Racist dogs?

So, I had a package delivered today from a ups male who was black. When he got out the truck he was literally looking around like someone's about to kill him, so i asked if he was okay. He said, yes but he noticed that dogs who belong to white people seem to be racist compared to dogs belonging to black. I assured him my dogs wasn't racist, and they're always up when we expect deliveries because typically they free roam my yard. After that we had a couple minute conversation and he went on his way.

This really has me thinking, do you believe dogs can be racists? Or maybe they pick up on their owners racism? 🤔
