One of my girls was bred to a brown before she was mine. What they got was ten black puppies who throw brown pigment. AWFUL!!!! The pups themselves were pretty enough blacks, but two of the females were held back for breeding and their pups, whether balck or red have awful pigment.
Brown and red are both recessive colours, so usually a breeding of these two colours will produce black, and not great blacks at that. This does not sound like a breeder who has a clue what they are doing. Bigrredpoodle is correct. THIS is what we are all trying to avoid and breeds away from. Terrible idea!!!
