SM in dogs stands for Syringomyelia, a serious neurological condition where fluid-filled cavities (syrinxes) form in the spinal cord, often due to Chiari-like malformation (skull too small for the brain), causing severe neck/shoulder pain, phantom scratching, sensitivity to touch, behavioral changes, and potential limb weakness, commonly seen in Cavalier King Charles Spaniels and Brussels Griffons.

What causes SM in dogs?

Disruption of this normal free flow of CSF from the brain to the spinal column is one important cause of syringomyelia in animals (including humans). The most common cause of this obstruction is a hindbrain herniation referred to, in dogs, as Chiari-like malformation.

What does it mean when a dog sm?

Is syringomyelia fatal in dogs?

Unlike mitral valve disease, Chiari-like malformation and syringomyelia (CM/SM) are rarely fatal. However, this doesn't lessen the impact of the condition, as it can be extremely painful, and many dogs are eventually euthanized due to uncontrolled pain.

Syringomyelia and Chiari Malformation Symptoms in Dogs

What age do dogs get syringomyelia?

Cavaliers with syringomyelia usually have their first signs between 6 months and 3 years of age; however, dogs of any age may be presented. Progression of the disease is very variable. Some dogs have the tendency to scratch with mild pain only and other neurological signs never, or very slowly, develop.

What are the first signs of syringomyelia?

Early syringomyelia symptoms often appear slowly and include a loss of pain/temperature sensation (especially in a "cape-like" pattern on shoulders/arms), headaches, numbness, tingling, muscle weakness/wasting, and stiffness, often starting in the neck, shoulders, arms, or hands, though leg issues, balance problems, and scoliosis can also occur.

What dog breeds are prone to syringomyelia?

Syringomyelia (SM) in dogs is a relatively common condition that mostly affects Griffon Bruxellois and Cavalier King Charles Spaniels, leading experts to believe it is an inherited disorder.

How to help a dog with syringomyelia?

What is the best treatment for syringomyelia?

Doctors usually recommend surgery for cases of symptomatic or progressive syringomyelia. There are two general forms of treatment: restoration of normal CSF flow around the spinal cord, and directly draining the syrinx. The type of treatment depends on what is causing the symptoms.

What medication is used for syringomyelia in dogs?

Medical therapy for syringomyelia may include management with steroids like prednisone or dexamethasone, pain medications like gabapentin, pre-gabalin, or tramadol, and medications to decrease fluid production like furosemide, omeprazole or cimetidine.

Syringomyelia symptoms usually develop slowly over time. If syringomyelia is caused by brain tissue pushing into the spinal canal, it is called a Chiari malformation. Symptoms generally begin between ages 25 and 40.

What happens if syringomyelia is left untreated?

If not treated surgically, syringomyelia often leads to progressive weakness in the arms and legs, loss of hand sensation, and chronic, severe pain. In most cases, the disorder is related to a congenital abnormality of the brain called a Chiari I malformation.

Medically, the "Rule of Three-To-Six" suggests waiting three times the typical seizure interval to confirm seizure freedom after an intervention, but potentially longer (up to six times) if seizure risk is high, while clinically, the 3 S's (Stay, Safe, Side) guide first aid: Stay with the person, ensure they are Safe, and turn them on their Side for breathing.
