Blackmouth cur question

I posted that picture of Lewis Woodruff at 21 with two leopard dogs. Breeding for color is a fairly recent trend in cur stock dogs. In the old days, when you had to have dogs to gather your stock out of the big woods, getting the job done was important and color didn't matter. Those men were of the opinion that if they got the job done where they used them, they were the right size, if they held up to hard use day after day, they were made right and color alone didn't help make a living. My dogs go back to Woodruff dogs that were black, black and tan. and yellow that were bred to some spotted dogs. They are heavy line bred and they all come yellow except for a blue tinted one now and then, which blue is a dilute of black. Pure dose not exist in cur stock dogs of any color and the Wright dogs go back to Woodruff dogs.
