I just wanted to give you a quick update on things...My parents were here for about two weeks and they noticed a positive difference in Roscoe! He wasn't jumping up as much and they noticed that he seemed to be calmer and happier overall. We had a male friend stop by this evening to drop something off and we were so impressed with Roscoe's behavior! We made him sit and wait on the rug and when the friend walked through the door, Roscoe did growl at first, but we were able to quickly correct his behavior by using the techniques that you showed us. After about a minute of lying on the rug, Roscoe really wanted to say hello to this friend and he approached the man very calmly, wagging his tail and allowing the person to pet him. Nothing like the way he used to react! We were so impressed and this gave us so much confidence in our ability to show Roscoe who is the leader of the pack. This was the first time we have had a guest (other than family) in our home since you were here and I am so pleased with the way things turned out. We also had a very positive experience when we recently took Roscoe to the vet. During our previous visits to the vet, they would have to put a muzzle on Roscoe because of his aggressive behavior. Roscoe was much calmer and seemed more trusting of me and my husband and the staff at the clinic. The vet noticed a positive difference in Roscoe's behavior and we didn't have to put a muzzle on him at all during the visit. Before we started the training, Roscoe's aggressive tendencies were beginning to interfere with our life. We were unable to have guests over because of his aggression. Trips to the vet were very difficult and even car rides were stressful because of his territorial behavior. I am so thankful that we found Bark Busters and were able to learn what it takes to establish ourselves as pack leaders. It is nice to see Roscoe just "being a dog" and not worrying so much about protecting us. Thank you so much for giving us the tools to help us with our sweet dog!
