You better kill it first time you see it again, then you have the rest to contend with (there could be many) for a while. Look at my pics, theres nothing I hate more than a yote. As for your little dog, I would treat him the same as a free range flock after you know a predator is around. Dont let him out unless your out with him. Yotes are very smart critters, once you know thier around they will always bee around until they deplete the food scource. I recomend keeping some sort of firearm you are proficiant using close by, if you hear the flock alarming quietly slip out of the house and do what you need to. The ones I encounter around my neck of the woods have recogized the sound of the front door and even the sound of a safety on a firearm being taken off.
