What's the ideal size water bowl for a dog?

You really ought to clean it often so any size works? It’s not like you can get a huge one just so that you don’t have to refill it often

Something bigger and less attractive than the toilet?

one that don't need refilling often!

In my 'humble' opinion, that would depend on many factors.
