I got a Ugodog about 2 months ago for my Yorkie. He has been trained on puppy pads so what I do is put a puppy pad on top of the Ugodog. He doesn't really notice that it is anything different.
What i do like is that now his urine doesn't soak through to the floor. This was a big problem for me and eventually your floor will smell bad and you won't be able to get it out. (I just replaced my floor!)
He took to it pretty well so I am happy with the purchase.
