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 grass pee pad is meant to be reused to save money and prevent the waste that disposable pads create. NOTE: The set of artificial grass for dogs and dog potty tray will ship separately and may not arrive together. Petmaker Size: Small (20" W x 16" D x 1.25" H)
