Fresh water is available at all times here.......

Even in the middle of the night. I guess that's not a good idea, but I've never had a problem. Nebo sleeps in a kennel in my room at night. I noticed in the mornings when I'd let him out the first thing he'd do is go to the water and drink like crazy. So I attached a water bottle to his crate. It gets pretty hot in my room sometimes, and he seems much happier with the water. He always goes potty first thing in the morning, and never goes in his crate.
