Not sure about regs and rules where most of you guys hunt as far as protecting yourselves against wolves and bear. If you're in a situation where you may be confronted by wolves or bear while packing meat and can't shoot them due to strict regs consider a dry chemical fire extinguisher and possibly a can of hornet spray, the foaming 30 footer type. I was on a raid time once upon a time and I know a blast from a dry chemical extinguisher will knock the wind out of large pit bulls and rotties in no time flat. The dry chemical will suck the O2 out of any animal instantly when hit in the face. A little heavy perhaps but it works.
