when the caucasian lived in the caves and hillsides of Europe of the Caucasus Mountain range... THEY lived the life of a beast... walking on all fours... eating raw meat... killing their newborn... sleeping in their defecation.
THEY befriended the wild dog and made them part of THEIR family... even today THEY call the dog THEIR "best friend".
THEY would use the dog to help them hunt and track and to also act as a lookout and guard the women and children when the men went on THEIR hunting trips.
Sometimes these hunting trips would last days and weeks... leaving the white woman at "home" at the cave.
With the white woman being a natural freak... she started lovemaking with the dog.
After 2000 years of this... the dogs sperm entwined with the flesh of the human... and now whenever white people get wet or sweat the odor of dog appears...
