We have a 5 1/2 mos old male boxer that I keep in the crate while we are at work. We started coming home at lunch each day to let him out but found that he was peeing in his crate each day. After a while we wondered why we were coming home at lunch if he was going to pee in his crate no matter what. He has to be in there 8-9 hours per day. He is able to hold his bladder at night from about 9 at night to about 7 in morning - and he doesn't sleep in his kennel at night, he sleeps on our bed. My breeder says he needs to learn the discipline of holding his bladder during the day like he does at night. I put a fleece in his crate that seems to absorb the pee and have found a few times where he didn't pee on the fleece and just stayed away from the pee as best he could, so it seemed like it didn't matter whether or not there was something in the crate with him to absorb the pee. This is my first boxer. My last dog was a Lab and he seemed to get the crate thing pretty early on and was able to hold his bladder all day by this age. I hoping to get some advice or hear from people who have had similiar experiences. One more thing, he is doing great as far as the not peeing/pooping in the house. This only happens sometimes when we don't see him go to the door or hear him cry out, so it is usually our fault.:confused:
