I am a horse trainer and take my dogs to the barn with me every day. I use the pen when I am riding and can't keep an eye on the dogs. They love it because they can still see all the goings on. I have gotten so many compliments on how attractive it is, everyone wants to know "where did you get that, so cute". It was easy to assemble and is very sturdy. I may get the new smaller size to take to horse shows. Love it!
