if you are using a canvas drag you put the sent on the dragand store it in a ziplock bag . and when you drag a piece of hide it is still stronger at the finish . the drag works the same way . the animal smells the same all the time and the further it gets from point [A] the weaker the sent is at point [ A ] . but i just use a piece of hide stored in the freezer for pigs . the sent will be powerfull at a wallow and get stronger leaving the wallow and weaker coming into the wallow . much like using the canvas drags and sents . a dog with any hunt smarts will figure this out quick , some knuckle heads will take longer .
x2...need to simulate hunting conditions...otherwise will be teaching dog to back track.
