I don't know what the stats are for affected DM tests BUT in Labradors, with the EIC (Excercise Induced Collapsed) there is a percentage of affected dogs who will never have symptoms during their lifetime. We can only use our test results as a guideline. The whole picture must be considered. Barb Hively - PA DNA.

When we get a dog with DM tested markers from two arents who tested clear, what do we do? I have heard it is not possible, ut I remember that from clear hips in the past. also remember a friend of mine who when elbow x-rays came out, tested all her bitches. They all tested with bad elbows and she put them all down. ithin two years she was out of the breed. ssume just for the sake of discussion that Gotti, Ben and Mephisto had the markers for DM. Should all of the progeny be put down? I guess that is personal opinion and can't be answered. s the breeder and owner of Big Ben, I guess I can ask that question. I o not have the answer. A good friend of mine, Liz, said it is just a factor o use in breeding. I tend to think she is right. van Ginsburg sgard German Shepherds ttp://www.asgardgsd.com/ here Type Movement and Temperament come together ===========================================================================OST is Copyrighted 2011.
