I'm absolutely in shock right now. I took Oscar for a walk to a small park in our neighborhood. I tied him up to a long lead so he could run around a bit and we could work on the "come" command. Since it's early afternoon on a weekday, I figured we'd have the place to ourselves while we were there. Boy, was I wrong. Within about 15 minutes, there were three labs and a retriever all running around off leash. I thought poor little Oscar was going to lose his mind. I kept him on his rope so he could run around if he wanted, but not get too far away from me. I was anticipating some fear based aggression, but, miraculously, there was none! He greeted the other dogs with his tail up, let them sniff him and even ran around with them a bit. When they got a little too forceful with their sniffing (one of them practically picked Oscar up with his nose), I stepped in to protect him and show him I had his back, which is what the behaviorist said to do. He would venture out to play a bit, then always came right back to me so it's definitely working. And he only barked one time out of excitement when the other dogs all ran right past him at full speed chasing a tennis ball. The whole thing was absolutely amazing to watch and a total breakthrough for Oscar. YAY! The only bad thing that happened was when he lifted his leg and marked the back of the pant leg of one of the men. OMG, I was so embarrassed. I don't think I've ever apologized to anyone as much as I did then. Fortunately, he was a good sport about it and didn't seem pissed off. I'm definitely going to have to keep a closer eye on the muttley when we're meeting new people. Yikes.
