This worked out great for us, we are using it to put a cat in while we have to move out of the house for a repair for a few days.  Planning on moving into our travel trailer with out cats and dogs for 3 days. Using this to keep a cat in at night along with a small potty box. Purchased 3 and they fold up nice for storage.  It definitely would not hold our Shepard and he is only 55 lbs. 

Pros: Folds up nice for storage
Cons: Not large enough for a Large dog.  Maybe 30 - 40 lbs comfortably
