Huge Difference between a dove and a goose.

If someone asks you to pick up a 5 lb weight, you probably wouldnt hesitate. What if they asked you to pick up a 100 lb weight, you might be a little more reluctant...

A goose is a big heavy bird. Put 25 lbs in your mouth and run around the yard, see what the dog has to do. Many many dogs have trouble with geese, you have to get a dead goose, have someone else toss him and release your dog. When they get to the bird, they may try to pick it up or may just stare at it a minute and come back to you.

FF is for dogs that are not retrieveing on their own. If your dog has the drive to fetch over and over all day, then FF isnt necessary. You just have to be consistent when your training hold. Get a heavy bumper, biggest heaviest you can find, or better yet, a Dead-fowl goose. Teach the dog to "hold" this, carry it around the yard/house fora few days. Then have a buddy throw that sucker and see if the dog will pick it up, if not, re-toss and re-send, over and over until it is picked up. sneak in a real goose before you stop. Just remember what the dog is going through, physically and mentally, with a goose. Wounded geese can hurt dogs, you need to teach the dog to handle wounded ducks/ geese. Do this with a live bird, wings clipped or tied.

Good luck.
