Hi, if they are close enough, your best bet would be to talk to the breeder, and get them to show you. If they are too far away to help you need a training club, and join your local Cocker Club too. You often find a pup will be tense on the table at first, and they often try to roach a little. Work on getting the pup relaxed and happy on the table, first just playing with him and giving tidbits. Then start stacking briefly, working of the leg positioning, and ignore the top line, it should relax and slope into position as the pup gets happier with the pose. A lot of American trainers use cans, or things called "happy legs" to teach the pup to put its legs into the right position. this is hard to explain without having the pup here to show you. If you cant get help from your breeder let me know and I will try & put you in touch with someone in your state.
