Why do dogs spin before lying down? The surprising reason has nothing to do with comfort but ancient survival instincts

Dogs spin in circles before lying down for a reason, not by accident.

The instinct survived domestication and still appears in millions of pet dogs today. The American Kennel Club says this pre-sleep routine is usually normal.
