Our Four Paws Wee-Wee Dog Grass Patch is a great indoor or outdoor potty-training solution. This small dog grass pad has built-in attractant that helps draw your dog to the pad and lets him know where to "go." The realistic dual-length dog training grass gives the patch a more natural feel under your pup's paws. The durable tray has an easy-drain pour spout to make cleanup quick and easy. Dog potty training grass available in small (20 x 20in.) and medium (20 x 30in.).
