My vet suggested not leaving any water for him as long as I am not gone longer than 3-4 hours. I stopped leaving water & it seemed at first to stop him from peeing but only for a short time.
I feed him early enough in the day that he is out of his crate for several hours after eating. He isn't even crated daily because my sister is home from college right now & thus home during the day a lot. It's only when she has to go out that we crate.
His crate being too big may be a possibility. It's a good size crate because I wanted him to have room since when I lived in FL he was crated for closer to 6 hours at any given time. Plus in FL he was still sleeping in his crate. I guess I could give a smaller one a try…
As far as leaving him uncrated, we are working towards that. We leave him out if it's only like 30 minutes or so to try to see what he'll do. My goal is to eventually always leave him uncrated but right now I just don't trust him enough. We left him uncrated in my room one day & he ripped a huge chunk of the carpet out [down to the concrete!] So…yea. Haha.
