I rescued two pit bulls about 2 years ago and they are loving dogs and very protective. We could not walk down the street without them trying to go after a person or dog. If someone came to the door they wouldn’t stop barking and had to be put in their crate. Sam Ivy came to my home and for almost an hour explained and answered questions regarding the training. Unlike other so-called trainers, he gave his word that the trainer would not leave after a certain time. True to his word, after 4 weeks of twice a week training they can walk down the street without incident. When someone comes to the door, they bark and they are given a command without yelling and they stop barking and go to a designated spot and stay here until they are released. I never thought it was possible but I was wrong. Claudia who is a tiny lady who knows her stuff and I would recommend her for any problem dog.
