Can anyone tell me what is an x-pen? I get that it is some type of pen, but exactly what is it & where do you purchase one? My house is impossible to gate off, so I'm very interested in finding the best way to confine Mojo to a smaller area. We are crate training & he's doing so-so. I have been reading all the great advice on this web site & it's really helped alot. Thanks to all who contribute.
