I agree with the use of the wing on a string for young pups and only to show "Pointing Instinct".I don't beileve it will help in steadying a dog as live birds will.I also don't like to use scent.Its very easy to use "To" much scent making it more difficult later for the dog to scent birds under regular hunting conditions.If you use scent and the dogs getting a whole snoot full of scent then when you take to the field its very possible the dog could miss birds or have to get extremely close because its used to getting SO much strong scent from the bottle scent then the actual scent cone being released from live birds.Its just my opinion that the mysterious world of scent is difficult enough to figure out then to start off by using bottle scent.Birds,Birds and More Birds is the answer,Like someone said should you have to use a game preserve.So be it.Bird contacts are what any dog really needs.Happy Holidays,Jackson...
