For all of my obedience trained dogs I used to use a gradual method to teach food refusal which would take a couple of long lessons, but recently I've learnt of a new which I tried on my kelpie and collie tonight.
Basically, you wait until it's dinnertime then sit down with the bowl of kibble in your lab. Take one peice, offer it to the dog on a flat palm. As soon as the dog moves for it, close your hand.The dog will sniff, paw, lick and maybe offer a few sit and downs. Ignore everything until the dog backs off from the hand, or turns it's head away. Then say "yes!" and open your hand. I've been practising for ten minutes and both dogs will refuse food in my open palm until I say "take it!"
It's a really good lesson in teaching them self control.
