easy to assemble

This is everything as advertised with one flaw I've noticed. The zipper is too hard to close. It is light weight, easy to assemble, but once assembled, the canvas cover is so tight that the zipper is difficult to close. I feel that I am nearly breaking it just to get it closed. The top zipper is easier than the front opening. Hopefully I will be able to find a solution to this. Everything else is good except for the most important part... closing your dog in!
