Actually twice this past deer season. I startled a couple of dogs walking to my tree stand one morning. they circled behind and followed me to my stand in the dark. A week prior to that i had 7-9 coyotes come out of the thicket right at dusk, and about 25 yards from my stand played host to a violent royal rumble. The dog fight went off and on for 5 minutes or so. I couldnt see much of what was happening but there was plenty of growling and snarling. After it ended the dogs split in all directions in the woods. It made for an loooooooong walk out of the woods.
