Ok so I finished up force fetch a couple weeks ago and have been working on marks with bumpers since. Well today I started with ducks and he wants to drop them about 5 feet from me and acts really confused when I apply pressure when giving the force command he will mouth the bird but will not pick it up. I went through ff using a buck and bumper before force fetch he did had retrieved dead and live pigeons had very little exposure to ducks. Do I need to go back to the table and teach hold a force again with a bird now or what? This is my first dog to train my buddy that works for a pro has been helping me through ff but I won't be able to get up to their place for a week or so.
