What Makes Chihuahuas So Fierce?


You have probably seen many videos depicting aggressive Chihuahuas posted on the internet. Some of you have met face-to-face and noticed a dog’s aggression in real life. “Why Are Chihuahuas Aggressive” Should that be its nature? wt online pet supplies will cover all you need to know to understand why Chihuahuas act so aggressively in the following article.

There are a lot of different things that might set off an aggressive behavior in a Chihuahua. When I first met my friend’s Chihuahua, I was greeted with hostile barking and an attempt to bite my heels. It was quite the introduction. One can argue that I was not made to feel welcome.

Whenever I went to see her for the first several months, I was greeted by an obnoxious barking. However, after a series of consistent visits during which I provided her with food, she eventually became more receptive to me, and nine months later, she finally let me touch her (with my buddy was there, of course!). Therefore, I can state from personal experience that Chihuahuas are rude to new people, but once they get to know you and are comfortable with you, they are the sweetest dogs you could ever meet.

1. Chihuahuas are protective of their territory

Chihuahuas make excellent guard dogs because of their innate tendency to watch over their own area and domain with vigilance. When they come into contact with unfamiliar people, whether at home or at a dog park, they immediately become guarded and are prepared to fight if necessary.

Chihuahuas are notoriously possessive of their personal space, so it is best not to approach them while they are snoozing in their preferred location, especially if you are not acquainted with either of you. They have laid claim to that area, and the only people who are permitted to enter there are their owners. They also have a sense of security in that area, and they consider it a violation of the border if an unfamiliar person were to enter there.


I recalled the times when my friend’s Chihuahua would relax on her favorite dog bed tucked away in one of the nooks of the living room. As it was growing darker, I moved in that way to go to the light so that I could switch it on. I was terrified and hurried as quickly as I could into the kitchen when all of a sudden, her Chihuahua jumped up, hissed at me, and snapped at me so loudly that it scared me. That was an unexpected turn of events for me.

The good news is that I’ve picked up on a lot of red flags to keep an eye out for, and I’d want to share them with you so that you can steer clear of situations like this one:

Chihuahua growling

The low-pitched “grrr” sound is the first thing you’ll hear when a Chihuahua begins to growl. You should get some distance between you and them before they start attacking, since this is a warning. If you maintain your position there, the growling they are producing will eventually reach a higher level. Chihuahuas are known to let off a low growl when they are nervous (particularly if you are an unfamiliar face to them), or when they are trying to intimidate you.

Chihuahua showing teeth

After he has tried to frighten you by growling at you, a Chihuahua will begin to flash his fangs in order to complete the process. Another warning sign telling you to back away and not to invade their turf is presenting itself right now. If you disobey them, they will see you as a threat and will begin to attack you and bite you if you don’t comply with their demands.

Chihuahua dog stiff body posture

However, before charging at you, a Chihuahua will assume this rigid body position in preparation for the attack. When a Chihuahua dog displays a rigid body stance, it indicates that he is upset with you and is certain that he will be successful in his confrontation with you.

Eye contact with a dog may be seen as an aggressive gesture, thus the best thing for you to do in this scenario is to steer clear of establishing any eye contact with the Chihuahua. Move away from the Chihuahua in a manner that is slow and quiet.

Chihuahua muzzle punch

In addition to smelling, the snout of a Chihuahua is strong enough to strike the heel or foot of an unfamiliar person before the dog bites.

In my memory, I was attempting to give my friend’s Chihuahua some food. I placed the chicken on my plate before placing it on the ground rather than putting the chicken flesh in her bowl of food. I left the room to allow her some space to take a whiff and start eating, but when I returned, the meal had not been touched at all.

When I stooped down to pick up my plate of chicken and move it to her food bowl, she felt as if I was stealing her of her food, so she became irritated. I tried to explain that I was only trying to help her out. The little dog pursued me around the house and then bit and booped my footwear while they were in my possession. The important takeaway from this is that you shouldn’t tamper with a Chihuahua’s meal!

Chihuahua’s tail stops wagging

The majority of people are aware that a happy dog is one whose tail is wagging. When a Chihuahua perceives that it is in danger or is frightened, the dog’s tail will stop wagging and it will remain motionless.

The position of the tail on a Chihuahua may reveal a great deal about the emotional state of the dog. When they perceive that they are under danger, they become protective and their tails grow more rigid.

2. Chihuahuas are not great with strangers

Chihuahuas have just one person in their life who they adore more than anybody else, and that is their owner. They are very protective of their owners and may growl and snap at anybody they perceive to be an intruder.

As can be seen, Chihuahuas do not take well to strangers, whether they be humans or other canine companions. In point of fact, your Chihuahua may become defensive when confronted with unfamiliar people since he finds new people to be frightening.

Ask your buddy to be patient with your Chihuahua if your friend is going to be coming over regularly. Chihuahuas may be difficult to train. It is usual for Chihuahuas to need some adjustment time before becoming comfortable with your acquaintance. My experience shows that it took up to nine months for a Chihuahua that belonged to a friend of mine to get comfortable with me.

When your Chihuahua is still a puppy, it is in their best interest to be socialized. Your Chihuahua puppy will get the understanding from this that it is OK to meet new people, pets, and locations, and that there is no need for him to be hostile as a result. It is highly recommended that you take your Chihuahua puppy to a dog park at least once a week with other dogs so that he or she can get used to the sight of different pets and people.

Keep in mind that a Chihuahua may resort to violent behavior if they feel threatened by anything. Because this is their natural protection strategy, it is important to socialize them as early as possible so that they don’t react negatively when they encounter other canines, people, or locations.

Advice on how to stop Chihuahuas from behaving in such an aggressive manner:

Bring your Chihuahua to a pet daycare

Taking your Chihuahua to doggy daycare is an excellent approach to socialize him or her. Try to choose a pet daycare that is experienced in taking care of Chihuahuas. Your tiny dog will experience less fear and, as a consequence, less anger as they get more comfortable interacting with new people and other canines.

Ask the pet daycare facility whether they provide the following services for the animals in their care:

  • Playing with other people. Chihuahuas will eventually have the ability to get along with other canine companions. Socialization and play may help your little dog acclimate to the presence of a new, larger dog more quickly. This is especially helpful if you plan to bring home another dog that is on the larger side.
  • Instruction in obedience. Inquire at the childcare facility about whether or not they have any customized sitters who are capable of teaching your Chihuahua new tricks. Your Chihuahua’s ugly, aggressive behavior will be easier to manage as a result of doing this. If possible, limit the number of days per week that your Chihuahua spends at the daycare facility to no more than three. This is due to the fact that Chihuahuas thrive in serene settings.
  • Agility training. Chihuahuas are capable of becoming speedy runners because to their compact size and low body weight. Have your Chihuahua, no matter how tiny, engage in agility training if he or she is a highly active dog. They will be able to create powerful muscles and avoid becoming overweight as a result of this.

3. Chihuahuas with dominant personalities and attitudes

We erroneously believe that Chihuahuas are sweet and adorable due to their little size, which is not the case. However, despite the fact that Chihuahuas are wonderful and friendly dogs, they have a tendency to be bossy. They are courageous and have no fear in showing others that they can be in complete command of the situation.

Be careful to establish your dominance over your Chihuahua pups as soon as they are little. If you do not have enough protection, a Chihuahua will not hesitate to walk all over you if necessary. It is imperative that people who own Chihuahuas raise their young Chihuahuas to have less of a domineering attitude when they are around other people and other animals.

Maintain your composure and a solid stance throughout the workout. Your manner and both physical and verbal instructions will be helpful in teaching your Chihuahua that “no” means “no” when you do this with him.

4. Chihuahuas with anxiety

Chihuahuas that are stressed out are more likely to act aggressively. They will make a loud barking sound as a means of defending themselves and drawing the attention of their owners.

Anxiety may be caused by any of the following in a Chihuahua:

Separation anxiety in Chihuahuas

When left alone for long periods of time, Chihuahuas may develop a condition known as separation anxiety. You’ve undoubtedly seen videos of Chihuahuas sobbing when their owners have to go for work. This is because Chihuahuas adore their owners and want to be with them at all times.

If you work full time and have to leave your Chihuahua at home for more than a few hours at a time, you should make sure to ask your veterinarian or hire a professional Chihuahua trainer to help with your small pooch’s separation anxiety. This is especially important if you have to leave your Chihuahua at home for more than a few hours at a time.

Your Chihuahua may start chewing on furniture, scratching the floor, doors, and toilet paper, and even destroy objects around the home if this anxiety problem isn’t treated soon enough.

You also have the option of enrolling your Chihuahua in doggy daycare, where he or she will interact with other canines and will not be left alone or neglected.

Loud noises can scare your Chihuahua and cause anxiety 

Your small Chihuahua may get frightened by loud sounds such as fireworks, thunder, construction activity, or heavy rain. This information may not come as a surprise to you, but it is still important to know.

If your Chihuahua is afraid of loud sounds, it is important that you discuss treatment options with your veterinarian as soon as possible.

Past traumas

Your Chihuahua’s tendency for aggression may have its roots in traumatic experiences from its past. When they are confronted with memories of a terrifying event from the past, their first reaction will be one of hostility.

Let’s analyze this one in greater detail:

5. Past abuse can affect a Chihuahua’s aggressiveness

Chihuahua dogs, just like people, are susceptible to developing a condition known as post-traumatic stress disorder, or PTSD. If a Chihuahua comes from a home in which he was mistreated, he may have memories of the terrifying and upsetting event he went through as a young dog.

If you are considering giving a Chihuahua a new home via adoption, you should make sure you are aware of who his previous owners and veterinarian were. Because of this, you will have a better understanding of your Chihuahua’s aggressive behavior, and you will also have a better idea of what may cause your new Chihuahua dog to be hostile. This will allow you to avoid any potentially dangerous circumstances.

Helpful Hint: Chihuahuas are notoriously resistant to being groomed, particularly when it comes to having their nails trimmed. When we attempt to cut our Chihuahua’s nails, she cries out like a baby, snaps, and growls at us the whole time. She does a much better job of handling having her nails trimmed now that we have a dog nail grinder that is both quiet and gentle on her paws.

6. Dislike new or unfamiliar places

Chihuahuas are not fond of being moved to unfamiliar environments on a regular basis. They would much rather have the sensation of being safe and protected in their present location. When you move to a new location, you’ll experience new sights, sounds, scents, people, animals, and even new places to call your favorites.

Be careful to gradually familiarize your Chihuahua with his or her new surroundings if you are relocating to a new home or apartment. It’s best not to throw too much fresh information at him all at once. Utilizing a box to create a favorite location for your Chihuahua is a great idea if you have just moved into a new home or apartment. You are free to use crate training on your Chihuahua if that is what it takes to make him or her feel at ease and safe in that location.

By using a movable crate, you may assist your Chihuahua feel more at ease and comfortable when you are travelling. Make sure you have one on available and spend some time with your Chihuahua in it before you move. This will help your dog feel more at ease.

7. Health Problems in Chihuahuas

Chihuahuas are prone to a number of different health issues that are rather prevalent. Unlike humans, our Chihuahuas do not make the same facial expressions or vocalizations when they are in discomfort. The behavior is typical of dogs. They have had to become courageous over the course of many generations in order to avoid being eaten by their enemies.

Since of this, it is quite challenging for people who own Chihuahuas because the owners don’t realize there is an issue with their dog’s health until it is too late, when their teeny adorable doggie is in excruciating agony.

Helpful Hint: Chihuahuas are prone to a number of health problems, which we detailed in our guide titled “Chihuahua Health Issues: Complete Guide.” In this guide, we also included a list of these health problems.

It is essential for owners of Chihuahuas to obtain pet insurance since these dogs are predisposed to a number of different health problems. Alterations in a dog’s demeanor may be brought on by the sudden onset of health issues, which can occur at any moment.

If you attempt to pet them in an area that is damaged or that hurts, they may respond by becoming hostile, such as exposing their teeth, barking, or biting.

If you have noticed a change in your Chihuahua’s behavior, such as increased howling or whining, we strongly suggest that you take him or her to the veterinarian as soon as possible for a comprehensive examination to rule out any potential health issues.

Why are Chihuahuas so mean?

It’s possible that your Chihuahuas’ bad behavior is the result of hormonal shifts. If you own a female Chihuahua, you should inquire with your veterinarian on whether or not spaying her would be beneficial. If, on the other hand, you own a male Chihuahua dog but have no intention of reproducing it, you may want to think about having it neutered in order to reduce the amount of aggression it displays.

Chihuahuas have the potential to be vicious if they are denied the opportunity to procreate when they are in the mood to do so. This may occur if you have a large number of pets in your household. If you do have more than one dog in your household, spaying or neutering may be something you want to give some thought to. This way, you won’t be taken aback by an unexpected litter of Chihuahua pups that you don’t want.

Chihuahuas have a reputation for being particularly vicious for a number of other, less obvious reasons as well. Let’s have a look at some of the reasons why people have such a negative perception about Chihuahuas.

Chihuahua’s small size 

Chihuahuas can give the impression of being quite hostile toward strangers. Chihuahuas are little canines, which means that everyone and everything they encounter looks to be larger and bigger than they are. This is why they have this perception. They may experience feelings of intimidation, menace, nervousness, or anxiety as a result of this worldview.

As a result of this, Chihuahuas could resort to aggressive behavior in order to protect themselves. When Chihuahuas go into defense mode, you’ll be able to tell because their actions begin to resemble those of predators. As a result, they give off the impression of being cruel, aggressive, and impolite despite the fact that they are little dogs who seem sweet and friendly.

Lack of socialization and training in Chihuahuas

It is best for parents of Chihuahua pups to begin early training and socialization of their canine companions. The period of time between 7 and 16 weeks of life is considered to be the most formative for socializing. This is due to the fact that socializing Chihuahua pups with other pets in the home, other dogs (both large and tiny), and even strangers is much simpler while the canines are still in the puppy stage. This will desensitize them and help them get used to seeing and meeting new people as well as other pets and animals.

We strongly advise people who own Chihuahuas to socialize their puppies with other dogs and people while they are young so that their canines will mature into well-mannered adults who won’t be aggressive toward other animals or people.

Sometimes owners of Chihuahuas wind up being too indulgent toward their little dogs because they consider them to be adorable and lovely. The majority of the time, Chihuahua dogs do end up getting their way since it may appear innocuous to the owners, and some owners don’t make any effort at all to teach their Chihuahuas.

Are chihuahuas aggressive?

Chihuahuas have a reputation for being hostile because they are very protective of their owners and the space they call their home, both of which they guard with their lives. When they are threatened or feel the need to defend themselves, animals may often resort to more aggressive behavior such as baring their teeth, snarling, barking, or biting as a means of self-defense.

On the other hand, when the Chihuahua becomes used to your presence, you’ll recognize how kind and affectionate they really are. When there is a Chihuahua in the vicinity, it is essential for any new people to have a level head and a patient demeanor.

Chihuahua owners also have the option of purchasing a muzzle for their pet in the event that an unfamiliar guest will be arriving at their home. However, you will have the best success with this method if you have already muzzle trained your Chihuahua. Ensure that the muzzle you choose is suitable for your tiny dog as well as comfy for him to wear.
