The ideal scenario would be to have a raccoon carcass or rag saturated with a raccoon scent. Drag the scent from a tree in the area that you expect to be the end of the course, and drag it towards the beginning. This will make sure the trail gets hotter as you move towards the target, and train your coon dog to follow the trail towards raccoons instead of away from them. Start with short, heavily scented paths, and then move on to longer, more complex routes. Always end with your saturated carcass or rag in a tree, teaching the dog that raccoons will go up trees and the dog should stay there until you arrive to shoot. hope this helps
