Meets dog and cat approval 100%
Size: 3 Ounce (Pack of 1)
Don't leave the bag out. Even if it is closed. My cat tore it open and shared it with both dogs nearly depleting the big bag in one day

My dog loves these!
Size: 5.75 Ounce (Pack of 1)
My dog loves these! I add a few pieces to his food to entice him to eat his meals. He loves the chicken! I appreciate that it is just chicken, and I am not giving my dog a bunch of filler.

Good Treats
Size: 3 Ounce (Pack of 1)
One ingredient healthy treats. I have bought them several times and my dog loves them. Only complaint is there were a lot of broken pieces that were more like crumbs.

These are my small dogs favorites! I love to put these in the dog puzzles for some good boredom busters for them. Clean treats with no preservatives!
