I'd have to agree with the buyer. I've been around them most of my life, and have seen many variations of color from light gray to tan, to red and brown. I even seen a white one (almost) while hunting in north East New Mexico. In Georgia, several years, I seen several mixed dog/yota running in a National Forest North of Macon, some of them were even spotted. I was told by a game warren that hunters had imported to yota to replace the declining fox population. They had crossed with wild dogs. The mixture made quite a vicious and cunning animal that would attack a man. Due to some of the dog breeds in the cross, they were rather large animals.
