Chik'n Chips are our dog's favorite snack! Beau is absolutely crazy about them. If you really want him to do something, just tell him to "Sit" and give him a Chik'n Chip. Or show him one and ask him "What do you do?".

The dogs love it!
Size: 1 Pound (Pack of 1)
They look like slices of hot dogs, and they're a bit hit with my pups. Even my picky eater loves them! They're large enough to be satisfying and small enough that overfeeding the dogs is not an issue.

My dogs absolutely love this treat.
Size: 8 Ounce (Pack of 1)
I have very picky dogs so I usually would start off with something small to give to my dogs. Sort of like a taste test. Case in point, I bought a small bag to test. Surprisingly, both of my dogs love this treat so I continued to purchase this item. These chips are pretty expensive so I try to buy them once a month on a subscription. Sometimes I end up buying more within the month because my dogs gobble these up like its their last meal. But again, these chips are pretty expensive but my dogs really love them.
