Dog ramp or dog stairs?
Measure the height first
Tape from the ground to the spot where your dog steps in: the cargo floor or the bumper of the SUV, the sofa seat, the top of the mattress. That one number decides the length you need. The slope of a ramp is set by height and length:
| Height to climb | 65 in ramp | 71 in ramp |
|---|---|---|
| 20 in | about 18 degrees | about 16 degrees |
| 24 in | about 22 degrees | about 20 degrees |
| 28 in | about 25.5 degrees | about 23 degrees |
| 30 in | about 27.5 degrees | about 25 degrees |
| 32 in | about 29.5 degrees | about 27 degrees |
| 36 in | about 33.5 degrees | about 30.5 degrees |
Many ramp makers and trainers aim for a slope of about 25 degrees or less, and lower is better for small, older or nervous dogs. If your cargo floor is above 30 in, a 71 in ramp is the one to get.
Ramp or stairs: how they compare
| Folding ramp | Folding stairs | |
|---|---|---|
| How the dog climbs | Walks up a slope | Steps up 5 times |
| Best for | Seniors, big dogs, long backs, stiff joints | Agile dogs, tight parking spots |
| Length on the ground | 65-71 in | about 40 in |
| Weight to carry | 16-20 lb | about 10 lb |
| Folded size | from 18.3 x 17.2 x 5.1 in | 18.7 x 15.7 x 5.1 in |
| Rated load | 250 lb | 250 lb |
Stairs need less room behind the car, which matters in a garage or a tight parking space. A ramp needs 5-6 ft of clear ground, but every step is the same easy walk. Dogs with long backs, such as dachshunds, corgis and basset hounds, and dogs with sore hips or elbows usually find the ramp easier. If your dog has a diagnosed back or joint problem, ask your vet which they prefer.
Width and grip
A big dog walks straighter on a wider ramp. The two ramps below are 17.2 and 19.3 in wide; the wider one leaves a large dog room to walk without hugging the edge. Look for a carpet or rubber-textured tread and a strap or hook that holds the top to the car, so the ramp cannot slide while the dog is on it.
Couch and bed
Indoors, the heights are lower and a short ramp is enough. The Ottoman Ramp opens into a 31.5 x 15.75 in ramp at a 23-degree slope, about 13.6 in high at the top, which suits a sofa or a low bed, and folds back into a 15.75 in ottoman. For a tall bed, a folding car ramp also works indoors; the 71 in aluminum ramp below is sold for cars, sofas and beds.
Teach it before the trip
Lay the ramp flat on the floor and reward your dog for walking along it. Then raise one end a few inches, then a step or the sofa, and only then the car. Short sessions with treats work better than pulling the leash, and the first time at the car, hold the ramp steady with one hand.
