Coyotes are very common around here, i see them daily and hear their chorus almost every night and morning.
A single coyote almost never poses a treath but for small children and little animals.
Some times in winter they run in a pack,that's when they can get dangerous and will take on any dog or other animal,or man for that matter.
I had a big lab killed by them a couple years ago out in the field under my very eyes.
The snow was to deep to get to the resque.
I usually carry a rifle in the tractor,but not that day
One also killed my Wife's little doggy a couple years ago.
