Dog crate is nice but I had two problems.  1. I haven't been able to put the side pieces on because it requires at least two people to do this. One to hold the sides straight while the other puts the top on.  I tried for 30 minutes by myself & gave up.  2.  The door way into the crate was about 4 or more from the bottom.  We had to cut the metal away so that my elderly dog could go into the crate.  She could not jump over the 4, especially with the height of the door way itself.  The design is meant for someone to place an animal into the crate instead of the animal walking into the crate.  I now have cut metal & a gap under the door if it is closed.  OK for her as we duct taped the sharp cut edges and she loves to be in a crate especially with the door open, but a small puppy could escape.
