To stop a puppy from peeing inside, it's crucial to establish a consistent routine for potty training and reinforce good potty habits. One effective method is crate training, where the puppy is confined to a crate when unsupervised and taken outside immediately after being let out. Puppies should also be taken outside to pee after eating, drinking, playing, and waking up from naps. Consistent praise and rewards for successful potty trips can help reinforce good behavior and speed up learning. It's also important to supervise the puppy closely and prevent them from having access to areas where they are likely to pee inside. This may involve using baby gates or closing doors to prevent access to certain rooms. Suppose the puppy does have an accident inside. In that case, cleaning it up thoroughly with an enzymatic cleaner is essential to eliminate any lingering odor that may encourage the puppy to pee in the same spot again. With patience, consistency, and dedication to potty training, a puppy can be successfully trained to pee outside and establish good potty habits.
