[Malinois]

I'd suggest you read up on some operant conditioning information to understand dog training theory.

Basicly in operant conditioning you have positive and negative reinforcment (which increase response) and positive and negative punishment (which decrease response).

You have been given some suggestions which attempt to combine negative punishment (to decrease the response you don't want) with positive reinforcement (to increase the response you want).

Just remember its the dog's perception of the method, not your own, thats important.
