Shaping is an incredibly powerful concept that you should add to your positive reinforcement vocabulary. Shaping is the strategy of rewarding certain behaviors to increase the chances that they will happen again. You shape behaviors of others countless times throughout the day without even possibly realizing what you are doing. If a friend tells a funny story and you laugh, your friend was rewarded for her efforts and will probably tell you a funny story in the future.
Destructive behaviors such as chewing on furniture or digging in the backyard are one form of inappropriate behavior. Demand behaviors are also inappropriate and are another way of describing a dog that is asking for something in a way that is deemed inappropriate. Examples include jumping for attention, play nipping for attention, barking for you to throw the tennis ball, or barking to get let out of the crate.
