HOUSESOILING
Housesoiling is a spatial problem. Your puppydog has been allowed to eliminate in the wrong place. Housesoiling quickly becomes a bad habit because dogs develop strong location, substrate, and olfactory preferences for their improvised indoor toilet areas. To housetrain your puppydog: first, prevent any more mistakes; and second, teach your puppydog where you would like him to eliminate.
