I have strangers stopping and saying hi to my dog--they know her name, because they met her weeks ago in the pet store, at the auto mechanics, out side the grocery store. She is a total social diva.
My boy is just excited to see everyone. Friends/foes/intruders, everyone.
Haha, Betty is like this as well, if someone pets her at the dog park, I swear she would just go home with them. Loves any attention!
