My 6 month old 25 pound Bi Blue Sheltie loves it. It's high, wide, and long. I keep it outside. My house is small for the large size, it takes up a lot of room if you have a small space. I'll throw balls or toys inside and she will play and fetch. She will sleep in it. It's more convenient than a metal crate, which I don't use, because I use a doggy door. It's less hassle with a bulky metal crate. It's her little getaway space from the other dog who's afraid of it and trys to steal her treats, so Presley conveniently takes her breaks and naps inside of it. It folds easily for travel to the outdoors or someone's home. It's definitely an amazing and versatile crate carrier.
