Day of the dead
I don't think it's to disguise the scent. Wolves will go for the easy meal.
I think when deer smell wolves and carrion from the same direction, they think the wolves are scavenging and not hunting, so they become less alert.
I never really gave much thought to the benefits of rolling in dead animals.
It's a neglected area of study. I expect it will become more prestigious when Bowman's wolf researchers get into the field.
