Hello,

Bad news about DM ...
A french breeder of TWH was very surprised as she received the results of the DM test for some puppies from litters born by her :
- Rambo C.W (DM/DM) x Chaddey Spod Dumbiera (N/N) produced a male which is N/N
- Rambo CW (DM/DM) x Bubka de New Flame produced a female which is N/N
- Sibir C.W.(DM/DM) x Bubka de New Flame produced a female which is N/N too

Filiation test were done, it's proved that the parents are the real parents.
Rambo has been tested twice, the 2 times the result was the same : DM/DM, it's the same for the descendants.

A problem was noticed by another breeder : a couple from free TWH produced a female which is carrier (DM/N).
Genetical test were donne too, to prouve that the parents are the real parents, and they are.


What do you think about it? mutation? transmission not only based on a autosomal recessive mode? (that was previously already supposed)
I think we can transpose it to the SWH ... and also we cannot deduce that from 2 parents which are free from DM all the litter will be free too ... maybe in the major part of the cases, but not at 100%
Do you have more infos about the transmission of the DM?

Additional researches are going to be done at the university of Prague:
