Boxer Classes

Oscar is getting bigger, he now goes to Boxer classes. He has many friends he is so friendly and sociable. I think he needs a playmate though but "Computer says No".
For some reason he likes to greet other boxers with his bottom? Maybe he is Gay? Ho do you know if a dog is Gay? Anyway, his training has been very succesful and he has completed his Kennel Club Bronze Citezens Certificate, he is proud and so am i, my baby. He gets a professional photo done but insists on showing his teeth...again.
