Should I change my approach when introducing myself to people?

Yesterday I was talking to the new neighbors. I only met the husband once and hadn’t met the wife yet, so I was basically introducing myself when I said hi to them.

I thought I did pretty well. We were making jokes and whatnot and it was fun. But then something happened that made me question my approach. My dog managed to get plenty of attention by walking up and humping the guy’s leg. Should I do that from now on? Maybe people will think it’s cute. :)
