I have a chihuahua, and for the price, you can't beat this little puppy retreat.  He has enough space during the day while I'm at work, and it keeps him safe and out of trouble.  The portability of this thing is key as I often have to bring him to his Nana's while I'm traveling for work.  Easy to clean up messes inside, and the velcro on the bottom is okay, but he figured out how to flip up the edges.  I would recommend putting it on top of a rug or something so if they do get the bottom up, they won't make a mess on carpet or wood floors.  It fits a potty pad, food water and TWO beds in it; great value.  Also, he hasn't torn at the screen (or I haven't seen any damage of the screen), so it's probably pretty sturdy too.  In my opinion, can't beat the price and value. Great puppy retreat!
