I have a Great Dane puppy who at 9 months old is 35 inches at front shoulder and 133 pounds. He has been crate trained since 8 weeks so he is used to being crated. This has been an excellent purchase. It arrived quickly, was in good condition on arrival. A minor bend in the metal tray was easily bent back with little efford, it was easy to set up and he loves it. He can lay down comfortably and has room to grow. The metal is not as heavy duty as other crates I have bought so if you are just beginning crate training or if you expect your dog to try to escape, I may recommend going with a heavier duty crate (ie more expensive) but if you have a crate trained dog that needs the room, this is a great find. It is an extra large crate so as expected, it is quite heavy, I do not tear it down and set back up unless absolutely necessary because it is something like 70lb which is too much for me to lift myself. However, it is easy to disassemble and reassemble so if you have a large enough car and muscles you could use this as a travel crate for a giant breed dog. Cheers! Sara and Angus
