Sudden Back Pain or Weak Legs in a Dog: What to Do

New weakness, dragging a leg or loss of the ability to stand can accompany a spinal problem in a dog. Call an emergency veterinary service right away if your dog cannot walk, is getting weaker or is in severe pain. A dog that has suddenly become painful but can still walk also needs prompt advice. Keep movement to a minimum while you arrange care.

The American College of Veterinary Surgeons describes intervertebral disc disease as one possible cause. A dog’s exam helps establish where the problem may be and what comes next. A hunched posture or reluctance to move is useful information, but it cannot confirm a disc problem from home.

Describe what changed without making the dog demonstrate it

Tell the clinic when the dog last moved normally and what you saw next: crying on a step, walking unsteadily, placing a paw awkwardly or being unable to rise. Mention whether your dog has urinated since the change and whether you saw a fall or other injury. If a video already exists, save it. Do not take the dog up stairs, press on the back or pinch a toe to get more information.

Ask how to move the dog from where they are. Describe the dog’s size, whether you have another adult to help and whether there are steps to the car. Keep other animals away, prevent jumping, and follow the clinic’s advice on a carrier or safe support. Tell the staff if pain makes your dog likely to bite when lifted. This is a handling detail they can plan for.

Keep the diagnosis separate from the home instructions

Depending on the findings, treatment can involve prescribed movement restriction and medication or a referral for imaging or surgery. If you return home with restrictions, ask what is allowed for bathroom breaks, where your dog should rest and which change means coming back immediately. Get that answer in writing; “rest” can mean different things to people in the same house.

Do not start leftover or human pain relievers; our pain medicine guide explains why a call comes first. Once you have instructions, give everyone in the house the same route for toileting, the same lifting rules and the number to call if your dog gets worse.
