What may be going on

• Storm or noise fear. Cornell says signs of fear range from mild to severe and include trembling, vocalizing, panting, pacing, drooling, hiding, digging at doors and escape attempts.
• The cues start early. PetMD says storm phobia is a response to clues that appear even before a storm arrives: darkening skies, rain, gusts of wind, the scent of ozone and changes in barometric pressure.
• A health problem. PetMD says your vet will need to rule out conditions that can cause similar behavior, such as separation anxiety, pain and neurological problems, and that an underlying health problem can make a dog suddenly fearful of storms.
• How the fear develops. Cornell lists a negative experience around a specific noise, lack of early socialization as a puppy, underlying illness, and worsening anxieties with age.

What to do

1. Book a vet visit if the barking is new or sudden. PetMD says pain and other health problems can look like storm fear.
2. Make a safe space. Cornell says to choose a familiar spot with a cozy bed or blankets, in a room farthest from the noise with few or no windows. It says to use a crate only if your dog is already used to it and sees it as a safe spot. VCA suggests a well-curtained or blacked-out room, closed windows and doors, and company for the dog.
3. Cover the sound. Cornell says to play white noise and music, and that layering two different types of sound can help drown out the noise.
4. Give something to do. Cornell suggests long-lasting treats such as stuffed frozen Kongs, lick mats or other food toys.
5. Plan the day. Cornell says to exercise or play outside earlier in the day, and to plan bathroom breaks so you aren't going outside after a storm starts. If you must go out, it says to use a leash even in a fenced yard.
6. Keep your dog safe. Cornell says frightened dogs may try to flee, so keep the ID collar and microchip information current and secure your home and yard. VCA says even a placid dog can behave unpredictably when frightened by noise.
7. Never punish the barking. Cornell, VCA and PetMD all say punishment makes the fear worse.
8. Ask your vet about a long-term plan. Cornell says to ask about anti-anxiety medication well in advance, and VCA describes retraining programs that are best started when storms are not likely. Neither is something to start without your vet.

Common questions

Why does my dog bark at night only when it rains?

None of the pages we opened explain rain-only night barking directly, so we can't say for sure. The closest match is storm fear. PetMD says storm phobia is a fear response to clues that appear even before a storm arrives, such as darkening skies, rain, gusts of wind, the scent of ozone and changes in barometric pressure, and it lists excessive vocalization among the signs.

Is fear of storms common in dogs?

Cornell's Riney Canine Health Center says the sounds from fireworks, thunderstorms and other loud noises are common sources of fear and anxiety in many dogs.

Can fear of storms start suddenly?

PetMD says a dog with an underlying health problem (pain, an internal issue, a heart issue, a neurological issue or dementia) may suddenly develop behavior problems and fear of storms. Cornell lists underlying illness and worsening anxiety with age as possible reasons a noise fear develops. A vet visit is a sensible first step.

Should I comfort my dog during a storm?

The sources differ. VCA says not to fuss, pet or try to reassure a scared dog, because the dog may treat that as a reward for the behavior. Cornell says to stay home to comfort your dog, because many dogs with noise phobias also have some separation anxiety. All three sources agree on one point: never punish a scared dog. Ask your vet which approach fits your dog.

Can medication help with storm fear?

Cornell says to talk to your veterinarian about anti-anxiety medications well in advance and to trial any medication first on a day without noise. VCA says drugs should only be given under veterinary supervision and must be active in the body before the noise starts, usually at least an hour before. Do not give your dog any medication without your vet's guidance.
