Well you are right,as far as having a dog come in from behind you,,,if you hunt long enough you will get back-doored, it's part of the deal. Just be ready to not be ready for what will happen sometimes.

As far as scent control, I think it's all in the wind. With the products on the market now, you can fool a deer into thinking you are 400yds. away, when your 40yds away, but you won't do that to a coyote.

Just because you don't see anything does'nt mean you did'nt call anything in. No matter what type of ground you hunt, or what the conditions are, sometimes all you can see is a set of ears, or a flash of a tail.

Most of all learn from your mistakes, don't sacrifice safety, kill dogs, and have a blast doing it.
