Prevalence of asymptomatic syringomyelia in Cavalier King Charles spaniels
The prevalence of syringomyelia was investigated in a sample population of 555 Cavalier King Charles spaniels. All dogs, which were declared by their owners to be showing no clinical signs of syringomyelia, underwent MRI to determine the presence or absence of the condition. Data were analysed by logistic regression to determine the effects of sex and age on the prevalence of syringomyelia. Only increased age was found to have a significant effect. The prevalence of syringomyelia was 25 per cent in dogs aged 12 months, increasing to a peak of 70 per cent in dogs aged 72 months or more.
This is a recent study of 555 cavaliers without symptoms, many of them being screened before breeding.
One in four had a syrinx at one year of age.
Nearly three out of four had SM by the time they were six years of age.
Thank you for doing this. Breeders need to be aware of the true facts.
