Back and Spine Issues in Bichon Frises: Understanding Disc Disease Properly

Veterinary medicine separates disc disease into Hansen type I and Hansen type II. Understanding which one you are reading about changes almost everything, including whether the breed association applies to your dog at all.

The dwarfing gene that produces the long-and-low body plan is what predisposes a breed to early disc calcification and type I rupture. The Bichon Frise does not carry that body plan. It is a proportionate, roughly square small dog of 9 to 12 inches with normal limb length, and disc disease is not among its documented health issues.

So the risk profile is not zero, because no dog's is, but it is not the dachshund's risk either. A Bichon that develops spinal cord signs is more likely doing so in old age, more likely by the gradual type II route, and more likely to have arthritis or a hind limb problem as the actual explanation.

That last point deserves emphasis. Patellar luxation is documented in this breed, and the picture it produces, an intermittently skipping hind leg, is misread as a spinal problem constantly.

The distinguishing question is coordination. A dog with a knee problem knows exactly where its foot is; it just cannot use the leg for a moment. A dog with spinal cord compression has lost track of where its feet are, so it scuffs, knuckles, crosses its back legs and wears the tops of its hind toenails flat.

If you think your Bichon has back/spine issues, the plan is three steps: write down what you have seen and when it started, book a veterinary appointment rather than waiting for the next flare, and take video of the behaviour or symptom before you go — the thing you are worried about rarely happens in the consulting room. Screening in the parents covers skin allergies, patellar luxation, bladder stones.

What the vet visit should produce is a diagnosis and a written plan, not just reassurance: what is being ruled out, what the monitoring interval is, and which signs mean you come back sooner. Ask what the treatment costs across a year rather than per visit, because that is the number that decides whether you are managing this condition or reacting to it.

Between appointments, keep a short log — dates, what you saw, what changed. It is the single most useful thing an owner brings to a follow-up, and for back/spine issues it is often what separates a clear pattern from a guess.
