I wish I had purchased two of these. This is the best Double Door Pet Crate I have. I have enjoyed the double entry and the ability it affords my tall Golden Retriever to stand up and move around with ease. It can be used by two dogs if
they are friendly.  Our area is inside the house and at times I see the most use of it. I would recommend this to anyone that want to give their pet more room for exercising.  What a great buy.
