When he has settled down, tug lightly on the lead, show him a cookie, and try to encourage him in coming with you. If he has planted himself so deeply that you swear he is growing roots, switch directions and walk with the buddy dog back past him. Use verbal encouragement and cookies to get him interested in moving, but do not touch him as he will equate your touch with praise. Always end on a positive note. Even if that means that you puppy only walked a few feet.
Persistence is the key.
If you are having trouble lead breaking you puppy, work a little longer each session, several times a day. Eventually, things will get better. Just remember, you will need to be more stubborn than your puppy. If you will be your puppy's trainer, he should realize that your happiness is his responsibility. Although bassets are not picky about their owners, they do tend to have a greater respect for those who keep them happy.
