As we do not know the other factors that cause the clinical onset of DM, we cannot predict what percentage of dogs testing “At-Risk” (homozygous for the susceptibility gene) will develop the disease. Dr. Coates’ research of the Veterinary Medical Database (VMDB) showed that 13 of 1,567 (0.83%) Chesapeake Bay Retrievers presenting to veterinary teaching hospitals had clinical DM. Presently, 15% of Chesapeake Bay Retrievers test “At-Risk” for DM. It is obvious that the vast majority of “At-Risk” dogs will not develop DM."

I think it is exactly what we can observe by our breed... Only small percentage gets ill.
What would be also interesting is the age when the 0.83% get ill...

I'm not for ignoring the DM problem - because it is really important to make bigger reseach and to test as much dogs as possible... But the whole "DM panic" started by some breeders is really without sense.

Because now we miss one VERY important thing... There are lines by CzWs which have SERIOUS problems to move properly already at the age of 2-4 YEARS... And some dogs from these lines have been tested with N/N. So for 100% they do not have DM... They are also HD-free...
So there must be also some kind of much more "dangerous" "illness" that DM...

At the moment some breeders went crazy for DM tests and there are already some which decided not to use DM-carriers but took "DM clear" dogs from... the "bad walking" lines.
So for sure their puppies will not have DM problems at the age of 10, 11, 12... 15 years. But it is very possible they get problems already at the age of 2 years.... (because of the hip problems which are not diagnosed now)...
