Around here the issue is primarily wolves, once it gets into hunting season bears are mostly settling down for winter, but the wolves of course aren't. We used to wait 45 minutes to an hour before going out to track a deer to make sure it bled out before running up on it. If you don't they sometimes will jump up and keep running and clot or just die somewhere you can't find them. Now 30 minutes tops, any longer and there won't be anything left but a big wide circle of blood and bits and not much else by the time you get there. Sometimes happens even with the short time, and sometimes they jump and you've got more tracking or trouble with tracking because of it.
At the end of the day I'm really tired of the wolves, they have killed so much of our deer population combined with the hard winters we've had that there really aren't many deer around. Right now I've got 4 coming in, a big doe, last years fawn, and twins from this year. I'm not shooting any of those 4, mostly the doe is the only one who would be worth taking, and well maybe I'm a softy since they have been hanging around the house for several years. But that said I haven't seen much of anything else at all this year at my house.
