More than any other type of training, force fetch requires you to be removed emotionally from the task. And that's one weakness I readily admit to. Some dogs pick it up quickly and others have "sticky" mouths, willing to fetch and hold just about anything you require. But some dogs require weeks of work. I do know you should only begin the process if you are darn certain you will follow through. You're asking a lot of your dog and the return should be expected. If I do embark on force fetch training, you can bet I'll use some expert guidance.
