Instructions
Determine if you're leaving your dog in the crate too long. The most common reason dogs pee in their crate is that they simple can't hold it any longer. Young puppies should never be left alone for more than three hours. When you first begin leaving your dog in the crate, you should start in small increments of time -- 30 minutes or so -- and gradually build up to longer time spent in the crate.
Walk your dog immediately before you put him in the crate and immediately after you take him out. This ensures he has an empty bladder in the crate and helps him to understand that the crate is not for peeing.
Make sure the crate is the right size. Dogs should have a crate that is large enough to lay down and turn around in, but if the crate is too large for your dog, she's likely to pee in it. If you have a very large crate, consider blocking off part of the crate until your dog gets bigger.
Remove absorbent material. Dogs are more likely to pee in their crates if there is absorbent material in the crate. Take out any absorbent material until your dog stops peeing.
Play with your dog before putting her in the crate. This helps to burn off energy and makes it more likely she'll spend her time in the crate sleeping.
Peeing in Crate While Crate Training
Crates can be an incredibly effective tool for housetraining a dog. When a dog begins to pee in her crate, however, it can prove to be a huge obstacle to training. It's important to intervene and figure out the problem as soon as possible when dogs begin peeing in their crates. Waiting too long can make it impossible to use a crate to train your dog in the future.
