It's a treat inside of a treat! These Pro Puffs are tasty little treat puffs filled with nutritional treats and probiotics! Forget tasting the rainbow these things smell good enough for humans to eat! We love them. Our dogs love them and they are an amazing treat to use for dog training. We also like to designate this treat to potty training only with a lot of our dog training clients. It is a very very good treat to use for teaching behaviors to your dog!
