totally! it's a learned, and unlearnable, thing. What do I mean? When I got Buddy at 6 months old, he didn't know how to lift his leg. He learned it from watching other dogs at the dog park!! Well, a few years ago, when he was 6 years old, I took in a stray girl dog for only a few days. She was pretty dominant, too. Well, guess what happened??? He started watching her, and he stopped lifting his leg!! I couldn't believe it. As soon as she was gone, he started lifting it again.

Talk about impressionable, and subject to peer pressure!!
