Why is my dog limping? Causes and when to see a vet
A limp is the body protecting something that hurts, and the causes run from trivial to serious. A dog that is mildly favouring a leg but still using it can often be checked over at home and rested. A dog holding a leg completely off the ground, or dragging its back legs, needs a vet the same day. Here is how to tell what you are looking at.
Check the paw and leg first
Start with the simplest and most common problem: something in the paw. With the dog calm, look between the toes and at the pads for a cut, a torn nail, a thorn, a grass seed, chewing gum or a stone. In summer, a grass seed can work its way in and cause sudden lameness. Feel gently up the leg for heat, swelling or a spot that makes the dog flinch. If your dog is in real pain, stop — a hurting dog may snap even at someone it loves — and let the vet do the handling.
The likely causes
A short-lived limp after hard exercise is usually a sprain or strain, the canine equivalent of a twisted ankle. Other common causes are a paw injury, a torn nail, or a knock. Two bigger ones are worth knowing. A sudden hind-leg limp in a mid-size or large dog is often a cruciate ligament injury in the knee, which usually needs veterinary treatment. A gradual limp that is worse after rest and eases with movement, especially in an older or large dog, is often arthritis or an underlying joint condition such as hip or elbow dysplasia — something a Labrador Retriever or German Shepherd is more prone to. In a long-backed breed like the Dachshund, wobbliness or dragging in the back legs can be a spinal disc problem, which is urgent.
When rest is worth trying
For a mild, intermittent limp in a dog that is otherwise bright, still putting weight on the leg, with nothing obvious stuck in the paw, a couple of days of strict rest is reasonable. That means lead-only toilet breaks, no runs, no jumping on or off furniture, and no stairs or slippery floors. Many minor sprains settle with this alone. Do not give human painkillers to bridge the gap — ibuprofen and paracetamol are toxic to dogs, and masking pain also tempts a dog to overuse an injured leg. If the limp has not clearly improved in about 48 hours, or it gets worse, book a vet.
See a vet now if you notice any of these
Get your dog seen the same day, or straight away out of hours, if it: will not put any weight on the leg at all; has a leg that hangs, looks deformed or is swollen (a possible fracture or dislocation); cried out and then went lame; is dragging, knuckling or wobbling in the back legs, or seems painful along the spine — this can be a disc problem where speed protects the nerves; is limping and also feverish, flat or off its food; or has a limp that lasts more than a couple of days or keeps returning. A leg that is cold and painful with sudden weakness also needs an emergency call.
Common questions
Should I walk my dog if it is limping?
No — cut walks right back. For a mild limp, restrict the dog to short lead-only toilet breaks and stop runs, jumps and stairs for a couple of days, which gives a minor sprain a chance to settle. If the dog won't bear weight at all, or the limp lasts beyond about 48 hours or worsens, see your vet rather than walking it off.
When should I take my limping dog to the vet?
See a vet the same day if your dog won't put any weight on the leg, the leg looks deformed or swollen, it yelped and went lame, it is dragging or wobbly in the back legs, or it is also feverish or unwell. For a mild limp, a vet visit is warranted if two days of rest hasn't clearly helped.
Can I give my dog painkillers for a limp?
Not human ones. Ibuprofen, aspirin and paracetamol can poison dogs, and masking pain encourages a dog to overuse an injured leg and make it worse. If your dog needs pain relief, your vet can prescribe a dog-safe anti-inflammatory at the right dose after checking what is wrong.
Why is my dog suddenly limping on a back leg?
A sudden hind-leg limp in an adult dog is often a cruciate ligament injury in the knee, which usually needs veterinary treatment, but it can also be a sprain, a paw injury or, in some breeds, a slipping kneecap. Dragging or weakness in both back legs is different and more urgent, as it can involve the spine — see a vet promptly.
My dog was limping but seems fine now — do I still need the vet?
If the limp was brief, mild and has fully resolved, and your dog is using the leg normally, you can reasonably keep an eye on it. But limps that come and go can be an early sign of a joint or ligament problem, so if it returns, lasts, or your dog is favouring the leg during or after exercise, get it checked.
