Non-associative learning is a change in a response to a stimulus that does not involve associating the presented stimulus with another stimulus or event such as reward or punishment. Habituation is non-associative learning. An example is where a dog that reacts excitedly to a door bell is subjected to repeated ringing without accompanying visitors, and stops reacting to the meaningless stimuli. It becomes habituated to the noise. On the other side of habituation is sensitization. Some dogs' reactions to the stimuli become stronger instead of them habituating to the repeated stimuli or event. Desensitization is the process of pairing positive experiences with an object, person, or situation that causes fear or anxiety. Consistent exposure to the feared object in conjunction with rewards allows the animal to become less stressed, thereby becoming desensitized in the process. This type of training can be effective for dogs who are fearful of fireworks.
A training class is not there to train your dog. Its purpose is to teach you to train your dog so you will need to be committed to train your dog for short sessions (5 minutes) several times a day rather than just simply turn up for classes! This little bit of training everyday will be repaid with a lifetime of living with a well behaved dog. You will also learn to avoid problems before they begin as well as receive help to overcome any that you already have with your dog.
