After losing Maggie last spring, I'm finally getting a new puppy this month. She will be living in the house and housed in a 42" crate. I'll need a travel crate for my Ford Explorer, and am thinking of a 36" x 22" wire crate, as it is lighter and less expensive than a plastic one. Will this be an adequate size? She will prob. be small, as both the sire and dam are 50-55 lbs. She won't be living in it, just when we're traveling on the road (trips less than 2 hrs).
