Brittany Relax Dog AromatherapyIs Your Brittany Dog Afraid of Thunder? Fireworks? Your Brittany may be descended from generations of hunting dogs used to the sound of rifles and shotguns, but that doesn't mean your Brittany enjoys loud noises. Hunting dogs are trained to anticipate the crack of a gunshot. They learn that when the human raises a rifle to their shoulder to anticipate the loud noise. But, when it thunders or fireworks pop it is unexpected and can scare your Brittany.
