Puppy pads are one of the most popular ways to potty train a dog and it's easy to see why. For pet parents who live in an apartment building and don't want to constantly trek up and down stairs to take their dog outside, they're incredibly convenient. They're also useful for pups who must remain inside while their parents are out during the day for work. And, despite the name, puppy pads don't have to be used with only puppies, as they can also be beneficial for senior dogs who are incontinent.
