Potty training is the process of teaching a dog to eliminate in an appropriate area, such as outside or in a designated potty area. It involves teaching the dog to recognize the signs that they need to go, and then providing them with a designated area to do so. Potty training is important for keeping the home clean and for teaching the dog not to eliminate in the house. Trainers typically use a combination of positive reinforcement and consistent routine to teach dogs to be potty trained. The process usually starts with crate training.
