Ive watched a male dog follow a male female pair of yotes last year. You could tell the fm yote was in heat. The m yote would turn and fight and the fm would keep moving on at a walk trot. The dog was a big blk lab mix the neighbors dog tough farm dog. This went on for a good while I watched with binoculars from the road.The males fought hard 3 or 4 times as they followed the fm. They went over a hill and I never saw them again. I do know the dog is still alive
