My dog doesn't do that. Might be because I keep the toilet cover down, though.
My dog is not particularly smart, either. I leave him on the screen porch while I drive to the boat (an hour away) and do maintenance. I faithfully put his water dish out on the porch before I leave. When I get home, the water dish is still full. So I take it off the porch and put back at its regular place in the kitchen, whereupon he runs over there and slurps it all up as if he had not had any water for a week!
