Dog ramp (Sutton NR12)

Hi, I'm looking for a dog ramp to get my ageing greyhound in and out of the car. He's not as nimble as he was and at 36kilos he's a handful when it comes to trying to help him. We're not too sure how he'd get on with a ramp, hence why I'm asking if anyone has one going spare, just in case it doesn't solve the problem in which case I'll re-freegle it
