The Dog Bootie set-I gather up all the Dog Booties I find on the trail into a ziplock bag and use them on the trap line. They smell really really bad. Most have already been pee'd on by every animal they come in contact with. They are all different colors and they all seem to work. This is how I do it.
Just a simple trail set from the back of my crossfox sleigh. My track is 24 inches wide. On long boring straight stretches of my trail, I take a 6 inch nail and hammer it through the Dog Bootie, in the middle of my snow mobile track. Then I set two Alaskan #9 traps, one on each side, 24 inches back from the Dog Bootie and just offset to the left if you are the wolf coming down the trail. The traps are on 15 foot chains with metal drags off the side of the trail. I use a broom to hide the chain and clean it up after setting.The nail keeps it from blowing away or from something trying to snatch it. It is a pee post in the middle of the trail with a very small attractor that they are used to and want to pee on. Simple but effective. I found a bootie one time and used it, it worked and now it's another trick in my bag. The dog mushers are out and leaving them all over the trails. I want the wolf to see it from a distance and walk up to it, not be surprised by it. You don't need to add any more urine. They just get better and better. Your dog will mark them if you want to freshen them up.
Why 24 inches back and offset to the left? I'm trying to use Gulo's advice ("Handedness") and catch them when they plant their LEFT foot, as most wolves are right footed. I don't want them to be able to get their nose on the bootie without passing over the trap. I trap Gulo's old stomping grounds, so why not use his refined methods on his old wolves? Works for me, give it a try.
