Shoulder height
Measure from the floor to the top of the shoulder while your dog is standing naturally.
Northbay sizing guide
Start with the numbers that decide whether a ramp, step, or stroller will actually fit your dog and your routine.
01 · The three numbers
Your dog’s weight matters, but dimensions and reach often tell you more about real-world fit. Take these measurements before comparing products.
Measure from the floor to the top of the shoulder while your dog is standing naturally.
Measure the space your dog takes up lying down, from nose to the base of the tail.
Measure from the ground to the lip, seat, mattress, or surface your dog needs to reach.
02 · Choose by movement
The right format depends on the movement your dog is comfortable making now—not what worked a year ago.

Start with cargo or seat height and the room available for a ramp approach.

Watch what your dog already chooses: stepping, walking an incline, or avoiding both.

Cabin dimensions and entry style matter more than a headline capacity number.

The same destination height creates a different incline depending on ramp length. Compare the geometry before comparing traction, folding style, or color.
The bands are a practical visual guide, not a guarantee of how an individual dog will respond.


04 · Stroller fit
A frame can support a certain load while the cabin is still too short, narrow, or difficult for your dog to enter. Compare the interior dimensions with the way your dog actually rests.
