I've read that dogs should have their water taken away at a certain time. I think that's a horrible thing to do. Kai doesn't have food sitting all day so he may go a bit hungry but the water is left so he can satisfy himself. Also, Kai is potty trained and gets taken out right before bed so too much water before bed isn't an issue. Also, dogs can last a while without food but water is essential. Lastly, Kai has ALOT of fur and especially since it's summer time now, he may feel the need for a drink during the night to keep him cool. All in all...i think it's a bad idea to take water away at any time.
