I'm really disappointed to say that I think I have to return the large pen I got. I do love it, but it's just not enough to contain Max. He and Cooper have been playing in it to get used to it. Max does like it but he also likes to eat parts of it. While the entrance was rolled up, he ate part of the bottom of the zipper. I was able to seal the door shut, but I'm not sure this will work. He likes to dig and scratch at the floor and windows.
I may have to get something else
