Why Do Dogs Roll In Weird Shit?

One study traced the behavior to hyenas. Researchers sprayed hyenas with two scents, carrion or camphor, to try to understand the behavior:

Donning eau de carrion led to heightened and positive social interactions … regardless of the social status of the odor-wearer. Termination of the ceremony also ended peacefully with the carrion odor, unlike some of the other greetings, which met with aggression. It's probably wise to be on friendly terms with the guy who can lead you to the meat. …  Drea and her co-authors conclude, "rolling may ultimately promote social cohesion."
