With the intention to breed as responsibly as possible, we decided a few weeks ago to have Merry genetically and clinically tested. You have already been able to read the results of the DNA test for MAC and the clinical ECVO eye tests, but now also the results from two other DNA tests has reached us. We are therefore very happy to inform you that Merry is not a carrier of the gene that causes PRA-B, nor of that associated with Congenital Myotonia.
PRA B? Progressive retinal aortas (PRA’s) are a large group of inherited diseases that are a major cause of blindness in multiple breeds of dogs. And although the B variant is not the only form that affects schnauzers, it is a very important risk factor. In recent years it has become known that there are more and more miniature schnauzers carrying a gene that causes PRA-B.

Myotonia Congenita? Myotonia Congenita is a hereditary muscle disease that can occur in miniature schnauzers. The disease is caused by a gene mutation that influences the function of the chloride channels, or the amount of chloride is reduced.
