If your dog has an incontinence problem the best way to go is to get bed pads, which are basically a diaper that you can lay flat on the ground. You can train your dog to use the bathroom on these sheets. They were great, every time my dog had to go he just went on the bed pads and I just roll the sheets up and threw them away.
