Length is the spec that decides everything
A ramp’s job is to reduce the angle. The steeper the ramp, the less it helps, and past a certain point a dog will simply refuse to walk up it. Length is what controls that angle, and it has to be matched to the height of the surface you are loading onto.
| Vehicle | Rough load height | Ramp length to look for |
|---|
| Hatchback / estate boot | Low | Around 60 in is comfortable |
| Mid-size SUV | Medium | 60–70 in |
| Full-size SUV / van | High | 70 in and up, or telescoping |
| Pickup tailgate / lifted truck | Highest | Telescoping, 80 in or more |
The honest way to check before you buy: measure from the ground to the lip of your boot. As a rule of thumb, a ramp roughly three times that height gives an angle most dogs will walk without hesitating. That is why the telescoping ramp exists — being able to set the length to the vehicle is the only real fix for a tall tailgate.
Grip matters more than the brochure suggests
The AKC makes the point that non-slip surfaces are what build a dog’s confidence on a ramp. This is not a comfort feature. A dog that slips once on a ramp will remember it, and you will spend the next month coaxing.
- Molded treads or a carpeted surface beat a smooth ribbed plastic panel. PawStep is explicit on its own listing that traction on the bare ribbed version varies with the angle and conditions — which is why the carpeted option exists.
- Side rails stop a nervous dog stepping off the edge, and they matter most on narrow ramps.
- Rubber feet stop the bottom end sliding on tarmac, which is the failure that frightens dogs most.
- Width. Sixteen inches is fine for a medium dog; a big dog on a narrow ramp is walking a plank. The telescoping pick here is 20 in.
Ramp or steps?
The AKC frames this as a genuine choice rather than a ramp-always answer, and the distinction is useful:
- A ramp is better for dogs with arthritis, hip or spinal problems, or anything post-surgery. Walking a slope asks less of the joints than lifting each leg onto a step.
- Steps suit dogs that are simply short rather than sore, and dogs that have had a bad experience on a ramp and now refuse them. Steps also fold much smaller — the Veehoo folds to about 17 x 13 x 6 inches, which no ramp does.
Introducing a ramp so the dog will use it
The AKC’s advice here is worth following exactly, because a rushed introduction produces a dog that will not go near the thing again:
- Set the ramp up flat on the ground first, at no angle at all, and let the dog walk across it for food.
- Raise it a few inches. Walk alongside, food in hand, and let the dog do a couple of steps rather than the whole length.
- Build up over days, not minutes. Never push, pull or carry the dog up it.
- Once it is in service, keep it consistent — same ramp, same side of the car, same routine. Dogs with sore joints do best with a predictable procedure.
And once the dog is in the car, the ramp is only half the job. The AVMA is clear that a dog in a moving vehicle should be restrained — in a crate, a carrier or a crash-tested harness — so a ramp gets your dog in safely and a restraint keeps it that way.
