Wolf Hybrid Question

There is no accurate DNA test to tell if a dog is part wolf or how much wolf. Since real red wolves are VERY rare and the ones in captivity are part of the government breeding program in qualified zoos and wildlife parks, it is VERY unlikely any mixbreed dog or wolfdog is really part red wolf. I see that claimed somewhat often and know it's bogus. The coloration on your dog is due to the sable gene (giving the reddish shading over other colors including white) which exists in many breeds and mixes of breeds of dog. It is not at all indicative of wolf heritage.
