"Not housebroken" refers to pets, particularly dogs, that have not been trained to defecate and urinate only in designated areas, such as outside or on a puppy pad. Some synonyms for "not housebroken" include "untrained," "unaccustomed to indoors," or "not potty-trained." A pet that is not housebroken can cause inconvenience and mess inside a home, particularly if it is left alone for long periods of time. It is important to train pets to be housebroken in order to maintain a healthy and hygienic living environment. Consistent training, positive reinforcement, and patience are key in successfully housebreaking a pet.
