I was Sirbma's first-born pup. Sierra was a potential name for me. If the litter had been S pups. I was again the only differently-coloured (black and white) pup in a litter of black dogs – just like Oreo! Maybe we are destined to produce a litter of black and white super-dogs when we are older. I’m the most independent of my siblings and the others always follow my lead.
