You just got some GREAT advice. Your pup should be old enough to start right now. Or 2 mos ago for that matter. No such thing as too young but you can burn a pup out keep the sessions short.
I would take this down time from the leg to read Wicks books. That will do you and the dog more good than anything.

The onlything I would add to this isbe sure to add social and obedience training inwith all this. Your dog needs to learn the basics of sitting, heeling and most of all coming on command. I use a check cord and treats for this little job.Any dog training book willhave this. You also need to work on teaching Jr Doggy to load into the box/truck/whatever you will use to haul said doggy. Also takethe pup for rides.Get them used to going on trips, alwaysgive a teat through the cage door AFTER it is closed. Make sure JRknows he has to get inand the door has to shut before he gets a goody. Make shortdrives at first and don't add any other obedience to this don't wear him out with it. Make getting in the box to go for a trip something he REALLY wants to do, that will make your nights go MUCH better. Demand that JR come on command, right now, directly to you.Do this with lots of praise and a scooby snack when he gets there, a sharp tug on his choke chain with the cord when he doesn't.

Obedience will make a fair "grade dog" as they are called....seem like he is much more. A good handling dog is a joy to take out, even on a bad night. If you have never hunted with dogs, especially long ranging dogs like hounds...then you don't have a clue how frustrating it is to spend half the night hunting coons and the other half hunting your dog, or trying to catch and load him. Our fine Walker "Cinch" handles without a lead strap. he will hunt for you, heel for you, and go on to the truck and be waiting in his box if he is told to do so. I wish I could take the credit, but I got him already trained. Someone did a LOT of work with this dog, and it is sure paying off for me.

Good Luck,

Dave
