Wow… let’s just say I never thought I could get any of my dogs to stop being so reactive….. and looks at this amazingness…. Hato and Teddy walking by and not reacting other than sniffs…. this is amazing all done with positive reinforcement, or clicker training, best money I have spent on my dogs. She is amazing with the puppies and helping us teach them a better way. Went to almost putting my pup down because we feared of bites, to having this loving puppy who just wants to please. All the dogs have picked up on the difference and the family of furry kids is now happy and tails are wagging. Thank you so much, Debra.
