In some situations, even if you have an Ezydog harness, walking the dog outside to defecate is difficult. For example, some people work a lot, it is difficult to move, or the weather could be more favorable. In these situations, pee pads, mats, or diapers are ideal. These devices are helpful and almost indispensable for training the apartment-dwelling puppy to urinate in the predetermined place. The puppy pads should be placed near the cot where they sleep to familiarize themself with where they need to defecate.
