Reading the breed notes in the Our Dogs paper, I noticed that the two main Chihuahua breed clubs are organising a health seminar at which Dr Holgar Volk from the Royal Veterinary College is going to speak on epilepsy and - syringomyelia. I find it interesting that they feel there are enough breeders and show people interested (if not yet directly concerned) in SM in Chihuahuas to warrant putting on a seminar. I believe that hydrocephalous (fluid in the brain) is fairly common in Chihuahuas, and as the symptoms of this are very similar to the symptoms of dilated ventricles in Cavaliers, it may be that CM and/or CM/SM occurs more often in the breed than breeders realise.
