Here's an image of my winning White Powder dog. His dam is a littermate to an American Field Pheasant Futuriity champion.
When I purchased him the breeder told me that his sire was National Champion Miller's True Spirit and had the breeder's certificate in hand. Another field trialing friend that worked with Ferrell and his dogs, and is now one of that strain's top breeders questioned my dog's lineage after watching the dog compete. He thought the dog had more of White Powder's attributes than True Spirit. DNA proved him right. I'm pleased with knowing the true sire was WP.
Big is one of the the smartest animals I've fooled with in close to six decades of fooling with pointers, he's sometimes a bit too smart for this old fart.
