Many people are leery of leaving their dogs out overnight at home, or travel often and want their dogs to be comfortable in a crate while doing so. If you want your dog to sleep in a crate, potty in a crate or just be comfortable while traveling, crate training is the first step.
If you are training your dog to potty in the crates, there are special wire crates made with a pan that will sit beneath the floor of the crate for paper. Place the paper in the pan, spray with the potty training spray aid you use to potty train the dog, and slide the pan back underneath the floor of the crate. If your dog is already paper trained, he or she will start to look for the paper. Make sure you place the crate near the same spot you have been putting paper down, or your training will not work. Slowly, start moving the paper he or she uses towards the crate day by day, so that the dog understands that the paper will be in the crate. The last day of training, do not place paper outside of the crate, but only in the crate. Once the dog enters the crate, allow him or her to eliminate, and then remove the paper from the pan and replace with a new paper.
If you have not noticed in the past, many dogs will not go to eliminate in areas where there is already waste materials. So, if you leave dirty paper in the crate, they may not go into the crate to potty. Every time the dog goes into the crate to eliminate, give him or her a treat so they understand this was a good behavior. Tell the dog they did a good job, and allow him or her to gloat. Do this for a week, and then no longer put the paper out on the floor. The dog will seek out the next place with paper, which will be in the crate. You should be proud of your dog, he or she not only uses the paper, but is learning to do it in private in an area that is easier to clean up and cannot be walked on.
