Spinal Cord Stroke in Dogs

Large breeds, such as the Irish wolfhound pictured here, are at greater risk for spinal cord strokes.

Spinal cord strokes can occur in all dogs, but such strokes more typically affect larger canines and middle-aged dogs. Strokes of the spinal cord tend to come on during exercise or play and can result in the dog losing the use of one or more limbs. Dogs who have had a stroke may respond to some physical rehabilitation and can live productive lives with caring owners.

History

In the past, veterinarians believed that spinal cord strokes did not occur in dogs. After examining dogs exhibiting stroke symptoms with the use of human-caliber medical equipment, it has been determined that canines are at risk for strokes of the spine, according to Anne Chauvet, D.V.M., of Veterinary Neuro Services in Sarasota, Fla.

Identification

A spinal cord stroke is called a fibrocartilaginous embolism. This type of stroke occurs in humans, pigs, dogs, cats and horses. Typically, blood flow to the leg is impeded due to blockage from a plug made of cartilage tissue.

Effects

Mar Vista Veterinarians reports that dogs experiencing a spinal cord stroke may demonstrate paralysis in a hind leg. After the occurrence of a spinal cord stroke, a partial recovery is possible. Some dogs become incontinent and remain at risk for future strokes. Effects vary depending upon the severity of the stroke and the nerves affected.

Prevention/Solution

With the help of a veterinarian, you can determine whether your dog is at risk for a spinal cord stroke. The vet can measure your dog's blood pressure. If the blood pressure is found to be high, the vet will institute changes in diet and exercise and may prescribe amlodipine, an anti-hypertensive, or aspirin, reports Dr. Chauvet.

Diagnosis

A veterinarian can determine whether a spinal cord stroke occurred by ordering a diagnostic test known as a myelogram to check for swelling indicative of a spinal cord stroke. She may also take a spinal fluid sample.

Warning

If your pet suddenly loses the use of his legs but does not respond to pain, it is possible that he has suffered a spinal cord stroke. Treat this as an emergency situation and take him to the veterinarian immediately for diagnosis and treatment.
