i have jst ordered a black lab bitch from good working lines, the breeders are the secretary to basc and writer in shooting gazette, they are both crufts judges. On colour they use black and yellow, they dont like chocolate and advised me that in their time as judges they have only seen 3 chocolate winners.They say they are harder to train.
Aside from colour i think that hip score is important, the parents to our one had scores of 5 each, both also eye tested ok.
