Chihuahua puppies can be trained to potty outside, on paper or in a litter box depending on the owner's preferences. Constant supervision of any puppy is key to successful housebreaking. Puppies may need to eliminate as often as every 15 minutes. After every nap, meal and play period, the puppy should be taken to the correct spot and praised for its successful elimination.
In addition to taking the puppy out at scheduled times, owners must watch the puppy constantly for signs of an impending bowel movement. Circling, sniffing and starting to squat are signs the puppy needs to go. Even if the puppy has an accident, punishment should be avoided. The puppy may not understand the reason behind the punishment, and it is always the owner's fault for not supervising the puppy better.
When the puppy cannot be supervised closely, it can be kept in an exercise pen with a litter box or potty pad at one end and a bed and food at the other end. Puppies do not like to eliminate where they sleep and eat, so they naturally seek out the pads or litter box at the other end of the pen. Puppies should not be allowed to roam free in the home unsupervised.
