The bottom line

Dogs yawn when petted because stress and sleep both open the mouth — pair yawns with lip licks and turned heads before assuming they're bored. Shorten petting, change body zone, or end training when yawns stack. Medical causes are uncommon but worth checking if yawns come with drool, pain, or appetite loss.
