Not last year but the year before in late September I had yotes come in on my dogs two mornings in a row at the same spot, it was dark yet, luckily they did not come in silent. I went straight toward the yipping and barking yotes, the first morning they were in a soybean field on a hill side, when I got my headlamp on them it was 5 sets of eyes. They quickly left. Next morning they came in from a thick bottom, again once they knew I was getting near them they got quiet and left, I did not see them this time. If this had been spring or early summer when they had small pups and I was in their territory I am sure they may have attacked. I ran this area all summer and had no problem , so they probably were not territorial, maybe curious. If they wanted to attack they easily could have. Maybe if I did not let them know I was there they would have attacked. If they had a pattern of coming to my dogs I would have set up, to see if I could have got a shot.
