Potty training a puppy is a little trickier when you have an apartment, since you can’t install a doggie door or easily let your furry companion outside. The key is to start early and be consistent. Place your dog on a regular feeding schedule so you can predict when she’ll need to go outside, and reward her every time she demonstrates good behavior. Before you know it, your puppy will run to the door and wag her tail instead of having indoor accidents. Read on to learn more about how to potty train a puppy in an apartment.
