If I could use just one dog training technique apart from clicker training, I would choose “time-out”. It can be used to correct so many behaviours: inappropriate barking, jumping, aggression… Although it clearly shows the dog that his behaviour is not acceptable, it is quite gentle and does not involve physical force. As my readers know, I will never recommend using physical force for correction, because it leads to aggression and damages the relationship between the dog and the owner.
“Time-out” is a very simple technique that even a child can use. It is a type of negative punishment, which means that you punish behaviour by removing something. In this case, you will remove one of the things your dog values most (besides food, of course!): your attention. You will need a light 5 ft. /1.5 m leash and a designated space. The designated space should be isolated from the rest of the house, and you should be able to physically prevent your dog from leaving it. Let’s try.
