Unfortunately around 20 years or so ago it was discovered the Glen of Imaal Terrier suffers from an hereditary eye disease called Progressive Retinal Atrophy. The breed worldwide pulled together to combat this & the two research projects, Optigen in the United States and Bochum in Germany, arrived at the self same discovery within weeks of each other!
DEFINITION OF PRA
~ Progressive a slowly developing disease process ~ the affected dog will gradually lose its sight and will usually adjust to its handicap
Generalised progressive retinal atrophy (GPRA or PRA) was first recognised in the Glen of Imaal Terrier in the mid 1990’s. This condition causes gradual loss of vision. To develop PRA, an affected Glen has to have inherited two copies of the disease gene … one from each parent. Up until recently, the only way to diagnose PRA in the Glen was by eye testing. Glen PRA is late onset, with some affected Glens not showing any clinical signs of disease (by eye examination) until seven years old and older … in many cases after breeding duties were completed. This made it almost impossible to “breed out” PRA from the Glen gene pool.
In 2010, the gene that causes Glen PRA was identified. The Glen is the only breed
with this particular variant of PRA … cone-
Professor Bedford, a veterinary eye specialist and patron of the Glen of Imaal Terrier
Association (UK) writes on GOITA’s Glen Health page, “As a breed you have already
developed the discipline of eye examination and you should continue to be certain
that another problem does not become entrenched within the breed …… Eye examination
is essential to ensure that our delightful breed remains free from other potential
ocular [eye] disease.”
There is no consensus as to how often eye testing should be done, but at 2-
For information about how you can arrange to have your Glen eye tested or DNA tested, please click here
Eye test results can be found for individual Glens on the Kennel Club website.(DNA results for CRD 3 are also listed. The EFG organise an annual eye testing session in July. Other sessions are held around the country by breed clubs and canine societies. Please use the Contact page to enquire about DNA and Eye Testing Sessions
NB. Your Glen must be either tattooed or microchipped for both DNA and eye testing
Details can be found on page 11 of the DNA booklet

Want the full Glen of Imaal Terrier/ DNA and breeding story?
The document cover on the left will take you to the DNA/Glen of Imaal Terrier story (full digital copy) in a lot more depth & it is suggested you do it if you are thinking of mating your Glen either now or in the future. If you are thinking of breeding AT ALL you owe it to Glendom (and the owners of any of your puppies) to make sure your dog or bitch has been DNA tested
