It is a long road ahead. I started my dog at about 8 weeks at the river and keep him on the shore out of the water. Easy till he learned he liked water. A lot. He's a lab. Now his rule is he does not pass me. Also You have to remember that they are just as excited to be out on the river as u at so tough love and some understanding are needed. One other Tip would be to get a 20' lead and attach to your waist to help him learn where u want him to stay.
