Wo0t! Way to go HBH! LMAO.
Oz would do that too Angel Chicken. He will sniff their face, and front legs and shoulders, dance out of the way if they try to sniff his butt, and then procede to flip his butt around while placing a paw on the other dogs back.
I've had to interrupt this, and find a different way to teach him to greet other dogs after we got attacked. He was worse meeting dogs after that, so, teaching him to NOT put his paws on their back was the name of the game. Because after that, if he got to the part where he put his paws on their backs, if they made eye contact, he would grab their face in his front teeth and try to pin them or shake them. I'm not sure if he was really trying to pin them, or just have a "I'm badder, bigger, and meaner than you too" scuffle.
Whatever he was doing, he's stopped, and gone back to greeting like he owns the world, but not trying to eat them if they look at him. Lots and LOTS of PR did that.
