Most pedigree breeds of dog have some health problems that can be carried through the generations and the Glen of Imaal Terrier is no exception. This page introduces two hereditary disorders, Progressive Retinal Atrophy and Aortic Stenosis. Progressive retinal atrophy (PRA) is well-documented in this breed and, in 2010, Cornell University in the USA and Bochum University in Germany, announced that a single gene mutation for Glen PRA had been identified and testing for the ADAM9 mutation was available. Aortic stenosis (AS) was first diagnosed in a Glen of Imaal Terrier in 2002 and a breed survey to look at the incidence of heart murmurs was undertaken.Please scroll down the page for a brief „overview” of these health issues and links to further information.
Progressive retinal atrophy (PRA) is an inherited eye disease, now known to affect some Glen of Imaal Terriers. Affected Glens will eventually lose their sight. With the availability of DNA testing for the crd3 variant of GPRA that affects the Glen, breeders can avoid breeding combinations that have the potential to produce puppies that are at risk of developing Glen PRA, and the disease can be eliminated from the gene pool within a few generations.

Specific breed information about PRA and DNA testing.
Aortic stenosis (AS) is a defect of the aortic valve, which causes a partial obstruction of blood flow from the heart. This hereditary defect may be mild and not affect the quality or longevity of the dog’s life, or it may be severe and result in symptoms of exercise intolerance and syncope (fainting). It is also one of the causes of sudden death.
