Bought this dog crate to fit both our spaniels in the Defender but being spaniels they prefer to roam free in the back of the car rather than in a crate
The dog crate is also certified to take on airlines or ships if you are transporting your dog. This is a seriously large and robust dog crate which has been only used a handful of times.

Would suspect it would easily fit a medium sized dog i.e. lab or couple of smaller dogs. The crate if pretty big so probably better to take your car with you to check the crate can fit in it.
I think we bought it from Pets at Home for £160 (linked website has it at £268) but we are just looking for £75 for a S.Eliser.
