Almost all vets agree that positive reinforcement training is the most effective method of dog training. Positive reinforcement training essentially focuses on rewarding your pet for good behavior, rather than punishing bad behavior.

The problem is that using only positive reinforcement does not work on all dogs and can actually cause behaviors to become worse, or in some cases much worse.

Negative punishment is when you take away a desired stimulus after a undesired behavior is performed making the behavior less likely to happen in the future. For example you are walking your dog and they start to pull, You stop walking and wait till your dog stops pulling.

Dogs respond best to praise—and food or toys. Positive reinforcement training uses a reward for desired behaviors. Because the reward makes them more likely to repeat the behavior, positive reinforcement is one of your most powerful tools for shaping or changing your dog's behavior.
