Puppy Eyes

This page provides information about DNA testing for crd3 and screening for eye disease (eye testing)

Progressive retinal atrophy (PRA) - a disease that causes dogs to gradually lose their eyesight - was recognised in Glens in the mid 1990s
It wasn't until 2010 that the gene mutation responsible for the Glen variant of PRA - called crd3 - was identified and a DNA test developed

DNA test for crd3

  • Breeders should ensure that they are not breeding puppies that are at risk of developing crd3

  • At least one of a breeding pair must DNA tested Clear for crd3 or be Hereditary Clear (where both parents are known to be Clear)

  • Clear x Clear (safe) mating
    All puppies will be Hereditary Clear and do not need to be DNA tested

  • Clear x Carrier (safe) mating
    Puppies will be either Clear or Carrier status
    These Glens are not at risk of developing crd3 but must be DNA tested if they are to be bred from

  • Clear x Affected (safe) mating
    All puppies will be Carrier status
    These Glens should only be mated to a Clear individual

Eye testing

  • There are several variants of PRA, as well as other types of inherited eye disease, and some breeds are known to have more than one form of inherited eye disease
    There are isolated reports of Glens with other forms of inherited eye disease and it would seem sensible to coninue screening the breed for ocular (eye) disease

  • Both parents to have an up-to-date eye test certificate at time of mating i.e. within the twelve months prior to mating
    Breeding stock to have regular eye tests throughout their lives - the recommendation is every two years until the age of 10 years

DNA TESTING FOR CRD3

DNA testing for crd3 involves a blood sample being taken from the dog by a veterinary surgeon. Blood is usually taken from either a foreleg or the neck, and the blood sample is then sent to one of the two laboratories offering DNA testing for crd3.

BOCHUM, GERMANY

Please contact EFG Secretary Mrs Jean Rogers for information about this service:

Tel: 01205 820791      Email: Jean@e-f-g.co.uk

The cost for the crd3 test at Bochum is €70.00 + blood draw and and shipping costs

OPTIGEN, USA

Mrs Val Tiller (Foxbarton Border Collies) organises two "all breeds" Optigen 20/20 DNA testing sessions per year, in February and September
This is a "postal participation" service, where you send your Glen's blood sample (taken by your own veterinary surgeon) to Val, to be sent to Optigen with her consignment of samples

Please contact Val in January (for the February session) and August (for the September session) for information and discount code:

Tel: 01372 273597      Email: val.tiller@talk21.com

Other Optigen 20/20 sessions

The Optigen Clinic Schedule lists UK sessions further down the page, under "Non-U.S. Locations"

NB Some DNA testing sessions only take cheek swabs, rather than blood samples
Optigen (and Bochum) will now only accept blood samples for testing for crd3, so please check that the session you choose has provision for taking blood samples

The cost for the crd3 test at Optigen is $100.00 + blood draw and shipping costs - Val can offer a 25% discount plus an extra 5% discount for online submission

Clear, Carrier and Affected results can be found on the Kennel Club's Glen of Imaal Terrier DNA screening page


EYE TESTING

Eye testing under the KC/BVA Eye Scheme has to be done by a Certified Veterinary Ophthalmologist. The examination involves putting some drops into each eye to dilate the pupil, and then the dog is examined in a darkened room.

The EFG organises an annual fundraising event every July, and Veterinary Ophthalmologist Professor Peter Bedford attends to conduct an "all breeds" eye testing session

Please contact EFG Secretary Mrs Jean Rogers for information:

Tel: 01205 820791      Email: Jean@e-f-g.co.uk

Follow the EFG Blog from around June-time

Venue: Hedge Green Cottage, Blackjack Road, Swineshead, Boston, Lincs PE20 3HH

Costs for eye testing can be found on the Brisith Veterinary Association website - group sessions attract a discounted rate

Unaffected or Affected results for individual dogs can be found via the Kennel Club's Health Test Results Finder
