Q: This is not jerky, this is processed, hard like a rock, very greasy and stale smelling stripe of something that you can't break into anything smaller than 2 inches long and that certainly is not the size of a training treat! The dogs- who will eat anything- were not impressed, it was hard to chew, and it sounded like they were crunching rocks, where is a zero star button?
A:
Negative
