Am..my husband thaught that it's not a solution if we change the wee pads- we have to find out why they do that..---he's reading a Cesar Milan book right now

So right now we're just trying to figure out whats wrong.
But we both found that the x-pen is really needed, as some of said that they have too big playground.
