Popcorn isn't necessarily bad for your dog, but if you're looking for a healthier alternative Yaky Charms by the Himalayan Dog Chew company is a great choice. It's microwavable and only made with four all-natural ingredients.
Yaky Charms are made using techniques by the people of the Himalayas which are derived from an ancient recipe to convert milk into a hard cheese. This same method is practiced at the company's farm in Washington State.
The unique dog treats are made without any preservatives or additives. They are handmade in the USA and created using only lime juice, salt, and yak and cow milk. The crude protein minimum in these treats is 73.4%.
