Jax does it
All the boys in his litter at the breeder did it too!
In the summer months I keep the water bowl out on the deck off the kitchen and they ask to go out to drink/swim in the bowl. I even tried allowing them to drink out of one of the toilets we don't use but they started drinking out of the others so we stopped that.
Then I tried placing the water bowl in the garage but the door is out of the way and I couldn't tell when they wanted water so it's in the kitchen again... sigh.
I've heard of people installing bedays in their house as dog bowls which is really cool because you can just change the water by flushing
I'd love to put one in the basement for that.
When we were looking at houses, we saw a house that just hooked up a toilet in the middle of the basement to the rough-in that houses usually have (with no walls around it) and everyone made fun of it except me... It was clearly a dog bowl lol.
