Quick lesson on pitbull bloodlines and color. A red nose dog only is a description of its color and nose. It is not a blood line. Bloodlines generally establish the high price of a dog. Generally because the dogs in a bloodline have been shown,fought or competed in weight pulls and come with a high pedigree registered with AKC, UKC and ADBA. The quality and price of dogs follow that order, akc most valuable and reputable, UKC 2nd, adba 3rd. As far as color alone making a dog valuable, the most valuable and rare color is yellow. Both mom and dad have to carry the yellow gene BUT that doesnt mean the 2 dogs will ever have a yellow pup. I live the red colored dogs, I once seen a red on red brindle that was amazingly beautiful, but color of nose and coat generally dont add value alone. A quality looking pit like u have is worth between 200-500$ generally so u made a good purchase and have a fine dog there.
