I think its best if you leave it open for your dog. just because their is a door it dosn't mean you have to use it!
my first bitch who died about a year ago was a cow when it came to her cage. sometimes we would take it from under the stairs and want to put it in the car so we coudl take it to a show, it was collapsed in the hall and we had to literly drag her out and put her in the kitchin so we could collapse the cage without her stopping us!
a cage is a place of security for a dog because it protects them from all directions. i wuold say leave the cage unless its to small for your dog now and then i would recormend gettinga biger one!
