As young dogs and puppies deal successfully with fears, they will become generally less fearful. Each time they conquer a problem, they gain confidence in their abilities and in you. Instead, they are cautious and careful. When these characteristics are coupled with a lack of confidence, the dog can become very unhappy when he is in a strange situation. For these dogs, obedience training is a godsend.
Confident dogs can reach into their bag of tricks and find a way to deal with the unusual.
The structure provided by obedience training gives the less confident dog a prescribed method for handing stressful situations. As he does so, his confidence in his abilities increases, and he becomes less anxious.
