as you already know I'm sure, obiedience training takes place from day one and is reinforced every time you do anything or say anything to your dog. I mostly work with bird dogs but also trained 2 blue heelers for agility competitions and a couple of ankle biters...but the principles are the same. I train dogs to react/respond to hand signals....This, I have found, forces the dog to look at you and react......instead of listening for a verbal command...Sit=index finger pointing up...down=index finger pointed straight down...here=index finger pointing up then swings down to point at the ground....stay=open hand palm facing the dog...heel=open hand thumb tucked in facing the dog...I use NO verbal commands with these hand signals...there are verbal commands but they are used only when I'm behind the dog....they are on point....or they are out of my sight....hunting dogs cast to the left or right by raising the left/right arm and moving slightly in that direction.....You say" My dog won't pay attention to my hand signals."....They probably won't at first...DO NOT start yelling at them...they will learn that you will repeat your commands if they play stupid....start in the house...start small...they won't look at you? Put some peanut butter on your finger...I bet they won't take their eyes off you...soon they learn the hand signals because they can't help it...start with the sit signal...let them lick a little PB off your finger to reaquire their attention.....The day you go to the show, I tell the owners that I train for, put the PB on your little finger and keep it tucked in...the dog knows it is there...good luck
