If that one doesnt work out for you Ive got a 10 x 10 x 6 that Ill take $75 for.
Thats what I paid for it a few weeks ago. Its got some minor damage (wire needs to be tightened in a couple of places/bottom rail is bent a little bit but could probably be straightened).
Itll hold a dog fine but Im going to pour a concrete pad someday and I want to use some panels that are in a little better shape.
