Like, when you pet a dog/cat, their skin is sort of looser, they have a scruff of the neck and lots of rolls. But in humans, the skin is tight on the meat, even on the hairy parts like the scalp. Is there a reason for this?
In: Biology
Most dogs have loose skin. dogs bred to keep wolves away from livestock tend to have even loser skin than most dogs. Most mastiffs if you grab them by the scruff of their neck, can turn their heads fully around and bite you, which is not an accident of genetics.
