But if the dog will not release the bite after a few hits then the helper needs to freeze and stop the fight. The handler needs to physically take the dog off the sleeve and repeat the exercise in a manner that allows the dog to be controlled. If this means a long line or electric collar then that s what has happen. When the dog comes in and bites it wants a fight, it needs to learn that the only fight its going to get is when the helper attacks or trys to flee. This is where the helper lets the sleeve go dead and removes the fight from the process.
Most tough dogs prefer the fight.
If the training is done properly this does not have to become a big issue. The key point in training is to give the bite when the dog barks in a strong defensive bark. New trainers often make a mistake and expect long barking sessions out of a dog - this is not correct. The dog only needs to bark hard 3 or 4 time for the helper to move and give a bite. The dog needs to learn that the fight and bite come from intensity and not a certain duration of barking.
