Oh yes. When he was a tiny puppy, I thought, “a few messes here and there on my plywood floor aren’t that big a deal…” Then he grew and so did the puddles. I trained him to use the cat box to pee in if he was inside, like in the middle of the night, and he does everything else outside. He scratches at the door when he needs to go out.

When we are at houses that actually have indoor plumbing, I show Charlie the shower or bathtub upon arrival and when he needs to go, he saunters into the bathroom, hops in the tub, and pees down the drain. Then I turn on the water to flush it. It’s a handy trick.
