Many of the unwated behavior that people see in dogs such as diggings or bitting things are a normal dog behavior. Normally trainers try redirecting this type of behavior by having the dog bite on toys instead of chewing on the furnture thus channeling its energy on something practical.
According to Ivan Pavlov (1849-1936), a famous physiologist who discovered condition reflex, said that dogs learned through association. This association is the basis of many dog trainings or modification in today´s market. In Pavlov´s condition reflex, he noticed that the dog salivate during his experiment, a result of the activity of the brain stimuli. In his research, he noticed that when he used the bell at time the dog was being fed, the animal began to salivate upon hearing the sound. Under this concept, the dog can be trained using clicker (sound) and reward it with food, when it performs the expected responses (positive reinforcement) or ignore the dog (negative reforcement) if it did not perform as expected.
