I'm one of the detractors of the Wizdog. I wasn't impressed with it at all. It really just didn't do the job I was hoping it would. It also seemed really flimsy and cheap. One of the big things I didn't like about it was that it's too big for a standard size wee wee pad and is better suited for newspaper. I ended up just buying some chicken wire w/ smaller holes and attaching it to my pee pad frame and that's worked great and only cost a few bucks. I've also still be considering getting this
one from Puppy In Style. It's cheaper than the Wizdog and looks a little higher in quality.
