What it is
Clear fluid flows around the brain and spinal cord, cushioning them and carrying waste away. When the back of the skull is too small for the brain inside it, or the opening at the base of the skull is crowded, that flow is disturbed. Pressure changes push fluid into the spinal cord itself, and pockets of fluid form there, pressing on the nerves that carry the sense of touch and pain.
The condition is linked to the shape of the skull and is inherited, and small dogs with a short, domed head are at greater risk. Signs may appear in a young dog or later in life.
A dog with syringomyelia can find things uncomfortable that other dogs never notice: a collar pressing on the neck, a bowl on the floor. A harness instead of a collar, a raised bowl and a quiet place to rest help it feel more at ease.
Signs you may notice
- Scratches at the air near the neck
- Dislikes having the neck touched
- Yelps for no clear reason
- Reluctant to lower the head
- Weak or clumsy movement
You may notice the dog scratching at the air without touching the skin, especially around the neck or shoulder, disliking having the neck touched, yelping for no clear reason or being reluctant to lower the head. Weakness or uncoordinated movement may follow later.
When to see a vet
Book a visit if your dog scratches at the air, yelps for no clear reason or avoids having its neck touched.
