How often do you change your dog's water?

[slleipnir]

I change it whenever needed. Sometimes the cats play in it, and it gets a little dirty...I clean it then, or whenever they are low (atleast once a day)

Gonzo has a huge stainless steel bowl outside, 1 big ceramic bowl downstairs and one upstairs in my room, and all are re-filled every morning. I guess he has too much water to go through.
