Hemivertebrae is an inherited birth defect in which one or more of the vertebrae are malformed or fused. The vertebrae are the bones that make up the spine, and hemivertebrae can occur in more than one location on the spine. In breeds such as Bulldogs, it is actually hemivertebrae that creates the desired curly tail configuration. However, in other cases, this malformation or fusing may cause the spine to have an unnatural angle which can pinch nerves and impact muscle control.

Symptoms of hemivertebrae depend upon which portion(s) of the spine is impacted. These symptoms include spinal pain, weakness, hind leg pain, hind leg paralysis, urinary incontinence and fecal incontinence.

This is an inherited condition.

Your vet will take x-rays of your dog's vertebrae to make a diagnosis.

Most cases of hemivertebrae are mild and require no treatment. However, more severe cases will require surgery to stabilize the spine and relieve nerve pressure.

Since it is an inherited condition, afflicted dogs in breeds in which hemivertebrae is not the norm should not be bred. Likewise, you should not acquire a dog with a family history of this condition.

No, you cannot develop hemivertebrae from your dog.
