Clinical signs can vary widely between dogs and there is no relation between the size of the syringomyelia and the severity of the signs; in other words a dog with severe fluid build-up can have relatively mild symptoms, and vice versa. The most common symptom that develops is intermittent neck pain, although back pain is also possible. Affected dogs may yelp and are often reluctant to jump and climb. They may feel sensations like ‘pins and needles’ (referred to as hyperaesthesia). Another common sign is scratching of the neck and shoulder region called ‘phantom scratching’, as there is generally no contact of the foot with the skin of the neck. Occasionally dogs become weak or wobbly if there is significant damage to nerves within the spinal cord. Cavalier King Charles Spaniels will typically show clinical signs between six months and three years of age. Not all dogs with syringomyelia will show signs of pain or other clinical symptoms, and so the presence of syringomyelia can be an incidental finding on an MRI scan. Other neurological conditions, such as slipped discs (cervical and thoracolumbar disc disease), can mimic the signs of syringomyelia and it is important for us to rule them out before concluding that your pet is suffering from syringomyelia.
