RE: Eating the bird!
NO!
What your doing is called "Yanking the dog back to you with a CC"..
Force Fetch is am enormous subject, cant possible cover it on a forum. You need to get Smarkwork by Evan Graham.
FF is a foundation for reliable retrieves under any circumstances, your imposing your will upon the dog, forcing him not to refuse a "Fetch" command.
FOR THE LOVE OF GOD! Get yourself a training system ASAP!!
