Bests & Worsts Reviews from Amazon

I've been generally happy with this product until a few days ago. Like usual, I put my puppy in the pen and went to bed. When I woke up I found him running around in the house, chewing on the electrical wires. I yelled at my poor boyfriend for letting him out without supervision. It turned out my puppy's legs grew just long enough for the vertical spacing, and he climbs out of the pen like it's a ladder. I just ordered 24" x 42". I am hoping he won't be able to climb out of this one. If he does, I'm officially registering him as a circus dog.
