Sacrocaudal Dysgenesis in Dogs

What to Watch For

Dogs normally show no ill effects related to this defect. Those who suffer neurologic deficits, however, will present very early on in life (within the first few weeks) with difficulty walking in the hind limbs and/or incontinence of feces or urine or both. Most neurologically affected puppies are euthanized.

It is sometimes associated with spina bifida.

Diagnosis of Sacrocaudal Dysgenesis in Dogs

Diagnosis of sacrocaudal dysgenesis is often suspected based on the history and physical examination.

Additional diagnostic tests recommended includes imaging (usually with X-rays but also with a myelogram, CT scan and/or MRI).

Treatment of Sacrocaudal Dysgenesis in Dogs

There is no known treatment for this congenital disease. It is possible, however, to adapt affected animals to carts that will allow for ambulation in the case of severe paraplegia. Any related incontinence, however, is not considered treatable and is the most common cause for euthanasia related to sacrocaudal dysgenesis.

Veterinary Cost Associated with Sacrocaudal Dysgenesis

The cost of treatment depends on the lengths an owner will go to in accommodating a neurologically abnormal animal to life in a paraplegic’s cart or other approach. Diagnosis is typically very inexpensive unless major imaging work is performed.

Prevention of Sacrocaudal Dysgenesis in Dogs

Curbing the breeding of any first-degree relatives to affected animals is a must. Parents and siblings should not be bred. Ideally, animals should not be bred for tail-lessness. This trait is fraught with unintended spinal consequences as mentioned above.
