Overall Gunner is an AWESOME dog. The only problem that I'm having is when I take him somewhere new. When I open up the back of my SUV and get him out, he immediately starts growling, barking, and his hackles go up. It's only in new places. Yesterday I parked somewhere different at the park, and this morning we went to my regular vets office for his last set of puppy shots. Both times, he came out of the car and went a little nuts. There were people around in both places. As soon as I walk him around a minute, he's completely fine. At the park, he ignores other people and dogs. At the vet clinic, once we got inside he was an angel. He was very friendly to all the staff and didn't even flinch for his vaccines. How should I handle this behavior? I really think it's insecurity that is causing it. I'm socializing the heck out of him, but when he's acting like that, what should I do? I tried to correct him yesterday but honestly I think it just made it worse. Today I completely ignored the behavior and stayed calm and confident and he got over it much faster. Anything else I should do or watch out for? Again, I really dont think it's aggression although i could see how a stranger might think differently. Gunner is not shy at all and typically seems pretty confident.
