After waiting several months, I finally can let you know that Nelly is also registered in the ASCA registry now. As a part of the registration we also had her DNA tested.
With this finished I could directly register the litter from summer 2018 and hope that I can soon tell you that also the puppies are ASCA registered.

As Rush is both registered in the ASCA and FCI registry (as Nelly is now 🙂 ), the puppies from the litter planned for winter 2020/2021 will get both ASCA and FCI pedigrees!
