Like with regular potty training, you'll need to teach your pup to use the puppy pad. It won't realize right away that you intend for it to go potty there. Start by keeping track of your puppy's potty schedule. For instance, it'll likely need to potty in the morning. When you first start using a puppy pad, take your dog to the puppy pad at its normal bathroom time and encourage it to go. Then, praise your dog when it uses the puppy pad to reinforce the behavior. Additionally, monitor your dog throughout the day so it doesn't have an accident. If an accident happens, just clean it up with an enzymatic cleaner. Soon, your puppy will learn that the puppy pad is where they should go potty.
