The miniature dachshund is the classically affected breed, with more than 20% developing IVDD, with the shih tzu, lhasa apso, beagle, corgi, cocker spaniel, and pekingese breeds also affected. The genes produce the dwarfism necessary for these breeds’ unique looks, but also cause abnormal cartilage and bone development that predisposes them to disc degeneration. Hansen type I - This IVDD type has been linked to specific genes in dog breeds with short legs.Any pet can develop either type, but small-breed pets typically develop type I, while larger breeds most often develop type II. IVDD is generally classified into two types-Hansen types I and II. Degraded spinal discs can herniate with relatively little force, such as a cough, sneeze, or misstep. The disease can also cause discs to rupture and herniate, forcing disc tissue into the spinal canal and placing pressure on important nerves. Most pets develop some disc degeneration during the normal aging process, but IVDD accelerates changes. ![]() In IVDD, the discs dry out, harden, flatten, and no longer absorb shock effectively, which can contribute to spinal stiffness and arthritis. Together, the disc materials absorb shock between spinal bones (i.e., vertebrae) and allow smooth, flexible movement. Intervertebral discs consist of two layers-a strong outer fibrous layer, and gel-like inner core. IVDD can be devastating, so Haskell Valley Veterinary Clinic wants to ensure you can recognize risk factors and early signs to provide for the best treatment outcomes in affected pets. What do dachshunds, pekingese, and beagles have in common? They’re several of many dog breeds at higher risk for developing intervertebral disc disease (IVDD), which far more commonly affects dogs with short legs and long backs because of their genetic makeup, but can occur in any dog. ![]()
