Anyway it does not matter where it comes from, what they need to invent a test for CSW is blood of a dwarf to find out if it is the same gene as in GSH and SWH and if the same test can be used or if they need to invent a second one. When there is a test you can find out where it occures in the lines.
It may come from crossing with Saarloos because of the different GSHs used in this breed but this doesn´t matter at all in the moment and only matters to find gene-carriers in the future. Not all GSH are automatically carriers.
Maybe it would be another possibility to get samples to test died puppies.
The HD-Test showed that there are a lot of carriers even in breeds that don´t have any HD-problems in their population, like Mallinois and Sight-dogs. This makes me a little bit sceptical how to use it at this point. New Tests on complex deseases like HD (that is not compareable with dwarfism in this point) allways include the danger of mistakes in the beginning and should be carefully used on populations with small gene-pools because they may wrongly decrease the pool. It seems to me that there has to be more research done how to do the management in breeding with this test.
