients. It is also 100 percent biodegradable.

Neem leaf extract, organic neem oil, and aloe vera kill and repel insects.

The entire list of ingredients includes coconut oil, palm oil, shea butter, castor oil, neem oil, citronella oil, geranium oil, neem leaf extract, aloe vera, vitamin E, and honey.

The citronella and geranium oils provide the ultimate protection from fleas and ticks [13] without the harmful chemicals found in many other preventative products.

The secret ingredient in the Wondercide Flea & Tick Natural Shampoo Bar is the neem oil.

It is naturally antibacterial and antifungal.

Both of these properties help to address the issues behind itchy skin. It can be used to treat dry skin, itchy skin, skin diseases, sores, and insect bites [14]. It’s even been used to treat skin ulcers, eczema, and ringworm.

Best Dog Shampoo for Puppies

For the same reasons that you shouldn’t wash your dog with human shampoo, you also shouldn’t wash your puppy with shampoo that is made for adult dogs. Your puppy's young skin is just as sensitive as the skin of a human baby.

The harsh chemicals, perfumes, and dyes in adult dog shampoo can irritate a puppy's delicate skin.

When you're looking to bathe a young dog, you must get the best dog shampoo for puppies.

Products like Burt’s Bees Tearless Puppy Shampoo are designed to get your puppy clean and completely washed out of his fur without hurting any of his skin.

These puppy shampoos do not leave a residue that would irritate your pup’s skin.

This product is also tearless, which is an ideal quality to have in the best puppy shampoo.

It’s hard to keep a young dog still while you’re trying to wash him, and he will inevitably get shampoo in his eyes at some point.

Special Puppy Shampoo

This dog shampoo for a puppy is made with buttermilk to help soothe and soften your canine's skin. It contains no sulfates or colorants, and it is a cruelty-free product.

Burt’s Bees makes this puppy shampoo with water, coco betaine, coco glucoside, glyceryl oleate, disodium cocoyl glutamate, vegetable glycerin, xanthan gum, honey, beeswax, buttermilk powder, potassium sorbate, and sodium benzoate.

That ingredient list of Burt's Bees Puppy Shampoo may not sound natural to you, but all these ingredients have been confirmed not to be harmful to a puppy.

Additionally, I've done a quick Google search about the dog shampoo ingredients [6], and I found out that coco betaine, coco glucoside, vegetable glycerin, and disodium cocoyl glutamate are all derived from coconut oil, as you may expect.

Glyceryl oleate is produced from oil containing high concentrations of oleic acid, including peanut oil, olive oil, tea seed oil, or pecan oil. Xanthan gum is also plant-based.

It is a thickening and stabilizing agent. Potassium sorbate and sodium benzoate are both natural preservatives.

Best Medicated Dog Shampoo

Some dogs require treatment of their coat or skin with a medicated dog shampoo.

A top-quality medicated shampoo like Synergy Labs Veterinary Medicated Shampoo can treat skin scaling caused by Seborrhea, treat fungal and bacterial skin infections, and relieve mange and other parasitic infections in dogs.

These best-medicated dog shampoos can also help get rid of inflamed scalp, waxy and greasy skin, skin rashes, and scaly skin (similar to dandruff).

Synergy Labs Veterinary Formula Clinical Care Antiparasitic & Antiseborrheic Medicated Shampoo also contains allantoin and colloidal oatmeal, which promote healing and hydrate the skin.

Synergy Labs' best dog shampoo with medications is paraben, dye, and soap-free.

It combines coal tar, salicylic, and micronized sulfur in a powerful medicated shampoo that is proven to treat a number of skin conditions, including Seborrheic Dermatitis [7].

Seborrheic Dermatitis is a skin disorder that can be the result of yeast or bacterial infections, and it can also be genetic.

This disorder is common in canines.

Bath Your Dog More Often

When using a medicated shampoo for dogs like this one from Synergy Labs, you’ll need to bathe your dog two or three times a week until the symptoms clear up.

Then, you can use it less frequently as a preventative measure.

Before using any type of medicated dog shampoo, you should check with your veterinarian to ensure that it will be effective for your dog's skin condition(s).

Although Synergy Labs Veterinary Dog Shampoo is often recommended by vets for dogs that require assistance from a medicated dog shampoo.

Best Dog Shampoo for Itchy Skin

My number one pick for the best dog shampoo is a great option for dogs with itchy skin.

It cleans, deodorizes, and helps to soothe your canine's skin and coat and is probably the best-smelling dog shampoo there is.

However, if you’re unsure about that product or you're looking specifically for a shampoo to help your itching dog, Oatmeal or Argan Shampoo for Allergy Relief and Shedding Dog is by far the best choice.

Many experts and dog owners have agreed this is one of the best dog shampoos for itchy skin.

Pet skincare experts in the company’s state-of-the-art laboratory scientifically developed its potent anti-itch formula.

The ingredients include oatmeal and Aloe Vera extracts, rinsing and moisturizing agents, lauryl betaine (a synthetic, vegetable-derived liquid that is used as a hair conditioner), salt, coconut fragrance, and purified water.

Shampoo That Leaves a Dog's Coat Shiny

Consumers love the coconut fragrance and rave about this shampoo's ability to leave your dog’s coat shiny and radiant.

Because this shampoo for dogs works at the skin level, it moisturizes and conditions the skin, which gives your canine's coat a gorgeous luster.

The health of your dog’s skin is directly related to the health of his coat. This doggy shampoo from Paws and Pals helps reduce the irritation that causes dog itching and scratching.

Bear in mind that Oatmeal and Aloe Vera Shampoo is not a medicated shampoo like the one from Synergy Labs, so if your dog has an underlying infection or condition, like dog skin allergies, that is causing the itching, this pet shampoo will not help.

If your canine is constantly scratching, it is best to have his skin examined by a veterinarian before using any type of dog shampoo to bathe him.

If you choose the wrong shampoo for the dog, it could end up irritating his skin even more and making the situation worse.

The Bottom Line Best Dog Shampoo

Pet shampoos for dogs come in many varieties based on your pet's skin and coat type. If you need something specific like an itch relief, a medicated dog shampoo, or a shampoo for dogs that shed excessively, look for that specific type among the best dog shampoos.

If you're looking for a general-purpose dog shampoo to have on hand for a canine with average skin and no sensitivities or allergies, Earthbath All-Natural Oatmeal & Aloe Dog Shampoo is a great choice.

Now, let's talk more about the details of how these choices for the best shampoo for dogs have been made and what other alternatives are there in case my top five picks aren't suitable.

Answering Questions about Best Dog Shampoo

What do I know about dog shampoo?

Frankly, I’ve learned more about dog shampoo in the last two weeks than I ever knew.

However, when you think about it, many of the warnings about dog shampoo are the same as many other pet products.

Selecting a product that is as natural as possible, spending a little extra money to get a better quality product, and making sure that you buy a product that is made specifically for your dog are words of advice that you should follow when making any kind of purchase for your canine companion.

Being a dog owner for more than 20 years has given me the opportunity to use many different pet shampoos.

I’ve used store-brand dog shampoo and more expensive all-natural shampoo, and you can definitely tell a big difference in your pet’s coat, depending on which you use.

Also, I have used medicated shampoo before, but it was only for a short period of time when one of our boxers had a rash.

I never had a dog with a chronic skin condition that required long-term use of a medicated shampoo, but I can say that it sure cleared that rash up pretty quickly.

Also, my experience working for Top Dog Tips over the last year has helped me acquire much knowledge about pet products.

I’ve written articles and done research on everything from dog beds to grooming products.

I’ve read thousands of articles and customer reviews and gotten a lot of information about the different kinds of pet shampoos available [9].

It certainly doesn’t make me an expert, but it does make me knowledgeable on the subject.

Can dog shampoos improve my dog’s health?

As you can tell from all the information in this article so far, the best dog shampoo can improve your pet’s health.

The right shampoo can promote and maintain your dog’s skin and coat health.

Medicated shampoos can clear up many different skin issues, from bacteria and fungus to rashes and dry skin.

Your dog’s fur and skin are his first line of defense against germs and bacteria.

By bathing him regularly, you’re keeping that defense clean and strong so it can protect him.

Not only can the best dog shampoo improve your dog’s physical health, but it can also improve his mental health too. Mats and tangles can cause your pet a lot of pain and discomfort. By taking care of his coat, you’ll be saving him a lot of stress and agony.

Who should buy dog shampoo?

I don’t see pet shampoo as an option that some people need, and others do not. Every pet parent should always have a bottle of dog shampoo on hand.

Even if you take your dog to the groomer, you still may need to bathe him at home sometimes.

Dogs are unpredictable by nature; they roll in things, enjoy playing in the mud, and are very messy creatures.

Having a bottle of shampoo on hand for all those unexpected messes is a wise decision.

If not, you’ll have to run to the store last minute while your Fido is tied outside, smelling like the fertilizer from your garden.

Your local store may not have the right kind of shampoo for your pet, and you’ll have to buy something else that may irritate your dog’s skin.

Chances are you’d probably head to your shower first anyway to try to find something that will make Fido smell better, and we already know human shampoo is a bad choice for dogs.

On average, a bottle of the best dog shampoo will cost you $10-$20.

Isn’t it worth $20 to know you’ll be able to clean your pet with a safe and effective shampoo when needed?

The cost of professional grooming can add up, and you’d save yourself a lot of money [10] if you bathed your dog yourself sometimes.

Instead of taking your pet to the groomer once a month, you could take him every other month and bathe him at home on the off months.

That alone would cut your dog grooming expenses in half!

Best Dog Shampoo: Final Thoughts

Every dog needs to be bathed at some point.

Whether you do your own grooming or your dog has a tendency to get dirty, you should always have a bottle of the best dog shampoo on hand.

Remember that shampoos are as unique as your pet. There are many different formulas for different ages, coat types, and skin types.

If your dog has any sensitivities, you should be sure to talk to your veterinarian before selecting a shampoo.

They will be able to help you select the best dog shampoo for your pet’s individual needs. You may also seek advice from your groomer.

Chances are, they probably know your dog’s skin and coat better than your veterinarian.

Parabens, phthalates, and other harsh chemicals may not affect your dog’s skin immediately, but they will take a toll over time.

Spending a few dollars extra on a high-quality shampoo with natural, soothing ingredients is a much better choice.

Even if your dog has excellent skin that isn’t sensitive to anything, the chemicals in poor-quality pet shampoos can leach into their system over time and cause a lot of serious health issues.
