I have this one in blue. My more ladylike Yorkie uses it fine cause she was used to it when I got her.(at 6 months) On the other hand, my monster, tomboy pup can get out of it. Somehow she finds a way to jump or climb out. I probably would not leave any of mine in it when I'm not around to check on them. I have two other ex pens for that. It is good for taking to other peoples houses and stuff if you don't want to use a small kennel or tote. My relatives think I'm nuts when I set up a playpen for my dogs!!
