Should they be used?

Everybody in Glen of Imaal Terriers should be aware that they have PRA and that a DNA test has been developed but what to do with the results? What do you do if your beloved animal is found to be a carrier, should it be removed from the gene pool totally or, if good enough, bred from? It can be a difficult decision that might need some thought and advice from others.

  1. According to the Swedish Kennel Club rules, we are allowed to use the carriers, so long as they are bred to clear dogs. It increases our security and breeding stock. It also opens the possibility to use dogs and lines that we thought were useless! And it opens up many new opportunities!

  2. Of course a carrier is acceptable to breed from if worth breeding from. Breeding only from clears will narrow the gene pool even further and bring far worse defects up to the surface.

  3. Well said Marie appication of commonsense as long as people breed carrier to clear .

  5. with ref to the carriers. to quote prof bedfords comment ‘you can’t throw the baby out with the bath water’. at the moment we do not have enough clear animals but as long as clear goes to carrier all should be ok. eventually weeding out the clears we should in a few generations have enough clears not to have to use carriers.

  6. The only way in telling the exact state of a dogs hearing is to BAER test (brainstem auditory evoked response). This method can distinguish between a totally deaf dog, a dog that is unilaterally deaf or a dog that can hear normally.

  7. WHAT IS IT?Mitral dysplasia is caused by faulty heart valves.When the valves do not work as they should some of the blood goes into the atrium when the ventricle contracts instead of leaving the heart, leaving the body with less blood.The heart tries to compensate by working harder and increasing the function. As this happens the valves get worse and the body gets less blood. As a result the heart can get enlarged from being overworked.The end result being the animal dies.This condition (commonly picked up as a heart murmur) can very from mild to severe.You may never notice if your dog has a mild case, however should these dogs be bred from their offspring have a good chance of being effected and are often more severely effected.How common is it?Veterinary cardiologists recently held a screening session at some of the Bull Terrier club shows.Their findings were that between 25 to 40% of Bull Terriers have heart murmurs.It is not unusual for young puppies to have mild heart murmurs that they normally grow out of.DETECTION AND PREVENTIONBreeding animals should be tested by a vet with a certificate in cardiology and can be detected on auscultation (listening to the sounds made by the heart using a special stethoscope) or performing a Doppler ultrasound scan if the results are unclear.The results are given either as clear or a murmur graded from 1 – 6, six being the most severe.A uaual vet can normally only detect murmurs from grade 2 – 3 upwards and as the mode of inheritance is still unknown animals with murmurs should not be bred from.You can help stop this problem in the breed by having your animals tested before breeding from them.
