Many of you know Ozzy. Some of you know that he was/is on leash dog reactive. I think, well, I'm pretty sure, that he has crossed the line into full blown dog aggression. Long story short, we got attacked on a walk. Twice. Once, the other dog and Ozzy came into physical contact with each others teeth, and the other a Chihuahua charged us and I dragged Ozzy out of there. I had never heard him make a noise like the one he made towards that dog, and I know, almost without a shadow of a doubt, if that other dog had made it to us, Ozzy would have seriously injured or killed it. We had made a TON of progress in pet stores, mostly PetSmart, and it hadn't been a problem outside as much as it was inside. Now, I'm not so sure. And I'm not sure what to do. I can get his focus indoors, and I had him outside, but now, I pretty much cease to exist for Ozzy when we are outside and there is another dog outside. We just started working with a clicker, what kind of games can I play to teach him to focus on me? I do NOT care if he can't be every other dogs buddy. In fact, I really don't plan on letting him greet other dogs unless they are friends dogs, and that will be done offleash. He does fine off leash. I just want him to ignore the other dogs. Pretend they don't exist or just, whatever. How do I accomplish this?
