House training your pet can be simple when utilizing the benefits of the Dog Potty Grass by Petmaker. This puppy potty training grass is equipped with a three-layer system designed with a plastic drainage insert that allows liquid to empty into the durable collection tray on the bottom and comes with 3 replacement artificial grass pads that can easily be swapped out while cleaning, so your cat or dog always has an acceptable place to relieve themselves, which ensures a cleaner house, apartment, or patio. Each dog grass pad is meant to be reused to save money and prevent the waste that disposable pee pads create. NOTE: The set of artificial grass for dogs and dog potty tray will ship separately and may not arrive together.
