My American Bulldog loves these treats! We've used them to train him to learn new tricks, and they are working great. He's learned to roll over, stand up, and is also learning how to catch!
My dog is also very picky about treats and can be rude about it. Lol. (A tech tried to give him a milkbone and he turned his head, rejecting it. The tech tried again later and my rude dog chewed it up and spit it out in the floor.) So, if you're having trouble finding a treat your dog likes, try these. They aren't too expensive so if your dog doesn't like them, you haven't wasted much money.
