The President of the Czech Weimaraner Club has sent the WCGB the following information.

In 2018, a few Weimaraner dogs in the Czech Republic were diagnosed with DCM (Dilated cardiomyopathy). With regard to the life-threatening dangers of this disease, the Weimaraner Club of CZ decided to make DCM tests (echocardio tests) mandatory from November 2018.

Already 136 dogs have been tested, of which 10 are positive for DCM. In addition, information has been received about DCM diagnosis in 9 other dogs.

Based on the echocardio test results, the Club takes the following steps:

  1. Excludes the breeding permission of the affected dogs
  2. Suspends the current and possible future breeding permission of the relatives of the affected dogs (siblings or the first generation progeny)
  3. Implements a compulsory cardiological and genetic screening for all the breeding individuals

Currently, there is no DNA test for a Weimaraner that would help with diagnosing and preventing DCM. The Club has started genetic research in pursuit of developing such a DNA test. The Czech Club has received Information from other clubs which solved a similar problem years ago. It would appreciate any information which would help reduce the risk of DCM and recommends that all Weimaraner breeders take the echocardio tests with all of their dogs.

If you have any questions regarding the Czech Club’s experience with DCM or questions regarding breeding individuals, please contact their breeding consultant

What is dilated cardiomyopathy?

DCM is a heart disease in which the heart muscle is weakened and is unable to pump effectively. As the disease progresses, the chambers of the heart beome enlarged and the valves may leak. The heart becomes increasingly weaker and less able to pump blood effectively and signs of congestive heart failure develop. In the early stages there are few symptoms, sometimes the dog develops signs of exercise intolerance. The vet may detect a heart murmur or other abnormal sounds. In time, the pumping action of the heart gets weaker and fluid accumulates in various parts of the body. The dog is weak, pants excessively, coughs and is prone to fainting and the symptoms get worse with time. The disease can be detected by an electrocardiogram (ECG), the technique used to screen breeding dogs.
