IVDD in French Bulldogs & Other At-Risk Breeds

The headline breed to know about, beyond the dachshund, is the French bulldog, because its risk is both high and rising. In a large study of IVDD across many breeds, the French bulldog carried the highest adjusted odds of any purebred dog, with around twenty-one times the odds of disc disease compared with a typical dog. To put how central this is to the breed, disc disease is the single most common neurological disorder seen in French bulldogs, accounting for something like forty-five percent of their neurological cases. French bulldogs also tend to be affected young, with one of the earliest average ages at diagnosis of any breed, often under five years old.

There is a further point Frenchie owners genuinely need to know, because it is both striking and under-publicised: recurrence is common. In a study of French bulldogs that had surgery for a first IVDD episode, more than half, around fifty-three percent, went on to have a recurrence, with about half of those recurrences happening within the first year, and young dogs particularly prone to a further episode in the neck. In other words, an IVDD episode in a Frenchie is quite often not a one-off, which is important to factor into both expectations and insurance.

What makes all this especially important is the breed's explosive rise in popularity. As French bulldogs have become one of the most popular breeds, the sheer number of them means disc disease in the breed is being seen more and more, and many new Frenchie owners have no idea their fashionable companion carries a back-problem risk rivalling, indeed exceeding, the dachshund's. So if you have a French bulldog, this is genuinely worth knowing: yours is, statistically, among the most IVDD-prone breeds there is, the disease is the commonest neurological problem in the breed, and recurrence is more likely than not. The awareness that a dachshund owner would have is just as important for you.

The French bulldog and the dachshund lead the field, but a number of other breeds carry a clearly raised risk, and it is worth knowing the wider line-up so that owners of these dogs are alert too. Breeds repeatedly identified as chondrodystrophic and at increased IVDD risk include the beagle, the Pembroke Welsh corgi, the cocker spaniel, the basset hound, the shih tzu, the Cavalier King Charles spaniel, the pug, and the bichon frise, among others. You will notice a pattern in that list, and it is not a coincidence: these are mostly the short-legged, long-bodied dogs, the breeds with that distinctive low-slung, dwarfed build. That shared shape is the visible clue to a shared underlying cause, which is the key to the whole picture.

It is also worth noting two more general risk factors the research has identified, because they apply across breeds: being a toy or small dog, and being overweight, are both linked to higher odds of IVDD, while more daily activity is linked to lower odds. So whatever your breed, keeping your dog lean and appropriately active is sensible, protective advice.

If your breed is on that list, the message is not alarm but awareness: a genuinely raised risk that is worth taking seriously, knowing the warning signs for, and factoring into how you care for your dog, exactly as a dachshund owner would. And if your breed is not on it, no list like this is ever complete, so a raised risk can exist in other breeds too, and the warning signs are worth knowing for any dog.

Here is what ties all these breeds together, and it is the same story we tell in full in our article on dachshunds, so I will keep it brief here and point you there for the detail. The common thread is a genetic feature these breeds share, the same one responsible for their characteristic short legs. A particular gene variant, an FGF4 retrogene on chromosome 12, gives these breeds their dwarfed, short-legged build, and in the very same stroke causes their intervertebral discs to degenerate and calcify abnormally early in life.

This is why the at-risk breeds so often share that low-slung shape: the short legs and the disc disease come from the same genetic source, so the body shape is, in effect, a visible flag for the disc risk that travels with it. The proper term for this build is chondrodystrophic, meaning the short-legged, long-bodied conformation produced by that gene, and it is the chondrodystrophic breeds that dominate the IVDD risk list. The crucial point, which our dachshund guide explains more fully, is that it is the gene, not simply the long back, that drives the disc problem; the discs of these breeds are programmed to age early regardless. So when you look at a French bulldog or a corgi or a basset hound and see that distinctive shape, you are looking at the outward sign of the same genetic predisposition, and that is why these particular breeds cluster at the top of the risk list together.

One useful nuance for owners of these breeds is that disc disease does not always strike in the same place. In many dogs, dachshunds classically, the problem most often occurs in the middle of the back, the thoracolumbar spine. But some breeds are relatively more prone to disc disease in the neck, the cervical spine, and this includes French bulldogs and beagles. French bulldogs in particular can be predisposed to spinal problems linked to malformations in their vertebrae, a consequence of the same selective breeding that shapes the breed, and as we saw, their recurrences often strike in the neck.

Why does this matter to you? Because neck disc disease can look a little different from the classic back problem, often dominated by severe pain, a low, stiff head carriage, a reluctance to lift or turn the head, and sometimes wobbliness affecting all four legs rather than just the back ones. So if you have a Frenchie or a beagle, it is worth knowing that a disc problem might show up as neck pain and all-four-limb signs, not only as the back-leg weakness people associate with IVDD. Whatever form it takes, the urgency is the same, and our guide to the red flags covers the warning signs to act on across both the neck and the back.

So, to bring it together: the dachshund may be the famous face of IVDD, but the French bulldog now tops the risk list, is being seen more every year, has disc disease as its commonest neurological problem, and tends to suffer recurrences; and a whole group of short-legged breeds, beagles, corgis, cocker spaniels, basset hounds, and others, share a genuinely raised risk through the same genetics that gives them their distinctive shape. If you own one of these breeds, the practical takeaway is simple and empowering: know that your dog is at raised risk, learn the warning signs for both back and neck disease so you can act fast if they ever appear, and care for your dog with that awareness, much as our dachshund guide advises, keeping them lean, avoiding repetitive jarring jumps, walking on a harness rather than a collar, and being alert. And if you are thinking about the longer view, our guide to breeding and the genetics of IVDD looks at how the same science that explains this shared risk is beginning to offer ways to reduce it in future generations.
