How common is this deficiency in the Kerry Blue Terrier breed?
The frequency of Factor XI deficiency remains unknown. While in the past there have been difficulties to get dogs screened for this deficiency, the new DNA test has not yet been embraced by the KBT owners and breeders. Few dogs have been screened and some were screened because relatives were diagnosed with the bleeding disorder. It would be helpful to the breed to screen a random group of champion and breeding KBTs to further determine the prevalence.
