Double trouble

Here is Rusty with Othello, another Airedale who sometimes walks with what Rusty considers his pack (a group taken out every day by our friendly neighborhood dog walker). Othello is quite handsome but “doesn’t listen,” so is never allowed off leash. I know I’m guilty of anthropomorphizing, but it always seems funny to me that purebred dogs don’t seem to recognize others of their breed. Rusty is no more interested in Othello than in any other dog, and Othello doesn’t seem to care much about other dogs at all. He’s in his own world.
