He is absolutely smitten with my Shelley, though. When she was a tiny puppy (10 weeks) on her first walks through the neighborhood, we passed Sidney's house. Of course he came boiling up to the fence barking his head off - I expected Shelley to roll over - instead she went straight out to the end of the leash at him and barked at him right back. It was love at first sight. She is now almost 4, and whenever we pass his house Sidney trots up to the fence with his tail wagging and puts his nose through to greet Shelley. They have met outside on the sidewalk, and Sidney's owners were a little apprehensive at Shelley's boisterous bouncing on the end of her leash until Sidney puppy-bowed to her and kissed her!
She is the queen of all clowns, so I guess opposites attract.
A lot of the males aren't good players with other dogs just because they are so Alpha. But his dogs I've seen playing with others. ~His~ sport dogs aren't aggressive. The bite work is a game. In those videos you'll see them working bite work ON Wayne. It's just a game with a guy in a bite suit. They'll play with the teasers after the game is over.
It's funny because when they've done well, the dog 'wins' the bite arm. I (joking) asked him if the police dogs he's sold ever are disappointed when the arm of the bad guy doesn't just come off. He said with a straight face "sometimes it does" ;~D
