Bantering and play are a big part of life for coyotes
Teasing and provoking by pulling on your friend’s leg or neck, ducking and evading, a swing to the left and another to the right, baring your teeth and lowering your head — all the while keeping your ears in a low, non-aggressive position. This is how coyotes play, and they usually do so at their *rendezvous*: after spending daylight hours sleeping and apart, they come together for their social activities around dusk time.
Afterwards, there is a grooming session, where they accept the grooming caresses from each other as they calm down.

This play can involve a mated pair, it can involve a parent and a pup as long as the pup shows proper obeisance, and it can involve adult siblings who actually live apart but continue their childhood relationship for a while.
