Interesting study: Dogs raise their left eyebrow (left facial lateralization) when reuniting with the person they are attached to. Very cool! From a summary by Ken Pope, PhD: "Dogs show left facial lateralization upon reunion with their owners." by Miho Nagasawa, Emi Kawai, Kazutaka Mogi, Takefumi Kikusui, of the Department of Animal Science and Biotechnology, Azabu University, Kanagawa-ken, Japan. In the study in which dogs from a dozen breeds participated, one of the findings was that when dogs see a person for just a glance (800 milliseconds), they raise their eyebrows a bit. If the person is someone for whom they feel love and affection (i.e., a beloved owner), the left eyebrow rises higher than the right; however, if the person is a stranger, both ears rise the same amount while the left ear moves back a bit in apprehension. A glance of a favorite toy elicits no response, but a quick glance at dreaded nail clippers caused their right ears to twitch."
