HuffPost Live on Friday hosted a discussion about how some dogs seem to show bias against people with darker skin, an idea explored in popular culture for years, including in the 1982 movie "White Dog," and more recently, in an episode of "Curb You Enthusiasm" and a "Key and Peele" sketch.

Writing for Newsweek in 2010, columnist Raina Kelly said that dogs simply lack the cognitive capacity to be racist. Racist Dogs: Why Do Some Dogs Seem Not To Like Dark Skinned People?
