My picky dog loves them.
Size: 3.5 Ounce (Pack of 2), Style: Chicken Chips, Size: 3.5 Ounce (Pack of 2), Style: Chicken Chips
I try to give my dog, whom I love so much, the healthies food and treats that i can. She is so very picky and it's difficult to find things she likes. She loves these treats and expectes one every morning. She litterally waites by the pantry door for one. The are healthy Human grate chicken chips. Makes me feel better about giving her a treat. I would Highly recommend.
