When you're the one lifting
When a dog can't get its back end up on its own, you become the mobility aid. The right harness protects your dog's dignity and your back — here's how to choose by where the weakness actually is.
The hardest stretch of a dog's aging is when it can't stand or bear weight on its own and someone has to help — usually the owner, often several times a day, sometimes a large dog and an older person. The gear that helps is not one thing. A dog that's weak only in the back end needs a rear-support sling or harness that lifts the hips while the front legs still work. A dog that's unsteady all over needs a full-body harness with handles front and back. A dog that has lost a back end entirely may be ready for a wheelchair. We map each aid to the specific weakness it's for, so you buy the one that fits your dog rather than the one with the best listing photo.

Guide
The four ways a support harness fails to fit an old dog, how to tell which one you have, and which are fixable without buying again.
Match the aid to where the weakness actually is. Buying the wrong category is the most common mistake here.
If your dog's front legs still work but the back end is giving out — struggling to stand, knuckling, slipping behind — a rear-support sling lifts the hips while the dog powers along with its front legs. A long-handled sling lets you stand upright behind the dog, which matters a great deal for your own back over weeks of daily help. See our rear-leg support picks.
A dog that's weak or wobbly in front as well as back needs handles at both ends so you can steady or lift the whole dog. Full-body harnesses cost more and take longer to fit, but for a dog that's genuinely unsteady they're the safer, kinder tool.
When a dog can no longer bear weight on its back legs at all, a rear-support cart can give it its walks back. This is a decision to make with your vet — a cart is right for some dogs and not others, and fit matters enormously. An adjustable cart forgives a growing or changing dog; a budget cart gets a confirmed case rolling for less.
Support the hips and chest, not the belly or the legs; let the harness do the lifting, not your back; and keep the dog's spine level. A good sling with a handle placed over the hips is designed to make this posture natural.

Questions
The honest version
We don't run a testing lab. We compile the specs that actually decide whether a product helps a senior dog, score them against a published rubric, verify prices live from Amazon, and tell you plainly who each pick is not for. When a question is medical, we say so and point you to your vet. How we're funded.
