Outside, the first clap of thunder rumbles, and even before the first flash of lightning, your dog is already a different animal: he’s trembling, panting, clinging to your leg, or hiding behind the sofa. For many dogs, a thunderstorm is pure stress. And for you, as the owner, it’s almost unbearable to see your pet so distraught.
Is your dog scared of thunderstorms right now, and are you wondering how you can help him? Then you've come to the right place. We'll show you how to recognize the signs of fear, what to do immediately when a thunderstorm hits, and how to help your dog overcome his fear of thunderstorms over time.
How can I tell if my dog is afraid of thunderstorms?
Fear during thunderstorms manifests itself slightly differently in every dog. Some become very quiet and withdraw, while others get hyperactive and constantly seek your company. It’s important to recognize these signs early on, so you can respond before their anxiety turns into full-blown panic.
Typical signs of a fear of thunderstorms include:
- Shivering and panting, even though it's neither cold nor hot
- Hiding: behind the sofa, in the bathroom, in the darkest corner
- Affection: Your dog never leaves your side
- Restlessness: Pacing back and forth, unable to settle down
- Barking or whimperingat every clap of thunder
- Drooling, yawning, tail tucked between the legs
- In severe cases,panic: hyperventilation, frantic flight, destructive behavior
A single sign doesn't necessarily mean your dog is severely afraid. However, if several of these signs occur together during every thunderstorm, your dog is clearly distressed by the situation.
Why are dogs afraid of thunderstorms in the first place?
A thunderstorm is a full-blown emergency for a dog’s sensitive body. The thunder is loud and unpredictable, the lightning flashes brightly, and the ground vibrates. Added to that is something we humans barely notice: the change in the air.
Dogs react to the dropping air pressure, static electricity, and the smell of ozone before a thunderstorm. Some even experience mild electric shocks through their fur, which can further intensify their fear. Often, this is also based on past experience: A dog that has been startled during a thunderstorm once associates the rumbling with danger. And puppies that have never had the chance to become familiar with thunderstorms in a calm setting are more likely to develop this fear.
Can dogs sense a thunderstorm coming?
Yes, most dogs can sense a thunderstorm long before we hear the first clap of thunder. That's exactly why your dog often gets restless even when the sky is still almost blue.
His hearing is much more sensitive than yours; he picks up on low frequencies and distant rumblings sooner. He also senses dropping air pressure and static electricity. This early warning isn’t bad news—on the contrary: You can use his early restlessness as your own personal warning sign and help your dog before the storm really kicks in.
What can I do right away if my dog is afraid of thunderstorms?
In an emergency situation, there are two key things to focus on: providing reassurance and distracting your dog. Your dog needs to feel safe and secure, and he needs something to divert his attention away from the thunder.
These immediate steps help most dogs:
- Stay calm yourself.Your dog picks up on your mood. If you stay calm, you give him a sense of security.
- Create a safe haven.A blanket over the crate, a corner in the windowless bathroom, a cozy den. Let your dog choose for itself where it feels safest.
- Drown out the noise.Soft music, the TV, or a fan can muffle the thunder and make it seem less threatening.
- Just be there.Physical closeness, gentle strokes, and your voice are all allowed. You won’t make the fear worse by doing so (more on this below).
- Distract him by having him lick and chew.Nothing calms a stressed-out dog as reliably as gentle licking.
The quickest practical tip from our workshop: Apply CBD to the licking mat
Our favorite trick for those urgent moments combines two things at once: Put some CBD oil or CBD paste directly onto a licking mat. The CBD is absorbed particularly quickly through the oral mucosa—faster than if it had to go through the stomach. And the act of licking itself has a calming effect because it keeps your dog occupied and helps relieve tension.
Here’s how to turn a stressful moment into a little oasis of calm: Your dog will focus on licking instead of the thunder. If a sudden thunderstorm rolls in that you didn’t see coming, a treat or some mus is the quickest solution. A tip from our community sums it up perfectly:
"She's hardly afraid anymore—only when there are really loud noises. But even then, she's easily distracted. That wasn't possible before."
— Claire H.
Things You Should Avoid If You're Afraid of Thunderstorms
Let's dispel a persistent myth: You can comfort your dog during a thunderstorm without reinforcing its fear. Fear is an emotion, not a learned behavior. Calm closeness relieves stress; it does not reward panic.
What really harms your dog, on the other hand:
- You’ll end up feeling nervous or flustered yourself.Your tension is immediately contagious.
- Don't punish or scold him when he hides or barks. That just makes him more afraid.
- Forcing someone to walk the dog while it's lightning and thundering.
- Don't express sympathy in an overly effusive waywith a high-pitched, excited voice. It's better to stay calm and natural.
How can I help my dog overcome his fear of thunderstorms for the long term?
Immediate help gets you through the moment. To help your dog eventually become more relaxed during thunderstorms, it’s worth doing some calm training over the course of several weeks. The goal: to help your dog lose its fear of thunder.
-
Play the sounds of a thunderstorm at a low volume.
There are pre-recorded thunderclap sounds available. Start with the volume very low—so low that your dog barely reacts.
-
Make Positive Connections
While the sounds are playing, there are treats, a game, or some petting. From now on, thunder means something nice is about to happen.
-
Slowly increase the volume.
Only if your dog stays relaxed should you gradually turn up the volume a little at a time. If he seems scared, turn it back down.
-
Set up a relaxation signal.
If your dog associates a specific ritual with calm—such as a certain blanket or a particular scent—you can use that cue during an actual thunderstorm.
Our Relax Buddy is a great training tool for conditioned relaxation—to help you calm down in stressful situations, such as thunderstorms. In conditioned relaxation, a signal, object, or scent is associated with a relaxed state and can be deliberately triggered when needed. Once you’ve reliably established conditioned relaxation, you can use it to counteract potential triggers.
This noise training takes patience, but it has lasting effects. Important: Don’t overdo it. It’s better to have short, calm sessions than one long one that overwhelms your dog. You can find out exactly how to do it in our article. If your dog has already developed a severe panic reaction or phobia, seek support from experienced dog trainers or a behavior consultant who can guide you through the training process.
Should I leave my dog alone during a thunderstorm?
If possible: no. A dog that’s afraid of thunderstorms feels even more helpless when left alone, and if it panics, it could hurt itself or damage the apartment. On days when there are thunderstorms, make sure someone is there with it.
You should also adjust your dog’s walk schedule. Take your dog outside before the thunderstorm rolls in. When there’s lightning and thunder, indoors is the safest place anyway. If he absolutely has to go outside, keep it short and keep him on a leash so he doesn’t run away in a panic.
Why is my dog suddenly afraid of thunderstorms?
Some dogs remain calm during thunderstorms for years, only to suddenly become afraid. There is almost always a trigger behind this.
Often, it’s a single bad experience—a particularly hard blow at the wrong time. For older dogs, declining hearing or vision can make the world seem more unpredictable, which can trigger anxiety. Pain or discomfort can also lower their tolerance for stimuli. If anxiety strikes suddenly and intensely, it’s worth scheduling a health checkup at your veterinarian’s office to rule out any physical causes.
What about medication or homeopathy for fear of thunderstorms?
For very severe panic attacks, there are veterinary medications that can provide short-term relief. These should be administered by a qualified professional and are a matter for your veterinarian—not for self-medication. Some pet owners use homeopathic remedies, but experiences with these vary widely.
Many dog owners also turn to natural remedies to help their dogs cope with stress. This is exactly where CBD can be a gentle solution.
How can CBD help your dog cope with thunderstorm anxiety?
CBD is a natural compound derived from the hemp plant. It does not make your dog “high.” You can think of CBD as a sort of“body police”: It supports the body’s own system responsible for balance and relaxation—the endocannabinoid system.
If your dog is afraid of thunderstorms, CBD can help him calm down more quickly without making him tired or drowsy. How you give it is a matter of preference, and it can be easily combined with other things:
- CBD oil or CBD paste on a licking mat: rapid absorption through the oral mucosa, plus the distraction of licking. Our favorite for immediate relief.
- CBD Snacks: Great for a quick snack.
- Herbal blends like "Less Stress": a gentle source of support on days when you know you'll be stressed.
As a general guideline, we recommend 0.5 to 1 mg of CBD per kilogram of body weight, spread out over the course of the day. In acute stressful situations, such as a thunderstorm, the dose may be three to four times that amount. CBD works best when a baseline level has already been established.
A pet owner from our community describes what that can feel like as follows:
"Bambam no longer starts to tremble in scary situations."
— Tanja H.
