we got our new puppy on Friday, apparently he thinks he is spider dog and is climbing the sides of the xpen to escape. he also climbed over a baby gate, so the boy got through two layers of protection to get out.

Honestly I don't know how he is doing it without hurting himself. he is landing on tile.
I really like the xpen for day purposes because it gives him room to play, have a bed, toys, food, water, even his crate is in there so he has access to his "den". what can I put over the top, the pen is pretty big so I am not sure what to use.
