Are Chihuahuas more aggressive than Pit bulls? (myth or reality)

In this article, we will give a final answer to this question: Are Chihuahuas more aggressive than pit bulls? Keep reading to learn more about the behavior of a chihuahua, and if we should be more prepared near a Chihuahua or a Pitbull…

Are Chihuahuas more aggressive than Pit bulls?

A recent study has revealed that Chihuahuas are true, more aggressive than Pit bulls.  Small dogs tend to be more aggressive than large dogs, that’s a fact. Blame it on an inferiority complex linked to their small size? It remains a mystery. 

Nevertheless, the Dognition site, which collects data on dog behavior, wanted to look at the aggressiveness of different breeds of dogs in all kinds of situations. And the least we can say is that the results are stunning!

By collecting data from different dogs in different situations (meeting a new or known person, a new or known dog, a larger or smaller dog, a child, etc.), the site made a surprising discovery, to say the least, Chihuahuas almost always come first in terms of aggression, no matter what situation they are faced with. And strangely enough, they are even more aggressive when they meet large dogs that they have never met before.

Not-so-mean Pitbulls

While the Pitbull is considered one of the most aggressive dog breeds around, the study, based on responses from 4,000 dog owners, reveals that in fact, it is not. The Pitbull is in fact ranked among the least aggressive dogs, like the Cavalier King Charles, the Pug, or the Collie. Indeed, the reactions of dogs of this breed to all the situations cited by the study could not be more peaceful.

These results show that prejudices about dogs considered “dangerous” die hard, but they are completely unfounded! And for good reason, even if dogs like the Pitbulls have a history of warriors, they are not born aggressive. Of course, their aggressive instincts can be aroused more quickly than in other dogs. But it all depends above all on the education they receive and the environment in which they operate.

Thus, most dogs become aggressive when mistreated from an early age or trained by violence. If a Pitbull is mean, it is not him or even his breed to blame. But indeed his owner.

It is true that there are still Chihuahuas with aggressive behaviors … and behaviors likely to bite people, but is it the aggressiveness coming from the genes of the breed, or are there other factors? Personally, I think that if a chihuahua is aggressive, the cause goes to the owners!

How to address the aggressive behavior of a Chihuahua? 

There are things you can do to make sure your Chi isn’t aggressive.

  • Socialize your chihuahua, make him meet as many people as possible,… Take your chihuahua with you whenever you can.
  • Do not physically punish your Chi. Hitting it can cause aggressive behavior
  • Don’t let your chihuahua decide. If you tell him no, and he answers you (well refuses and shows those fangs), you have to get tough.
  • An isolated Chihuahua can become a fearful Chi. Fear can become the basis of aggression.

Reasons why Chihuahuas are aggressive

Before looking for the solution, here are some reasons why your Chihuahua may act aggressively:


Socializing with other dogs, animals, adults, and children is extremely important for your Chi. It is important to start as soon as your Chihuahua is a puppy. This is because if your Chihuahua does not socialize, he can become frightened and act aggressively when he meets unfamiliar people or animals. 

So, start getting your Chihuahua used to socialize as soon as you bring them home. Take your Chihuahua to the parks and present it to as many people and animals as possible.

Bad treatment:

Basically, never hurt your Chihuahua. You can be firm but never use physical punishment on your Chihuahua. because if you do this your Chihuahua will become scared and it can make him aggressive. 

So, instead of scaring your Chihuahua, you should instead show them that you are the leader (the pack leader) of your household. Rather, be calm and assertive with your Chi instead of scaring it. This will keep your Chihuahua calm and he will be less likely to become aggressive.

How to deal with aggressive Chihuahuas

There are a number of methods you can use if your Chihuahua is aggressive.


Normally, you need to take control and set limits for your Chihuahua. In fact, you should allow your Chihuahua to be only in those parts of your house where it is allowed. If he is not allowed in the bedroom, never let him in. Having a fixed time for food will also help fight aggression during meal times. 

Thus, by having control and limits, your Chihuahua will feel secure and will be less likely to become aggressive.

Chihuahuas aggressive towards other animals:

If your Chihuahua becomes aggressive towards another animal, it is important to stay calm. If it’s safe, separate the animals. Also, don’t overreact or show affection for your Chihuahua after the incident. Instead, take your Chihuahua away from where the aggression happened and use assertive commands such as “No” to let him know his behavior was wrong. But remember to never use physical punishment.

Chihuahuas who are aggressive towards people:

It is not a good sign if your Chihuahua is aggressive towards people. It is true that he may be small, but his bite will hurt. Certainly, it can be dangerous for small children and adults too.

Besides, the so-called “natural” aggressiveness of category dogs, let’s talk about it! You know this law which catalogs dogs who have asked for nothing and who are simply subjected to the non-benevolence and extremism of men. The so-called “dangerous” category dogs are the very example of the (harmful) influence of humans.

3 major tips to avoid dog aggressiveness

Know how to read and understand the signals emitted by the dog.

Indeed, naturally, a dog will seek to avoid conflict rather than provoke it. Thus, it is important to know how to decode all the signals sent by the dog, in particular to avoid attacks on humans. 

Regarding interactions and potential aggression between dogs, this is where the importance of good socialization comes in because a dog will have communicated from an early age with other dogs.  

Some examples of signals that can alert you to a dog’s illness: he will yawn, look away and look away, lick his nose (be careful, if the licks are repeated and rapid, this translates to an illness such as aggression is not far away).

Then there are of course the warning signs: the bark, the growl, the “smile” or the quick nose licking, and repeated as mentioned above.

Offer quality socialization. We have partially mentioned it previously but here I remind you of the importance of good socialization to allow the dog to experience different situations as if they were ultimately non-events. Always assume that a dog will be afraid of what he doesn’t know. And we saw that fear of aggression was certainly the worst of all.

Thus, allow your dog to meet as many dogs as possible (being almost certain that it will go well, of course, the encounters must above all be controlled), but also a multitude of diverse situations and environments: the city, the forest, the market, the car, importable noises, different people, atypical objects, etc.

Have a relationship of trust and mutual respect with your dog. I am thinking in particular of dogs who attack because they do not feel safe in such and such a situation. Know that your dog must consider you as his referent, his “guardian”, you must therefore play this role! 

So, have a consistent attitude, well-defined rules of daily life, and above all: have confidence in yourself and your dog! If you are already completely sure that everything will go well, this will not necessarily solve all the problems, for all the situations, but believe me, the process will be different! Quite simply because you will impose a framework and a reassuring attitude on your dog.


Chihuahuas are known to be sometimes aggressive, as they have more self-confidence and face situations more directly compared to other breeds; thus, these little dogs tend to be reactive because their perception of the world is more threatening.

It is very important to socialize your Chihuahua around other dogs, animals, adults, and children. You should start socializing when your pet is a puppy. If you don’t socialize with your Chihuahua, she may get scared and act aggressively when she encounters unfamiliar people or animals. 

One of the causes of aggression in dogs is the dominant behavior. If your chihuahua is behaving aggressively, he may think he is the dominant one. Establish rules so that your chihuahua understands your position as pack leader. (Remember, you don’t have to be mean or tough to be the alpha.)
