How to train our coon dogs?

we have 2 blue tick coon dogs that are 6 weeks. we want to know how to train them to hunt coons. like what to buy and how to get the scent. we bought a racoon tail from the hunting store but they said theres no scent left on them so how do we get the scent back on it?would raccoon urine work? or would i have to get a roadkill and chop its tail of?
