I've got a lovely dog called Mutt. He is looking sweet but when a stranger comes to the door, he often barks and is sounding really unfriendly! After a long walk in the rain, he doesn't smell very nice! His long ears feel soft and his nose is usually wet. When he is hearing his parents' car, he runs to the window. He's always seeming to know when they are coming.
