Hair of the dog

Discovery News reports:

The color of a dog's fur may seem to be just a whim of nature and genetics that reveals little about the dog. But a new study claims that coat color for at least one breed, the English cocker spaniel, reflects a pooch's personality.

[This] study, recently published in Applied Animal Behavior Science, determined that golden/red English cocker spaniels exhibit the most dominant and aggressive behavior. Black dogs in this breed were found to be the second most aggressive, while particolor (white with patches of color) were discovered to be more mild-mannered.

In labrador retrievers, the color rank from most to least aggressive was determined to be yellow, black and chocolate.

Update: Dustbury has a great critique of this study, especially the stuff about dachshunds.
