Doberman colour is controlled primarily by two gene locations: black vs red and dilution. In this litter, the dam is genotype #7 (red) and the sire is genotype #3 (black carrying red). Because red is a recessive trait, a puppy must inherit the red gene from both parents to be red. That pairing can produce a mix of red and black puppies. The red girls inherited a red gene from both parents, while their black littermates inherited only one red gene and therefore express black (

At nine days old, Doberman puppies are still in the neonatal stage of development. During this time, they spend nearly all of their day sleeping and nursing, with growth happening rapidly but quietly. The puppies in this litter are not yet able to see or hear. Their eyes and ears remain closed, and movement is limited to instinctive crawling and rooting behaviors that help them find warmth and nurse efficiently. At this stage, a calm environment and consistent care are essent
