My 2 year old lab has been house/crate trained for 1 1/2 years. He was able to hold his bladder from 7:30 am to 6pm while we were at work with no issues for over a year. Suddenly in December he began having accidents in his crate and it has continued since then. We took him to the vet several times to rule out any medical issues and he was given a clean bill of health (almost $500 later). We even went ahead and had him neutered over a month ago hoping it would help (even though he isn't "marking" the house, just peeing in his crate when left alone). One change that we wondered affected him is that I found out I was pregnant in December but this did not change his daily schedule he's been on since day 1. Our vet and his trainers do not believe my pregnancy has anything to do with his behavior. We began taking him out even more frequently as soon as this problem occurred and it does not solve the issue at all. We even resorted to gating our kitchen in hopes that if he wasn't confined in his crate he would be happier (he never had an issue with his crate prior to this, lays in there to rest even when having full access to the house). But instead managed to just pee all over the kitchen and go lay in the biggest puddle instead. I am at a loss and ready to re-home him as I cannot deal with the constant peeing and him smelling like pee because when he does it twice a day we can't keep him clean. HELP!!!!!
