How to housebreak a dog using a crate
Pick a crate that is the right size.
A crate should be just big enough for your dog. If it's too small, your dog will be uncomfortable.
If it's too big, your dog will have space to use the bathroom in the crate and still have a clean area. It should be big enough for your dog to sit up, stand up, lay down, and turn around, but no bigger.
