Some people say that Chihuahuas are more dangerous than Pit Bulls…!? So, is that really the case, and are they truly dangerous small dogs?
Keep reading as we break down everything you need to know about your favorite pup’s behavior in these 7 points in our latest blog post 😉!

Are Chihuahuas Dangerous?
Chihuahuas are not inherently dangerous or aggressive.
Like all dogs, they can pick up bad habits or become aggressive due to inadequate care, lack of training, or mistreatment.
To have a well-behaved Chihuahua, you need to understand the reasons behind their aggression, and we are going to explore them below!
1. Chihuahuas are Naturally Wary

One of the most common causes of aggression in Chihuahuas is fear. They are generally wary of new people and new animals.
This natural wariness is a survival instinct. The presence of a new person or animal could be perceived as a threat.
Caution is an inherent character trait of your pet. The important thing is to teach them not to express it through aggression.
A fearful dog might not show their teeth or growl to warn the victim. In such situations, the only warning is the dog’s fearful posture and their attempts to retreat.
It is essential to learn what your Chihuahua does before becoming aggressive. This will help you identify when they are about to act out, though this is rarely seen in puppies. 😜
2. Chihuahuas are Protective

Chihuahuas can be both protective and territorial. This is closely linked to their natural wariness.
All dogs, regardless of breed, can take on the role of “protector.” This is sometimes referred to as being the “leader” or “alpha.”
Your Chihuahua will take on the protector role if they feel you need protection. It is essential to show them that you are the one who protects them!
Obedience training is a great way to teach your Chihuahua that you are the boss.
It is essential to get your dog to listen to you and not react to other stimuli; the more your dog listens to you, the more they will trust you. 😊
👉 Positive Reinforcement
Positive reinforcement training is much more effective than punishment.
Warning: It is important to never physically punish your small dog. This will only teach them to be wary of you, and that is not what you want…
Focus instead on teaching (training, education) and rewarding good habits. Teach them words like “no” and “bad” when your Chihuahua disobeys.
Focus on correction, not punishment. If you encounter many difficulties in training your little love or in case of serious aggression, consult your veterinarian or a specialized dog trainer.
3. The Chihuahua is a Loyal Little Dog

Once you have earned the trust and cooperation of your Chihuahua, they will be loyal; however:
In this canine breed, loyalty can quickly turn into territorial aggression.
Socialization helps minimize territorial attitudes and will also help manage their wariness.
Your pup must be open to new people, new animals, and new places, otherwise, they will struggle to accept novelty at home.
There are many ways to socialize your little companion:
- Schedule playdates.
- Take them for walks in popular neighborhoods.
- Take them to dog parks with enclosures for small dogs.
- Take them to restaurants with dog-friendly terraces.
- Introduce them regularly to friends, family members, and other dog breeds.
Besides socialization, you can also set boundaries, for example, by not allowing your dog to approach others before you do.
Ask them to sit and stay when they answer the door.
You are the one in charge and you set the rules 😇 NOT THEM.

4. Chihuahuas have “Small Dog Syndrome”
Your Chihuahua is not fragile and wants to prove it to you!
Small dog syndrome is defined as follows:
“A set of behaviors displayed by small dogs, behaviors that have the effect of overcoming deficits caused by their small size.”
Here are some examples of these behaviors:
- Pulling on the leash.
- Stubbornness.
- Reactive barking.
- Jumping on people.
- Excessive growling.
- Confrontational attitude.
But fortunately…
Small dog syndrome can quickly become a thing of the past thanks to training and good socialization.
It all comes down to showing your Chihuahua that you are the protector and the boss! 😉
Here are some keys to teaching better habits to your Chihuahua and making them less aggressive:
- Patience
- Repetition
- Perseverance
Establishing a daily training routine can work wonders. Plus, it gives your little companion an activity they can look forward to every day! 🐶
5. Chihuahuas are Communicative

Aggression is often a sign of poor upbringing or a lack of training.
However, it may be that your pup is aggressive as a means of communication.
A dog cannot express themselves the same way a human can, and when they are in pain, they must find a way to let us know (like barking 😜).
Dogs generally warn us of pain by whining (barking), and sometimes we misunderstand these signals and touch or aggravate the painful area.
And this can lead our dogs to lash out at us.
It is important not to leave your Chihuahua’s aggression unanswered. It is also important not to teach our dogs that communicating pain is bad.
In this case, a visit to the vet is the best solution.
If you cannot get to a vet immediately, try to calm your little furball by petting them in other areas (you will need their utmost trust to be able to investigate).
Regarding aggression, scold them firmly but calmly. Remember that they are acting out of pain, not disobedience.
6. The Chihuahua has Mood Swings

Chihuahuas may be fierce, but they are also sensitive creatures. 🥰
Chihuahuas are intelligent and very aware of their surroundings. Changes in their environment can cause mood swings.
This can include:
- New smells.
- New or loud noises.
- Rearranging the space.
- The absence of a person or animal they are used to.
Just like humans, Chihuahuas can react negatively to change. This can result in aggressive or depressed mood swings.
Chihuahuas are homebodies.
When a change occurs, it is important to help them acclimate.
If your dog feels down, a little extra attention or a special treat here and there can help, and don’t forget that a long walk will always do them good (and you too).
Any health problem can also lead to mood swings in your Chihuahua and make them more restless
You should be attentive to mood changes that have no apparent cause:
- Lack of focus.
- Loss of appetite.
- Excessive licking.
- Irregular bowel movements.
Of course, if you think your 4-legged love is suffering from a health issue, contact your vet quickly for a physical exam.
7. The Chihuahua is not a Fan of Teasing

Teasing Chihuahuas can be a comical practice, especially when they have original and dramatic reactions.
And you know it well… It is easy to push things too far and deliberately upset or anger your dog… 😅
It’s unfair to them! No one likes being teased relentlessly.
Furthermore, if you push them too far and then punish them, it will only teach them to fear you.
So, training your dog will only become more difficult…
Chihuahuas do not have the same reasoning capacity as humans and cannot understand a joke like you do.
Here are some examples of bad teasing:
- Blowing in their face.
- Pushing or touching them repeatedly.
- Offering them treats and snatching them away.
There are many ways to play with Chihuahuas, and deliberately making them angry should not be one of them.
A good alternative to teasing is teaching your Chihuahua to play games! They will be delighted! 😊
Final Paw
Aggression in Chihuahuas is no laughing matter, but forget the muzzle for your dog.
However, your small dog does not deserve this bad reputation! They can be as obedient and sweet as any other dog. 🥰
Good dog training with patience is essential to ensure the zen of your adorable Chihuahua.
🙌 Remember these five essential points:
1) Watch for bad behaviors and reward obedience.
2) Teach your dog that you are their protector.
3) Socialize your Chihuahua from a young age.
4) Be attentive to times when they may be sick or in pain.
5) Always treat your companion with respect, even when they are playing with their favorite toy.
Walking your dog often with the implementation of healthy habits and routines will make your beloved Chihuahua’s life more pleasant!
