We have a W+/- 60 pound dog and he destroy the fencing the very first day.  We even tried to use fencing wire/tie-down threading to secure the fencing along the bottom of the kennel but it didn't stop him from finding a way out under the fencing.  The door doesn't close all the way either. We had to buy an extra large carabiner to keep the door closed.  We finally gave up using the kennel and it's just been sitting unused. It's so destroyed from him escaping that we can't even resale it. (Not that we would sell it someone and risk them losing their dog.)  I wish I would have returned this as soon as we realized it would not hold our dog.
