The RVC says that until now, there has been little reliable evidence on the frequency and severity of syringomyelia in the overall dog population, which has limited veterinary surgeons’ ability to diagnose and manage the condition.

It's not just syringomyelia for which there is a lack of data. Scientists have for years struggled to identify the true extent and severity of diseases seen in the wider general dog population because the main source of veterinary health data on dogs has come from universities and referral hospitals.

While this referral data is useful, the types of animals and conditions that are referred to these referral centres is unrepresentative of the wider dog population, making it very difficult to extrapolate any findings to the general population. The vast majority of animals are managed perfectly well by the primary vet practitioners without ever being referred or even being ill at any one time. 

However, through VetCompass, the RVC is now collecting anonymised clinical data from first opinion veterinary clinics across the UK; data which is being analysed to answer a wide variety of previously unanswerable health questions. 

The VetCompass syringomyelia study published in the Veterinary Record is a case in point. It highlights for the first time the frequency and severity of syringomyelia seen in general practice in the UK.

At an overall dog population level, syringomyelia is not that common, affecting just one in 2,000 dogs. But among Cavaliers, the frequency of syringomyelia is much higher, affecting one in every 60 of the breed. VetCompass data reveals that almost 2,000 Cavaliers suffer from clinical syringomyelia in the UK at any one time. 

Syringomyelia is a severe condition for affected dogs, with the VetCompass study showing that 72% of affected dogs were recorded as showing pain. The study showed that these dogs would often yelp or scream when they were picked up or when their necks were touched. Many of them also showed ‘phantom scratching’ where they would try to scratch at their necks with their hindlegs but without ever even making contact with the skin. Some people refer to this action as ‘playing an air guitar’.  

The RVC is urging veterinary surgeons and owners alike to be aware of the symptoms of syringomyelia, so that clinically affected dogs can be recognised and treated earlier and better. Symptoms include:

  • Sensitivity around the head and neck area
  • Sleeping with the head raised
  • Scratching or pawing the head or neck region
  • Weak limbs
  • Deafness

Dr Dan O’Neill, Companion Animal Epidemiologist at the RVC, said: "I loved being a first opinion practice vet for over 20 years where I could help animals on a one-by-one basis. But now, with VetCompass, we can help animals by their thousands. An example is this syringomyelia study which may lead to many affected dogs getting treatment much earlier and therefore making their lives so much better."

Professor Holger Volk, Professor of Veterinary Neurology and Neurosurgery, said: “These VetCompass data are an eye-opener; we very frequently see Cavaliers with clinical signs of syringomyelia at RVC’s referral hospital but now we know how common it is in the real world, outside of the referral world."

Dr Ludovic Pelligand, Senior Lecturer in Clinical Pharmacology and Anaesthesia, said: “VetCompass allows us to identify how Cavalier King Charles affected by syringomyelia are treated for pain every day, nationwide. This will help us to understand optimal management and we are currently working on new ways to monitor pain and working towards developing new treatment options to further improve their pain relief and quality of life in the future".
