Thanks for the overall height - I'll consider that when buying another car next year, though would need a reasonable height and low back for the dog.
Just thinking - regarding getting it into the car. How about one of those fold up dog ramps you can get, then you could wheel it up the ramp into the car maybe? - push or drag it, probably more control if you push.
I'll need to get a ramp for my dog at some point so may consider a wheeled case now that has come to mind. At 4ft 11ins I need something to help me take it anywhere!
