Your Chihuahua puppy might be strong-willed, but before he leaves his litter he has already begun to separate his potty areas from his sleeping and playing areas. Your Chihuahua is small enough that he can be potty trained to go inside your house in the same place on puppy pee pads if you would like.
Training your Chihuahua to go on pee pads in your house makes for easy cleanup and is helpful for Chihuahua owners who don't want to go for walks outdoors or require their tiny little Chihuahua to walk in the snow and cold. This puppy pee pad potty training is also great for Chihuahuas who live in high rise apartment buildings or in the middle of concrete jungles. If you plan to have your Chihuahua in places other than inside your home, you may want to consider training your Chihuahua for outdoor potty as well as pee pads so he knows he can go elsewhere should that need arise.
Training your Chihuahua puppy to use pee pads when he goes potty will require dedication and understanding from you. You will need to be around often to pay attention to the signs that your little buddy needs to go potty and be committed enough to help him succeed. To do this you will need to understand when your dog typically needs to go. Once you have that understanding of his potty patterns down, taking him to his puppy pee pads, waiting for him to go, and rewarding him for good behavior is basically condition training. This will be repetitive training and will require having someone home during the common times your Chihuahua may need to go potty. Rewards based potty training tends to work better than punishment for poor behavior. To reward your Chihuahua, you will need to catch him doing a good job recognizing appropriate places to go potty.
Before you get started potty training your Chihuahua to use puppy pads, pick out an area in your home where you plan to keep the pee pads. This area shouldn't change and should be easy for your pup to get to. This might be a bedroom you don't use often, a bathroom, or even a utility room. You will need to have plenty of pee pads to lie down on the floor for training and enough for replacing dirty pads over the course of your training as well. Your Chihuahua will require rewards for good behavior and you may decide you would like to have your dog on a leash when you begin to take him to his pee pee pads to go potty. Avoid carrying your Chihuahua to his potty area or he will expect this all the time.
