its all about genetics n genes. breeder have coloured pups in some litters they have bred the white gene is usually prodominatley the stronger gene. but i do have a black n tan n a red out of whites, dont be led astray by the russels ther not. look at the heads. thats how his mum was breed, also his brothers and sisters were black n tan, another simmilar example of the same thing happening is that 1 of the patterdales are white and brown, cheers.
