Senior Dog Mobility Gear, Sized Correctly

Dog harness and ramp sizes aren't standardized. A "medium" from one brand can be a "large" from another, because brands measure differently — some by weight, some by chest girth, some by both. This site cross-references the published size charts from major mobility brands and calculates two things: which harness type fits your dog's condition and support needs, and how long a ramp needs to be for a given rise, based on the angle guidance used across veterinary mobility resources. This site doesn't publish product reviews.

What this isn't

A diagnosis comes from your vet. This tool narrows the shopping list after that — it doesn't replace an exam, and it doesn't cover wheelchairs.
