Are all dogs afraid of thunderstorms?
Almost all dogs are afraid of loud noises to one degree or another. However, there is a great deal of individual variation. Of the dogs I’ve tended in my adult life one (Zeke) would freak out and try to hide in odd places (e.g. the bathtub), one (Harley) would get nervous and be extra clingy, and our beagle (Nellie) just ignored things like thunderstorms and fireworks.
