I started carrying a leatherman tool specifically to pull porky quills from my dog(s). Ive had two dogs quilled, one was bad enough I had to make a vet trip from camp out in the mountains on a sunday.
I keep the training collar on the dog in the mountains, she doesnt really need it for the most part, but its to encourage instant obedience to ignore and come back when encountering a porky, moose, bear or whatever. Its also nice to use the beeper to call her in and not be shouting or whistling or whatever one ordinarily does to get their dogs attention. Ive never used the beeper as a warning as some do, just as an attention getter.
