Love my expen. I have the 36 in so nothing jumps out. I have had it for about 8 yrs so they last a long time. I put 2 of them so they have 16 sq feet to roam. I use it camping and only when we are outside. Never alone. I hate seeing dogs tied out poor thing never stop barking. My brother uses his inside at night for them to sleep in. Hope this helps |
