DNA screening for breeds H - O

The Kennel Club, in conjunction with a number of other organisations and the breed clubs concerned, runs DNA screening schemes for the following breeds for the diseases specified below. For further information on the specific conditions, and lists of results, click on the links.

The DNA tests used in these schemes can accurately identify clear, carrier and affected dogs, and can be used by breeders to effectively eliminate undesirable disease genes in their stock. It is anticipated that additional schemes will be available for other inherited conditions in other pedigree dog breeds from time to time.
