Our dog loves them!
Flavor Name: Chicken, Flavor Name: Chicken
We are very impressed with these Gaines Family Farmstead Chicken chips! Our dog is picky and she absolutely loves them! She just turned 13 so we are trying to give her the best and healthiest. These chicken chips have only one ingredient so they are perfect! We will be ordering again!

Please be.careful
Flavor Name: Chicken
Love the Gaines Family treats, but this one made my 22lb dog deathly ill for 5 days. We feared we would lose him as nothing would stop the diarrhea and retching. He couldn’t even make it through the night without multiple trips outdoors.

Dogs can't get enough
Flavor Name: Chicken
If I let them, my dogs would eat every single piece in one setting. My Chihuahua even dances for them. Will definitely buy again.
