Awhile ago my husband and I were interested in getting a soft crate, and we were actually going to get this one but it was on back order and we needed a crate sooner than later. This soft crate would most likely work for you, I'm actually still interested in getting it out of convenience. Dimensions are 48"L x 32" W x 38.5" H and I'd recommend taking a look at the reviews, some people bought the crate for their great dane or irish wolfhound.

Also, just came across this one. It is slightly shorter and a lot more expensive, but better reviews on average.

Anyway, good luck finding the right soft crate!
