On average, it takes about two months to potty train a puppy. Most puppies lack the muscle control needed to begin potty training until they are at least eight weeks old, and many are not ready until 12 weeks old.
Potty training for a puppy is based on two of his natural instincts: his urge to please his human pack leader and his desire to keep his den clean. He should be taken outside to a designated bathroom area after every full meal. If he successfully eliminates outside, he should be praised. A regular schedule and consistent reinforcement help him get the idea.
