I suppose it really all depends on a few factors how large your dog is, how long he/she will be in there, what purpose are you using it for i.e. transport, crating while you are at work or what have you. Placement is also important as MM pointed out (good thinking MM). I say the bigger the better if its for crating the dog while you are at work. I know i wouldnt want to be all cramped up for long periods of time. They need room to move and stretch. Hope this helps in your search.
