Knuckling in Dogs: What It Means and How to Help

6 min read Vet-informed guidance

Knuckling is when a dog walks on the top of their paw instead of the pad, or the paw drags and scuffs along the ground. It often points to a problem with the nerves or mobility, so it’s worth a vet check — but there’s also plenty you can do to help.

What causes knuckling?

Knuckling happens when the signals telling the paw to position itself correctly aren’t getting through properly, or the leg is too weak to lift the paw fully. Causes range from nerve and spinal conditions to arthritis, injury and general weakness, especially in older dogs.

Signs to look for

It can be subtle at first.

The paw turning under or dragging along the ground
Scuffed, worn nails on the affected foot
Grazes or sores on the top of the paw
Stumbling or an uneven, scuffing gait

How to help

Protecting the paw and supporting the leg are the priorities while the cause is investigated.

Anti-knuckling boots or socks to protect dragging paws
A support harness to assist movement
Non-slip flooring to give better grip
Gentle, regular exercise and physiotherapy to maintain strength
Keep nails trimmed and check paws daily for grazes

When to see your vet. Have knuckling checked by your vet, especially if it comes on suddenly or affects the back legs — it can be a sign of a treatable nerve or spinal condition that benefits from early attention.
