I stumbled upon this website and noticed Thunder Valley Dogs. Unbreakable Dobermans. I guess ANKA and PRIMA haven't retired and are still popping out litters.
What gives looks like they breed with Immortal Dobes too. :confused2

Here is another link regarding them. Immortal I think is on here - not sure she post much. Immortal is new to dobermans. You can probably research her kennel name and come up with info.
