I agree with this. My dog, the biggest hound-German shepherd mix cuddle bug on the planet, was a rescue when I lived in South Carolina. He was found wandering Hilton Head Island after the hurricane. (Literally hundreds of pets were abandoned during the storm, and many of them escaped homes looking for food since access was closed off for over a week.) Being jobless, I drove from Texas to help out for several months and worked for the Town. Unfortunately, my dog was a racist fuck for months. I finally have got him to respect everyone equally. The point is, dogs are extremely sensitive to how we treat others and mimic that ability. My dog's previous owner was likely a racist ass, which isn't that surprising in South Carolina.
