Too Expensive!
Flavor Name: Peanut Butter with Cranberry
Our two standard poodles love these treats but they are too expensive. They're very small and at over a dollar a piece I just can't justify it.

Where's my Dog treats
Flavor Name: Peanut Butter with Cranberry
I never received, no photo of where it was delivered. Update: Driver dropped off at the wrong address. My neighbor was kind enough to bring to my house. These treats are one of my dogs favorite treats. Sometimes they are a little hard but are mostly soft enough for my older dog.
