What is positive reinforcement?

By definition: It refers to the introduction of a desirable or pleasant stimulus after the desired behavior, making it likely the behavior will reoccur.  We want to train our dog’s brain and condition it to respond positively to the training experience by giving the dog a reward, for the desired behavior.  For example, the dog sits, he gets a reward, immediately after producing the desired behavior; hence he will be happy to sit because it provides him with a positive reward.
