If there are no other phobias involved, this fear can often be easily fixed simply by bringing a dog to the vet for a few social visits that don't involve an examination.

    It may surprise people to learn that it is fairly common for dogs to be afraid of men. While in some cases this fear may stem from being abused by a man, most of the time it is due to lack of socialization. Dogs who are fearful of men should be slowly desensitized to men in a non-threatening manner. Keep in mind that a fearful dog may growl, snap, or bite someone as a result of this fear.
