Man, wish I could take a camping trip to your place! A few days, a twelve gauge, and my trusty 270 would have em cleaned up in no time! Yotes are mangy little critters, scavengers. They send a lot of time near bacterial infected kills as they eat what they can find. I wouldn't worry too much of rabies rather than a bacterial infection if he ever gets nipped. We've let dogs eat the carcasses after skinning hides and haven't had a problem but have found a lot of parasites on hides before, ie flea like critters. I'm sure there ought to be someone in your area who would love to take care of the yote problem
Howdy from Idaho!
