Hello Mijke,
I'm willing to donate DNA-samples of my dogs... But I only have 2 wolfdogs, so I guess that's not enough to start a DNA-database

But I'm sure that a lot of people will try to help, if there comes such a research or such a database... So maybe you can ask that genetic specialist if he's really interested to set up such projects. I think that many wolfdog-owners and breeders will help!
You told that your own dogs are DNA-tested... What includes such a test? Did they set up their whole genome-chart, or is it just a kind of marker-test for genetic diseases?
Very interesting...
Greetings,
Liesbeth
