Doberman's aren't Black and White?!?

Abby had puppies today! She was a week early so it caught us completely by surprise. We had taken today off to get the wash room ready for her and get her whelping crate ready. She whined to come in and was laying in her crate while I cleaned. I walked out of the room to get something, and when I came back in there was a cleaned off puppy in her crate! We were so surprised. We called my Oma to make sure we were doing everything right (she's whelped hundreds of puppies so she's pretty much as expert as they come). She told us everything we needed and told me to call her if we needed any more help and let her know how many we got. Well when all was said and done Abby had six puppies. We called Oma to tell her about them and she asked us what colors, Justen told her 4 black and 2 black and white. She got really upset and told him, "What is wrong with your puppies, Doberman's aren't black and white?!?" Apperently we never told her it was Abby not Tia having puppies.
So back to the puppies. We got 2 girls, marked similarly to abby white blaze on the face and part of a collar. 2 Girls that are black, one with grey paws the other with a white spot on her chest. Funny thing is we also got 2 boys with the same markings as the two mostly black girls. If I didn't know that they were Border Collies, I'd say we were raising black labs around here. Garrison is really a bit confused. He keeps pointing at Abby and saying "Abby, uh-oh, meow?" He seems pretty convinced that a litter of kittens has invaded his basement. We only let him have a peek today so Abby could rest, but he sure does want to get in there to Abby and the Meows. But he was pretty satisfied to have Tia's undivided attention today since she was also banished from the washroom for the day.
