"Dog limping front leg" and "dog limping back leg" are searched 3,500 times a month in the UK, and the breed version adds three words: "but not in pain". This page gives the two published thresholds, which differ, says what a front-leg limp and a back-leg limp tend to be in a French Bulldog, and points to the one thing that does not get two days' grace in this breed, which is the spine. No verdict; the phone call does that.
Two thresholds, and they differ
The Kennel Club: see a vet if the dog is "unable to put any weight on their limb, or they're in pain", or the "limb looks visibly swollen or deformed"; a mild injury "may just need to rest for a day or so, and let nature take its course", and "If the limping continues for more than 2 days, it's important to visit your vet." The PDSA sets the bar lower: "Contact your vet if you notice your dog is limping or appears stiff. Contact your vet immediately if your dog is in severe pain, is unable to put a leg down or has a serious wound." Its reason is the one that matters for this breed: "It is important to take your dog to the vets even if their problem appears minor - some dogs are very good at hiding pain from their owners." "Limping but not in pain" is a contradiction a vet hears every day; a dog does not limp for fun.
Front leg
A front-leg limp in a young French Bulldog with no history is more often the foot than the shoulder: a torn nail, a grass seed, a cut pad, or the breed's interdigital cyst between the toes, which is red, swollen and licked at. Look at the foot before anything else, pad by pad and between the toes. A shoulder or elbow limp that shows after rest and eases with movement in an older dog is the pattern of arthritis, which in UK dogs is diagnosed at a median age of 10.5 and is fifty-four times as likely over twelve as under three. The Kennel Club's two-day rule is written for this kind of limp. The exception is a front leg the dog will not put down at all, which is the same day in any breed.
Back leg
A back-leg limp in this breed has three usual owners, and two of them are on this site because the breed is prone to them. A skipping limp, a leg held up for a few strides then put down normally, is the picture of a luxating kneecap. A stiff, bunny-hopping gait, reluctance to rise, and a dog that sits oddly is the hip. And a back-leg limp with anything else, a wobble, a hunched back, a yelp when picked up, a reluctance to jump, feet that scuff or knuckle, is the spine, and the spine is the reason this page exists.
The spine does not get two days
Disc disease arrives in French Bulldogs younger than in any breed it was compared with, and the risk of a second episode after the first is real. The general rest-then-see rule is the wrong rule for it, because a disc that is pressing on the cord can go from a limp to paralysis in hours, and the surgical window is measured in hours too. The early-signs check on the IVDD page is eight signs with two marked red, and it says which of them mean today. If the back leg is the one limping, do that check before you decide anything else. The ramp is for afterwards.
Home, for the mild ones
For the limp the Kennel Club's rule applies to, a mild one in a dog bearing weight with no swelling: rest, meaning no walks, no stairs, no sofa, for the day or so it allows, and a look at the foot. Nothing from the human medicine cabinet; the dog's painkillers are prescribed for a reason and the wrong ones are poisons. If it is not better in two days by the Kennel Club's clock, or was ever not bearing weight, or the PDSA's "you know your dog best" says something is wrong, it is the vet.
Have ready for the call
- Which leg, and whether the dog will put weight on it.
- When it started, and what happened just before: a jump, a fall, a game, nothing.
- Whether it is constant or a skip, and whether it is worse after rest or after exercise.
- What the foot looks like between the toes and on the pads.
- For a back leg: whether the dog can climb a step, whether the feet drag or turn over, whether the back is hunched, and whether it yelped when lifted.
- A short video of the dog walking away from you and towards you.
What this page is not
A verdict. The thresholds are the Kennel Club's and the PDSA's own words and they differ, so both are here. The breed lines are the site's sourced pages on the kneecap, the hip, the cysts and the spine. The arthritis figures are from the VetCompass osteoarthritis study of 455,557 dogs and are not breed-specific.
Common questions
My French Bulldog is limping on a front leg. What is it likely to be?
The foot, more often than the shoulder, in a young dog with no history: a torn nail, a cut pad, a grass seed, or an interdigital cyst between the toes. Look there first. The Kennel Club allows a day or so of rest for a mild limp and says the vet if it passes two days; the PDSA says contact the vet on noticing, and immediately if the dog will not put the leg down. A dog not bearing weight is the same day either way.
My French Bulldog is limping on a back leg. Is it the spine?
Treat it as the spine until the early-signs check on the IVDD page says otherwise. A back-leg limp with a wobble, a hunched back, a yelp when lifted, a reluctance to jump or feet that scuff is a today call in this breed; a disc can go from a limp to paralysis in hours. A skipping limp is more often the kneecap, a stiff bunny-hop the hips, and both have their own pages.
My French Bulldog is limping but not in pain. Do I still need the vet?
A dog does not limp for fun; the PDSA's line is that some dogs are very good at hiding pain from their owners, and it says contact the vet if you notice limping or stiffness at all. The Kennel Club gives a milder limp a day or so of rest and two days before the vet. If the dog will not put the leg down, is swollen, or it is the back leg with any other sign, it is not a two-day limp.
How long should I wait before taking a limping dog to the vet?
The Kennel Club says rest for a day or so and the vet if it continues past two days, and the same day if the dog cannot bear weight, is in pain, or the leg is swollen or deformed. The PDSA does not give a waiting period: contact the vet on noticing, immediately for severe pain, a leg that will not go down or a serious wound. In this breed a back-leg limp with any other sign skips the wait.
My French Bulldog jumped off the sofa and is limping.
Look at the leg and the back, not just the leg. A jump down is the load the breed's spine tolerates worst, and a limp after one that comes with a hunch, a yelp when lifted, a wobble or reluctance to move is a today call by the IVDD page's check. A plain limp in a dog that is otherwise itself, bearing weight, with no swelling, is the Kennel Club's rest-a-day limp. Either way, the sofa gets a ramp afterwards.
Can I give my French Bulldog painkillers for a limp?
Not from the human medicine cabinet. Anti-inflammatories for dogs are prescribed by weight and after the vet has decided what is being treated, and the wrong ones are poisons. Rest, no stairs or sofa, a look at the foot, and the vet by the thresholds above.
