Why Do Certain Sounds Scare Dogs? What To Know About Noise Phobia

It’s normal for dogs to startle when they hear loud noises. But if they continue to be frightened long after the sounds have faded, they may be suffering from noise phobia.

Noise phobias in dogs are extremely common—up to 50% of dogs are affected, according to some estimates. These phobias don’t just make the dogs who suffer from them miserable. They can also lead to injuries, costly property destruction, and damage to the human-animal bond.

What Is Noise Phobia in Dogs?

Being afraid of loud noises helps dogs stay safe in potentially dangerous situations, but sometimes their fear is out of proportion to the true level of danger. This is what sets a noise phobia apart from a simple dislike of loud noises or noise aversion in dogs.

In other words, dogs with noise phobia panic, while dogs with noise aversion are obviously unhappy with the situation but don’t overreact.

Unfortunately, noise phobias have a way of building on themselves. What starts out as a simple dislike of loud noises can turn into a phobia, or a dog who’s triggered by one type of loud noise eventually reacts to many. It doesn’t take many exposures for a dog’s brain to learn to associate loud noises with intense fear.

Common Noises That Scare Dogs

Many of the sounds associated with noise phobias are loud, repetitive, unpredictable, and can’t easily be escaped. For a dog scared of loud sounds, triggers often include:

• Thunderstorms

• Fireworks

• Home or car alarms

• Loud vehicle noises

• Vacuums

What Causes Dogs To Develop Noise Phobias?

Genetics appear to play a role in determining which dogs develop noise phobias. Selective breeding probably explains why certain breeds, such as hunting dogs, have relatively low levels of noise aversion.

However, learning and early socialization are even more important than genetics. Studies have shown that mixed-breed dogs are at highest risk for noise phobias, perhaps because they may spend their early days in less-than-ideal circumstances, while purebred puppies are often raised by breeders who understand the importance of positive early experiences.

Health problems can also be associated with noise phobias. For example, dogs who are in pain seem to be more sensitive to loud noises. Dogs with other behavioral problems, like separation anxiety, also suffer from noise aversion or noise phobia at higher rates.

Symptoms of Noise Phobia in Dogs

A dog with noise phobia will usually display some of the following symptoms:

• Hiding

• Panting

• Pacing

• Whining, howling, or barking

• Drooling

• Destruction of objects in the home

• Attempting to escape

• Peeing or pooping inside the house

The severity of a dog’s noise phobia will determine how bad their symptoms are and how long they last after the triggering sounds have stopped.

Treating Noise Phobia in Dogs

An effective approach to dog noise phobia treatment relies on several different types of care.

1. Environmental Management

While it’s usually impossible to completely eliminate exposure to a dog’s triggering sounds, there’s a lot pet parents can do to reduce the sounds’ intensity and create a soothing environment.

• Design a safe room: An interior room or large closet that doesn’t have windows is ideal, but if your dog already has a preferred place to hide, use that. You can partially block sounds (and light, which is often a trigger for dogs with storm phobias) by hanging thick curtains or covering windows with cardboard or sound-insulating foam.

• Modify your dog’s crate: Crate-trained dogs should already see their crate as a safe spot, but you can make it even more comforting by adding a crate cover, soft bed, engaging toys, favorite treats, and long-lasting chews.

• Increase background noise: Play soothing music, use a noise machine, or run a fan to help block out sounds that scare dogs.

You don’t want to introduce these sorts of changes while your dog is already stressed. Get them comfortable in their safe room and crate when they’re calm.

2. Behavior Modification

There are many behavioral modification techniques that can help dogs learn to relax when faced with loud noises, but the most common approach is to teach dogs to associate scary sounds with something positive.

It’s OK to stay with your dog in their safe room and soothe them when they are afraid. Give them a favorite treat or toy each time they hear a triggering noise, or add a long-lasting treat to their crate.

Your veterinarian or a veterinary behaviorist can put together a comprehensive, individualized behavior modification plan for your dog.

3. Medications, Supplements, and Other Tools

Dogs with severe noise phobias often require treatment with prescription medications. They simply can’t relax enough without them to be open to learning new ways to cope.

• Sileo: a quick-acting, calming gel absorbed through the tissues of the mouth

• Benzodiazepines: alprazolam and similar medications reduce anxiety but need to be given about an hour before a stressful situation

• Trazodone: can be used alone or in combination with other medications to reduce fear

• Anti-anxiety medications: Clomicalm, Reconcile, and other medications given long-term can lower a dog’s overall anxiety level

Nutritional supplements can help in combination with medications or on their own in less severe cases of noise phobias in dogs.

• VetriScience Max Veterinary Strength Calm & Confident Chicken Flavored Supplement Chews: made with colostrum, l-theanine, l-tryptophan, and lemon balm

• Zylkene: contains alpha-casozepine, a calming ingredient found in milk

• Purina Pro Plan Veterinary Diets Calming Care Liver Flavored Powder: contains a probiotic strain that supports calm behavior

Wearables that provide comforting pressure (like a hug) and calming pheromones can also be beneficial.

What Not To Do

The worst thing pet parents can do when a dog has noise phobia is use harsh discipline.

Even though the behaviors associated with noise phobias can be frustrating, any form of punishment—such as yelling, hitting, or using a shock collar—simply reinforces the dog’s fear and will make their noise phobia worse, not better.

Why Is My Dog Suddenly Sensitive to Noise?

Make an appointment with your veterinarian if your dog suddenly becomes sensitive to noise. Underlying health problems could be to blame. And even if this isn’t the case, the sooner treatment for noise aversion or noise phobia begins, the more effective it will be.
