As an avid hunter, I have always taken the time to train my dogs properly, and I think I'm pretty good at it. I've had people comment, "How come your dog didn't run out the gate when you opened it?", or "How do you get your dog to 'sit/stay/heel/fetch/come' immediately when you tell him to?"
I just tell them, "From the time they are a 3-month old puppy, I spend 20 minutes every single day going over the basics like 'sit' until they have it down perfectly then I move on to 'stay'. During the 'stay' portion of training I go back over 'sit' a couple times every day, also. It pays off in the end because by the time they are 6-months old you have a well-behaved dog that is actually a pleasure to be around."
I've seen hunters in the field with dogs you just want to shoot because they are completely out of control.
