Dog limping: causes, how to check the paw and when to worry

Your dog bolts across the park like always and suddenly holds up a back leg. Or it gets up stiff in the morning and takes a few steps to walk normally. If your dog is limping, something almost always hurts, even if your dog isn't crying or whining. Dogs are very good at hiding pain.

The good news is that many limps have a simple cause you can find yourself by checking the paw. This guide covers how to tell which leg hurts and how badly, how to examine it safely, the most common causes by age and type of limp, what to do at home and when to head to the vet without waiting.

How to tell which leg hurts and how bad the limp is

Sometimes it isn't obvious which leg is the problem. Walk your dog slowly in a straight line on a flat surface and watch from the front, the side and behind:

• Front leg: your dog's head bobs up when the sore leg hits the ground and drops when the good leg lands.
• Back leg: the hip on the sore side rises and falls more than the other, and that leg takes shorter steps.
• Sitting: if your dog kicks one back leg out to the side instead of tucking it under, suspect the knee.

A slow-motion video on your phone helps both you and your vet, because many dogs limp less in the exam room thanks to adrenaline.

How to check your dog's leg safely

Even the sweetest dog can bite when you touch a painful spot. Go slowly, have a second person hold and reassure your dog and, if your dog is already used to one, use a basket muzzle, which still allows panting. Don't use a tight or improvised muzzle on a dog that's panting hard, vomiting or struggling to breathe.

1. Pick a well-lit spot and start with the healthy leg, both for comparison and to help your dog relax.
2. Look at the pads: cuts, cracks, burns, blisters or anything stuck in them.
3. Spread the toes: look for foxtails, wounds, lumps, red areas or rust-colored fur from licking.
4. Check the nails, including the dewclaw: broken, torn, overgrown or curling into the skin.
5. Work your way up the leg, feeling gently and comparing with the other side for heat, swelling or lumps.
6. Bend and straighten each joint very slowly. Stop at the first sign of pain: pulling away, turning toward you, tensing up, growling or yelping.

Don't force anything. If you can't find the cause or your dog won't let you, your vet can examine it, with sedation if needed.

Paw problems: pads, foxtails and nails

These are the most common causes of a sudden limp and often the easiest to fix:

• Cuts and wounds from glass, rocks or metal. Paw pads bleed a lot, even from small cuts.
• Burns from hot pavement or sand. Press the back of your hand on the ground: if you can't hold it there for seven seconds, it's too hot for paws. Our dog paw care guide explains how to protect pads in summer heat and winter salt.
• Foxtails lodged between the toes, especially from late spring through summer in the West. Dogs lick the spot constantly, and a red, sometimes oozing bump appears. Learn more about foxtails in dogs.
• Broken, overgrown or ingrown nails and dewclaws. Long nails change how the foot lands and can cause soreness; here's how to trim dog nails step by step.
• Insect stings, cysts or infected bumps between the toes.

Muscle and ligament injuries

• Sprains and strains. From a misstep, a jump or rough play. A mild to moderate limp that improves within a few days of rest. If there's no improvement in 48 hours, something else may be going on.
• Torn cranial cruciate ligament (often called a torn ACL). One of the most common causes of back-leg lameness in dogs. Unlike in people, it usually results from gradual degeneration of the ligament, which finally tears during an everyday movement. Expect a sudden back-leg limp, often touching down only with the toes, and sitting with that leg kicked out. It's more common in medium and large dogs and in overweight dogs, and some go on to injure the other knee as well.
• Luxating patella. The kneecap slips out of place now and then. It's typical of small breeds such as Yorkshire terriers, Chihuahuas, Pomeranians and toy poodles: the dog skips for a few steps with one back leg held up, then walks normally.

Dysplasia and growth-related problems

In puppies and young dogs of medium and large breeds, a limp can come from how bones and joints develop:

• Hip dysplasia. The hip joint doesn't fit together properly. Watch for trouble getting up, low stamina, "bunny hopping" with both back legs together when running or a back-leg limp. We cover it in depth in hip dysplasia in dogs.
• Elbow dysplasia. Limping on one or both front legs in young dogs of breeds like Labradors, golden retrievers, German shepherds and Rottweilers.
• Panosteitis. Painful inflammation of the long bones in growing large-breed dogs, usually before 18 months of age. The limp shifts from leg to leg and typically resolves once growth is complete, but the pain still needs treatment.

Arthritis and limping in older dogs

Osteoarthritis is the most common cause of chronic limping in senior dogs, though it can start earlier as a result of dysplasia or an old injury. Typical clues:

• Stiffness when getting up that eases after a few minutes of walking.
• Worse in cold, damp weather or after a big day of activity.
• Trouble with stairs or jumping into the car or onto the couch.
• Walking more slowly or lagging behind on walks.

Many owners chalk it up to "just getting old," when it's actually treatable pain. Learn the subtle signs your dog is in pain. Keeping your dog at a healthy weight is one of the most effective ways to take pressure off sore joints.

Other causes: infections, the spine and fractures

• Tick-borne diseases such as Lyme disease and anaplasmosis can inflame several joints at once, causing a limp that shifts between legs, fever or lethargy. If your dog has had ticks, tell your vet; here's how to prevent and remove ticks on dogs.
• Spinal problems, such as a slipped disc: dragging a leg, knuckling over onto the top of the paw, wobbling or back pain. They're more common in dachshunds, French bulldogs and beagles and can be emergencies.
• Fractures and dislocations after being hit by a car, a fall or another accident: no weight on the leg, swelling, deformity or an odd angle.

Quick guide: what different limps can mean

What to do at home (and what not to do)

If the limp is mild, there's no visible wound and your dog seems fine otherwise:

1. Strict rest for 24–48 hours: short leash walks for bathroom breaks only, no running, jumping on furniture or stairs.
2. Add traction: put rugs or runners on slippery hardwood or tile floors.
3. Rinse small wounds with clean water or saline and keep your dog from licking them.
4. Watch how it progresses: if there's no clear improvement in 48 hours, or it gets worse, book a vet visit.

Avoid massaging or stretching a painful leg, and don't apply heat or ice unless your vet recommends it. This guide can't replace a hands-on exam of the bones, ligaments and joints.

What your vet will do

Your vet will watch your dog walk, feel the entire leg and run specific orthopedic tests, such as checks for knee instability in cruciate tears. Depending on the findings, the next step may be X-rays (often with sedation so your dog stays relaxed), joint fluid analysis, tests for infectious diseases or a CT scan.

Treatment depends on the cause: wound care and foreign body removal, controlled rest, veterinary pain medication, physical therapy and rehab, weight management or surgery for problems like cruciate tears, severe luxating patellas or fractures.

How to prevent injuries and limping

• Keep your dog lean: extra pounds multiply the load on every joint.
• Exercise consistently, ideally daily rather than all on the weekend, and warm up with a few minutes of walking before hard play.
• With large-breed puppies, avoid repetitive jumping and forced exercise while they're growing.
• Check paws after hikes and keep nails short.
• Avoid hot pavement in summer and slippery floors at home.

Frequently asked questions

How long can a mild limp last in a dog?

A minor strain or bump usually improves noticeably within 24–48 hours of rest and is gone within a few days. If there's no improvement after 48 hours, the limp comes and goes for weeks or it gets worse after exercise, it's time to look for the cause with your vet, because injuries like a cruciate tear can seem minor at first.

My dog is limping but not crying. Is it in pain?

Almost certainly, yes. Limping is how a dog protects a body part that hurts when it bears weight. Many dogs never whimper, and some keep playing enthusiastically because excitement masks the pain for a while. Not complaining doesn't mean your dog doesn't need help, especially if the limp lasts more than a couple of days.

Why does my dog limp only after lying down?

A limp that shows up after rest and fades after a few minutes of walking is classic for arthritis, especially in senior dogs or those with a history of dysplasia. Joints stiffen up during rest and take time to loosen. It's treatable with pain management, a healthy weight, moderate regular exercise, a supportive bed and floors that aren't slippery.

Can a torn ACL in a dog heal without surgery?

In small, lightweight dogs, strict rest and rehab can improve the limp in some cases. In medium and large dogs, surgery generally gives better results because it stabilizes the knee. Either way, the knee tends to develop arthritis over time, so weight control and physical therapy matter with or without surgery.

Is it normal for a puppy to limp after playing?

Puppies tumble constantly, and a mild limp that disappears within a few hours usually isn't a concern. But their bones are still growing, and some injuries affect the growth plates, which are delicate. If the limp lasts more than a day, keeps coming back or moves from leg to leg, have your vet take a look.
