Dogs, like human babies, can become scared for a variety of reasons. This type of behaviour should not be ignored at any cost. Dogs are creatures that are not dissimilar to humans. Dogs are self-assured creatures, so why is yours suddenly acting scared?

Fearfulness in dogs is a common issue. There are several reasons why your dog is suddenly acting scared. The main reason is that your dog has phobias, such as being afraid of thunderstorms, water, or certain noises. Phobias are irrational and take on their own life.

It can be stressful and frustrating to share your home with a fearful dog. You must first determine the cause of your dog’s fearful and scared behaviour. The following are some of the possible causes of your dog’s fear behaviour.

Reasons why does my dog is acting scared?


There are some things that your dog is afraid of. These are needle phobias, also known as blood injection phobias. This is common in dogs when they go to the veterinarian to get vaccinated.

Fear of strangers is another phobia. After a negative experience, your dog develops a fear of strangers, particularly men. This fear is common in dogs rescued from abusive homes, and it can lead to reactive behaviour.

2.Illness Or Injury

Fear is sometimes just a side effect of a medical problem. If your dog is in physical or mental pain or suffering from an illness, he or she may act scared because they don’t understand what’s going on.

Typically, once the health issue is resolved, your dog will regain confidence.

3.Separation Anxiety

Dogs get so close to their owners in such a short period of time. However, when you are not at home, your dog may become anxious about being alone or without you. When their owner is away, dogs with separation anxiety tend to be destructive.

If your dog starts acting scared when you leave the house, it is most likely due to separation anxiety, which is common in dogs. You’ll need to teach your dog that being alone isn’t necessarily a bad thing.

4.Past Mistreatment Or Abuse

If you really have adopted a scared dog, this could be due to previous abuse or any history that has been done with him in the past, which appears to scare him frequently.

As previously stated, a specific smell, taste, tone of your voice, loud noises, and unexpected accidents such as you stepping on his tail unknowingly can all make your dog terrified.


As dogs age, their reactions to various stimuli change. This is typical after a nap. They appear confused about their surroundings when they wake up after a nap, which causes them to bark or act scared because they are unfamiliar with their surroundings.

6.Loud Noise

If you notice your dog starting to act scared as a result of a lightning storm or the loud noise of fireworks, your dog is probably afraid of high pitched and abrupt noises. It is common for dogs to be afraid of strange or loud noises.

Dogs have extremely acute hearing. They are able to hear things that we as humans are unable to detect. Some dogs act scared when they hear other dogs barking because they are afraid of loud noises such as other dogs barking.

7.Lack Of Socialization

Socialization allows your puppy to become acquainted with the outside world. It is beneficial when your dog is shy around other people or dogs.

However, not all dogs are socialised properly. As a result, your dog may become scared all of a sudden because they haven’t been socialised to something new.

8.Unpleasant Smell

Dogs enjoy smelling things that humans despise and cannot stand the smell of, such as faeces and garbage. Dogs have a high odour tolerance, but there are some odours they cannot stand, such as smoke produced while cooking; they despise the smell of the smoke produced.

Our dogs dislike certain odors, such as liquor, bathroom cleaners, spices, and detergent. These odors make dogs feel uneasy and cause them to behave fearfully. We should keep them away from these odors, which are not only unpleasant but also toxic to them.

9.Uncomfortable Situations

There are some situations in which our dogs do not want to be. These situations are sometimes unavoidable and must be completed despite your dog’s dislike. Certain dogs dislike bathing and try to avoid bathing because they are afraid of water.

Some dogs are afraid of being alone. Isolation in a kennel, crate, or small room can cause anxiety in your dog, leading to fearful behaviour.

10.Insects Or Pests

Certain insects may be frightening to our dogs. This occurs when your dog has a negative encounter with a pest that has previously bitten him, which can cause fear in your dog.

11.Bad Training Methods

It is not always easy to train. It can be difficult if done incorrectly. When new dog owners become frustrated because their dogs do not listen (do not understand) them, they may hit or scold their pup, i.e. use punishment for training.

Hitting and yelling at your dog isn’t good for them. All it does is teach your dog that he should be afraid of you. This is the source of your dog’s fear.

How to calm a crazy dog?

1.Consult The Vet

If you notice your dog acting strangely and for no apparent reason, you should take him to the veterinarian, who will assist you in determining the underlying medical condition.

Cuts or bruises in the paws, broken joints, and other signs of whining, crying, and other destructive behaviour are all possible.

Look for other signs of illness in your dog, such as lethargy, vomiting, diarrhoea, fever, or a lack of appetite.

2.Proper Training

A little training will not only come in handy, but it would also actually assist your dog get used to things he is afraid of.

Maintain your cool and work with a professional trainer to learn how to deal with your dog’s specific behavioural issues.

3.Socialize Your Dog

When your dog is afraid of other dogs or strangers, it is most likely due to a lack of socialisation in his younger years. You should socialise your dog with new people and other dogs to teach them that being around other dogs is not a bad thing.

You can socialise your dog by taking it to public places on a regular basis, taking it to dog parks, and rewarding your dog for good behaviour.

It is not only necessary for your dog to learn that they should not be afraid, but you should also instruct the people around your dog to behave in a certain manner.

4.Dog Proof Your House

Make sure your house is dog-proofed by thoroughly cleaning it. Make sure there is no furniture that your dog might be afraid of. You use insect repellent to keep pests and certain types of insects away from your home.

5.Don’t Punish 

Hitting and yelling will not help your dog overcome his fear of the things he is afraid of. By yelling and hitting your dog, you will teach him to be afraid of you, which is not good.

Use the services of a professional trainer or animal behaviourist to help your dog become accustomed to things he is afraid of, such as loud and sudden noises, unpleasant odours, or pests.

Final Thoughts!

Dogs are social animals, but they can also be scared. The first thing you should do is figure out why your dog is acting scared and then solve the problem.

If you are unable to solve the problem on your own, you must seek the assistance of a professional trainer or an animal behaviourist. However, never punish your dog as this will only make the situation worse for you.
