Teaches himself trick

The small mountain of fur shook itself, and something thudded against the wall beside it as it rose up into the shape of a large, stocky dog covered in a thick shag of grey fur, complete with an almost leonine mane of darker fur around his neck, throat, chest, and upper shoulders. He went to Murphy straightaway, sitting and offering up his right front paw.
Murphy laughed, and grabbed his paw briefly-her fingers couldn't have stretched around the offered limb. "Hiya, Mouse." She scratched him behind the ears. "When did you teach him that, Harry?"
"I didn't," I said, stooping to ruffle Mouse's ears as I went past him to the fridge. "Where's Thomas?" I asked the dog.
Mouse made a chuffing sound and looked at the closed door to my bedroom. I stopped to listen for a moment, and heard the faint gurgle of water in the pipes. Thomas was in the shower. I got a Coke out of the fridge and glanced at Murphy. She nodded. I got her one too, and doddered over to the couch to sit down slowly and carefully, my aches and pains complaining at me the whole while. I opened the Coke, drank, and settled back with my eyes closed. Mouse lumbered over to sit down by the couch and lay his massive head on one knee. He pawed at my leg.
