I'm going to agree with JohnQ on this. It's more attractive, but most importantly the Ugodog is better than the Wizdog because it has two separate grid panels (vs. the one panel on the Wizdog) so that you can remove and tilt them in so that solid waste can just be rolled onto your paper or pee pad lining. I researched both before getting my puppy and the Ugodog won me over. Very happy with the purchase and it's working well for training.
