It is unknown why some dogs exhibit shy behavior and others do not. Theories abound, but most trainers agree that it is ultimately a combination of things that make a dog fearful. Some dogs are born with a fearful nature and others have endured hardships early in life which have contributed to their timid nature. Experts often believe that the fearful characteristic in a canine is a survival mechanism. Perhaps it is a part of the fight or flight response that is believed to be a part of evolution. A dog must know when to fight or when to flee. In some dogs maybe those signals become mixed up and the dog is simply more fearful than others.
Nervousness and fear in dogs occur because of a variety of factors such as breeding and early-life trauma. However, no matter how fearful the canine might appear, with time, love, and training the dog can overcome the behavior and permit the pup to morph into a well-balanced and perfectly adjusted canine. There is no doubt that dogs are highly trainable and can overcome a variety of difficulties when surrounded by a combination of love and patience. The above steps can be taken to actively make your dog feel comfortable and less afraid. Fearfulness is not cured overnight. It does take time but eventually, your dog can conquer the handicap.
