Mickey's water gets taken away by 9. We (well my parents) go to bed by midnight. If they see he needs some water (he'll walk over to the bowls or where they're supposed to be) and stay there. Then that means he wants water and then he'll get some. I know it might sound cruel but he adjusted to it well so it's all good. My mom told me about this lady she met the the vet who gave her dog one bowl of water a day. The dog "learned" how to have only a certain amount of water so that by the time its finished, he won't want anymore. Now that's just cruel.
