This sounds like an unfortunate, but likely and kinda funny, outcome.
That said, my dog is a Boston terrier, and they mind the heat very much. It helps her tolerate the summer by letting her play in water occasionally. After all, she's watched me fuck, wank, lie around the house naked, and she lays down on the floor next to the shower when I get in. Why not let her get in under the tap and cool off?
I had a Boston Terrier as well, and I always brought him in the shower. I always wore my swimsuit or at least a top and some shorts. Oh, and whoever said Drano was spot on. Always good to clear the pipes afterwards. He would shed like crazy. I gave him a bath twice before deciding the shower route. There was so much hair in the tub it was grossing me out.
The reason I didn't shower him in the nude? One, I wasn't bathing myself, and two, when he leaves the shower he leaves the shower, and the thought of chasing him all over the house with a towel and nothing else would not be pretty.
