Wizdog is a new revolutionary house training system for dogs. Consisting of a durable plastic pan and fitted grate, liquid waste dispenses through the grate onto newspaper or a pee pad, separated from your dog's paws - No more wet paw tracks throughout your house! Solid waste stays on top of the grate, so you never have to touch it. Just flip the grate, and it's gone. That's it! The simpple, quick and easy way to take care of pet waste disposal.
