Deafening thunder can be a little scary even for a full-grown human who knows it’s harmless, so your dog’s terror is understandable. But why exactly do thunderstorms send so many of our pawed pals into a tailspin?
Many dogs are distressed by unexpected loud noises—a condition known as noise aversion, or noise phobia in more severe cases—and sudden thunderclaps fall into that category. What separates a wailing siren or fireworks show from a thunderstorm in a dog's mind, however, is that dogs may actually realize a thunderstorm is coming.
As National Geographic explains, not only can dogs easily see when the sky gets dark and feel when the wind picks up, but they can also perceive the shift in barometric pressure that occurs before a storm. The anxiety of knowing loud noise is on its way may upset your dog as much as the noise itself.
Static electricity could also add to this anxiety, especially for dogs with long and/or thick hair. Tufts University veterinary behaviorist Nicholas Dodman, who also co-founded the Center for Canine Behavior Studies, told National Geographic that a static shock when brushing up against metal may heighten your dog’s agitation during a storm.
It’s difficult to nail down why each dog despises thunderstorms. As Purina points out, one could simply be thrown off by a break from routine, while another may be most troubled by the lightning. In any case, there are ways to help calm your stressed pet.
If your dog’s favorite spot during a storm is in the bathroom, they could be trying to stay near smooth, static-less surfaces for fear of getting shocked. Suiting them up in an anti-static jacket or petting them down with anti-static dryer sheets may help.
You can also make a safe haven for your pup where they’ll be oblivious to signs of a storm. Purina behavior research scientist Ragen T.S. McGowan suggests draping a blanket over their crate, which can help muffle noise. For dogs that don’t use (or like) crates, a cozy room with drawn blinds and a white noise machine can work instead.
Consulting your veterinarian is a good idea, too; if your dog’s thunderstorm-related stress is really causing issues, an anti-anxiety prescription could be the best option.
