Fear of noise is a common fear among dogs. Dogs can be frightened by unexpected loud noises such as thunderstorms or fireworks. The fear of noise can also develop over time if you are repeatedly exposed to loud sounds like sirens and car horns, which may make your dog feel anxious when they hear them in the future.


As you can imagine, younger dogs are more likely to be afraid of loud noises than older ones. This is because puppies haven’t had much experience with the world yet and don’t know how to cope with it. However, dogs often become less scared of new things as they get older. Many people believe this is because they learn from their previous experiences and become desensitized to them (like how an infant may cry when they’re startled or hurt by something but eventually become less frightened).

Another reason why older dogs may not fear loud noises as much has to do with genetics: if their parents weren’t afraid of loud noises, then chances are they won’t be either!


Illness is a common reason for dogs to be fearful of noises. Dogs can suffer from an illness that causes pain and discomfort, so you might think your dog’s reaction to sound is irrational. However, it’s important to realize that animals are not rational like humans. They do not communicate their emotional state very well, so they may react negatively to something completely unrelated because they’re in pain or stressed out.

Why are dogs scared of fireworks? According to virtual pet care services Vetster, “Aversion to noises like fireworks, gunfire, and thunder is one of the most common causes of canine anxiety.” For example, if your dog has been diagnosed with an illness that affects his hearing and eyesight or other senses (i.e., blindness), in that case, he might react fearfully when he hears loud noises, such as thunderstorms or fireworks displays during the summer months.

Another factor affecting noise sensitivity could be a dog’s medical history; if he was abused before being adopted into your family, then this would definitely cause him distress at loud noises reminding him of those events from earlier years!


Genetics can play a part in how dogs react to noise. If you have a dog with certain genetics, it may be more prone to fear noise than others. For example, some breeds are known to be more sensitive or reactive than others and might exhibit different behaviors when exposed to loud sounds.


  • The dog may have been abused or neglected in the past. This can include physical or verbal abuse, as well as neglect and a lack of attention.
  • The dog may be afraid of you due to previous experience with you. If your dog was abused by someone else in your family, then he might be afraid of you because he thinks that you could act like them too.
  • Dogs that are not properly trained can become aggressive toward other dogs and humans, which is why they would also be scared of noises when out on walks with their owners because they don’t know how.

You know that it can be frustrating and upsetting when your dog is scared of something, but remember that all animals are different. So don’t take it personally if they don’t respond to certain situations in the way you expected!
