If your puppy (or dog) is in need of potty training, the best method would be to paper train him. Crate training can be used at the same time you're paper training him. While you're away, putting your puppy in the crate is a good way to keep him from wetting (or "going #2") on himself. Puppies don't like to wet themselves, and will try very hard not too. So it is important to get a crate small enough so that they don't have room to go in one corner of the crate and then be clean in another corner. You can find out more about paper and crate training in a Google search. You'll get tons of helpful websites. The website in related has information of both paper and crate training in it.
