The Kennel Club officially recognises three conditions that affect Collies (and several other breeds) – CEA (Collie Eye Anomaly), PRA (Progressive Retinal Atrophy) and hip dysplasia. Screening has been greatly enhanced by the introduction of DNA testing over the last few years and two further conditions are being monitored in the breed, MDR1 (multi drug resistance) and DM (Degenerative Myelopathy).
None of these conditions are exclusive to Smooth Collies but the Club is encouraging breeders to screen and hopefully gradually eliminate where possible whilst ensuring that diversity is maintained to prevent other conditions being introduced.
The KC Assured Breeder Scheme requires all breeding dogs to have annual eye screening and recommends that they are hip scored and DNA tested for CEA and MDR1. It is also recommended that all puppies are eye screened by an approved canine ophthalmologist at between 5-12 weeks of age .
