What Would Scare A Dog At Night?

Are you worried about what might be scaring your dog at night? Dogs can be easily startled by the slightest of noises, so it’s important to understand what could be causing them to become fearful. In this article, we’ll explore the various things that could be causing your pup to become scared at night, so you can help them feel safe and secure. So, what would scare a dog at night?

Unfamiliar Noises

Noises that are unfamiliar to a dog can be especially frightening at night. Thunderstorms, fireworks, and sirens are all sounds that can cause a dog to become scared.


The loud rumbling of thunder and bright flashes of lightning can be startling for a dog. Dogs may become agitated or anxious during thunderstorms and may try to hide or seek comfort from their owners.


The loud bangs and bright flashes of fireworks can also be frightening for dogs. Dogs may bark, whine, or try to escape when they hear the sound of fireworks. It is important to keep dogs away from fireworks and provide them with a safe place to stay during the night.


The sound of sirens can also startle a dog and cause them to become scared. Sirens from police cars, fire trucks, and ambulances can all be heard at night and may cause a dog to bark or try to escape. It is important for owners to remain calm when their dogs are scared by sirens in order to help them feel safe again.

Unfamiliar People

Dogs are naturally territorial and protective of their owners and their homes. As such, they can become scared when they encounter unfamiliar people or animals. Strangers, intruders, and other animals can all be potential sources of fear for a dog at night.


When a strange person approaches a dog’s home or yard, the dog may become scared and bark or growl to protect its territory. Dogs may also become scared if they encounter a stranger while out on a walk at night.


If an intruder were to enter the home while the dog is sleeping, the sudden noise and unfamiliar presence could startle the animal and cause it to become frightened. Dogs may also become scared if they hear strange noises coming from outside their home at night.

Other Animals

Dogs may also be frightened by other animals that come near their home at night, such as raccoons, opossums, skunks, or even cats. The presence of these animals can trigger a defensive response in the dog as it attempts to protect its territory from potential predators.

Unfamiliar Objects

At night, dogs can be easily startled by unfamiliar objects that they may not have seen during the day. Unexpected movements, strange lights, and unusual shadows can all be enough to scare a dog.

Unexpected Movements

Dogs can be easily startled by sudden movements, such as a person or animal walking by. Even if the movement is from something small like a leaf blowing in the wind, it can still cause a dog to become scared and bark.

Strange Lights

Bright or flashing lights can also scare a dog at night. This could include headlights from cars or flashlights from people walking around outside. Dogs may bark at these lights in an attempt to protect their home and family from potential danger.

Unusual Shadows

Shadows cast by unfamiliar objects can also scare a dog at night. This could include shadows of trees or bushes that look like animals or people. Dogs may bark at these shadows out of fear of the unknown.


Unfamiliar Scents

At night, a dog’s sense of smell is heightened and they are able to pick up on unfamiliar scents that may scare them. These smells can come from new animals in the area, strange smells, or strong odors.

New Animals in the Area

If there are new animals in the area that a dog is not used to, they may be scared by their scent. This could include other dogs, cats, rabbits, raccoons, or any other animal that is not familiar to them.

Strange Smells

A strange smell could also scare a dog at night. This could be something like smoke from a campfire or the smell of food cooking on a grill. It could also be something like an unfamiliar perfume or cologne that someone was wearing earlier in the day.

Strong Odors

Strong odors can also startle and scare a dog at night. This could include strong chemicals like bleach or ammonia, as well as natural odors like skunk spray or rotting garbage. According to the American Veterinary Medical Association, it is important for pet owners to be aware of these smells and try to avoid them if possible to keep their pets safe and calm at night.

Fear of the Dark

Dogs can have a fear of the dark, just like humans. This fear can manifest itself in different ways, such as anxiety in the nighttime or fear of unknowns.

Anxiety in the Nighttime

Dogs may become anxious during nighttime hours due to the lack of light and their inability to see what is around them. This anxiety can be seen through behaviors such as pacing, whining, barking, or even hiding. To help ease this anxiety, owners should provide their dogs with a safe and comfortable space that is well lit and free from any potential triggers.

Fear of Unknowns

Dogs may also be fearful of unknowns that they cannot see in the dark. This could include noises outside or even shadows that may appear to move on their own. To help reduce this fear, owners should try to provide their dogs with a sense of security by talking to them in a soothing voice and providing them with reassurance when needed. Additionally, owners should make sure their dog is up-to-date on all vaccinations and parasite prevention as recommended by the Centers for Disease Control.


Noises, shadows, and other environmental factors can all cause a dog to become scared at night.
