My dads dog was used to being walked in Wiltshire, with a very white local populus.
When I first started walking Harry on the Thames path down in Kew he would get very agitated by people who were not white. He would start barking and cower. Took about 6 months visits to leafy Kew before he calmed down.
On a dog related note, my dog as a child was so fucking gay. He would only try to mount other dogs, no interest in the bitches.
they say dogs are like their owners...
