How many times have you watched someone repeat a command several times while their dog pretended to be completely deaf? Have you done this yourself? Saying "come" over and over, until you sound like a broken record, is a sure sign that you've forgotten one of the principles of training. If a behavior works for him, he will repeat that behavior. If it doesn't work he will try something else.
Here's a lady in the store with a couple of young children. The kids are grabbing things off the shelves. She keeps telling them "Don't touch that." They keep ignoring her and grabbing more stuff off the shelves. Finally, after telling them about ten times, Momma gets a little frustrated and tells them "Don't touch that!!!" The kids know the game is up by her change in attitude and suddenly they understand what "Don't touch" means.
Funny thing is, next time she takes the kids to the store she has to tell them ten times before they listen. That's because she made the mistake of telling them ten times last time. They know she'll tell them ten times before they'll have to do it . She's taught them to expect her to tell them ten times. Your dog will learn this lesson with amazing speed.
If you ever want your dog to obey on the first command, don't fall into the trap of repeating a command and doing nothing while he ignores you. Give the command once, and if he doesn't respond, go to him, take him by the collar. Now repeat the command and physically help him obey. If you never repeat a command without using the collar, he will come to the conclusion that he might as well obey the first time so as to take advantage of your good nature.
Good luck with your training
