Everyday common noises and sounds like car horns, blenders, dishwashers and vacuum cleaners are heard so often that human ears are somewhat desensitized to them, but for some dogs, they turn out to be a horrifying experience. This can be the result of a developing phobia or perhaps an unpleasant experience that the dog has encountered earlier in its life that was never corrected. In adopting puppies, it is highly recommended that proper exposure to other people and animals as well as calming any fear of strange, sharp or jarring noises will greatly decrease the likelihood of it developing and exhibiting antisocial behavior.
Dogs exhibit much of the same behavior that children do in the way that an adult may react to a potentially frightening situation. If the person reacts in a fearful way to a loud noise, then a dog that has never been exposed to the same noise is likely to act in a similar manner. It is important not to condone the frightful behavior of a dog when a noise scares it, but to properly expose it to the source. By the owner doing this, the dog will eventually learn not to be frightened by the noise after hearing it again.
Moderation is the key to curing the noise anxiety in dogs. Purchase a CD with the various noises that are known to frighten dogs. Begin by first playing the CD at a low volume, being careful not to invoke excitement in the dog. Each day increase the volume little by little until the dog becomes desensitized by it. Allowing the dog to move at its own pace is recommended in helping it overcome anxiety and its fear of the common noises. Remember to be persistent and reward it for its bravery every step of the way.
