If your dog is limping a little but still putting weight on the leg, eating and acting normal, you can check the paw at home and rest them for 24-48 hours. But see a vet today if your dog won't put any weight on the leg, if you see a deformity, a deep or heavily bleeding wound or fast swelling, or if the limp started after a fall, a fight or being hit by a car. And if the limp lasts more than a couple of days or keeps coming back, make an appointment.
Most common causes
When the limp starts suddenly:
- A torn or broken nail: very painful and very common.
- A cut or something stuck in the paw pad: glass, a stone or a foxtail (a barbed grass seed) between the toes. See foxtails in dogs.
- A sprain or strain of a muscle or ligament, for example from running or jumping.
- A torn cruciate ligament (the dog version of an ACL tear): the most common cause of hind-leg lameness in middle-aged dogs.
- A fracture or dislocation after a fall, a fight or a car accident.
When the limp comes on slowly or comes and goes:
- Arthritis, especially in older dogs.
- A slipping kneecap (patellar luxation): the dog skips a few steps with one back leg held up. It's typical of small breeds.
- Hip or elbow dysplasia, more common in large breeds.
- Cruciate ligament disease, which often starts as a mild limp that slowly gets worse.
- Nerve problems or, less often, bone tumors.
- Tick-borne diseases like Lyme disease can cause a limp that shifts from leg to leg: see ticks on dogs.
How to check the paw at home
If your dog is calm and lets you, in good light:
- Look at the pads and between the toes for cuts, foxtails, glass or stones.
- Check the nails: a torn or bleeding nail is easy to spot.
- Gently feel from the toes upward, comparing with the other leg, for swollen, warm or painful areas.
- Stop if your dog cries or tries to bite: even the gentlest dog may bite when in pain.
If you find a foxtail that doesn't come out easily, don't dig for it: take your dog to the vet, because foxtails can work their way under the skin.
When it's urgent
Go to the vet today if:
- Your dog won't put any weight on the leg.
- The leg looks deformed, is at an odd angle or you can see bone.
- There's a deep wound or one that bleeds a lot.
- The leg swells quickly or feels very hot.
- They've been hit by a car, fallen or been in a fight, even if they seem fine.
- They cry in pain, seem very down or have a fever.
Make an appointment within the next few days if:
- The limp doesn't improve after 24-48 hours of rest.
- It comes and goes or slowly gets worse.
- Your dog has trouble getting up, climbing stairs or jumping on the couch.
What you can do in the meantime
- Rest: short leash walks for bathroom breaks only. No running, jumping or fetch.
- Don't give human pain relievers. Ibuprofen (Advil), naproxen (Aleve), acetaminophen (Tylenol) and aspirin can be very dangerous for dogs. If your dog is in pain, your vet can prescribe an anti-inflammatory made for dogs.
- If a broken nail is bleeding, press gently with clean gauze and take your dog to the clinic.
What the vet will do
Your vet will do an orthopedic exam: watch your dog walk, feel the leg and move the joints to find the pain. The usual next step is X-rays, which show fractures, arthritis, dysplasia or joint inflammation. Sometimes they'll recommend bloodwork or a joint fluid test.
Treatment depends on the cause: from rest and anti-inflammatories for a sprain to surgery for a torn cruciate ligament, a severe slipping kneecap or a fracture.
| Item | Typical US cost |
|---|---|
| Vet exam | $56-$129 |
| X-rays (2-3 views) | about $172 |
| Cruciate ligament surgery and medication | $5,439 (average Trupanion claim) |
| Slipping kneecap surgery and pain medication | $4,012 (average Trupanion claim) |
| Fractured pelvis after a car accident | $3,717 (average Trupanion claim) |

Frequently asked questions
My dog is limping but not crying. Is it serious?
Not always, but not crying doesn't mean it doesn't hurt: dogs are good at hiding pain. If the limp lasts more than a day or two, or keeps coming back, have your vet check it.
Can a torn cruciate ligament heal without surgery?
Pain medication helps, but the knee stays unstable and tends to keep hurting and wearing down. That's why surgery is often recommended, especially for medium and large dogs. Your vet will explain the options based on your dog's weight, age and activity level.
Why does my dog limp in the morning and then it goes away?
Stiffness that improves with movement is typical of arthritis, especially in older dogs. It can be treated, so bring it up with your vet.
