The Canine Genetics team at the Animal Health Trust (AHT) have launched several projects to identify the genetic variants that contribute to Hereditary Cataract (HC) in several breeds and are looking for Labradors to take part in their latest study.

The team, that work in the Kennel Club Genetics Centre at the AHT, hope the information will be used to help breeders lower the incidences of HC in their breed. So far they have carried out an initial study on Golden Retrievers, American Cocker Spaniels, Large Musterlanders and German Pinschers but further research is needed to investigate the genetics underlying HC. For this, they’ll need to collect data from at least 48 dogs affected by HC and 48 older dogs that are clear of cataracts in each breed.

The AHT will be holding a Labrador Retriever Health Day on Friday 21 October, open to anyone who has a Labrador over the age of eight. They’ll receive a free examination for hereditary cataracts, and donate a DNA sample to help with this research. There will also be a series of talks about other health problems that affect the breed.
