What Causes Chihuahuas Aggression?

What Causes Chihuahuas Aggression?

This is due to a phenomenon known as “small dog syndrome.” Smaller breeds, such as Chihuahuas, are sometimes noisy, growl a lot, and are even aggressive enough to bite.

Chihuahuas have a sassy and headstrong personality, and despite their size, they don’t willingly back down in a fight. But this is not to say that small breeds are not doomed to be aggressive.

Your Chihuahua’s aggressive behavior may not be in its nature, but rather a result of the way it responds to it. This breed tends to be more reactive and perceive the environment as more threatening than it really is.

Another important factor is the relationship that is established between the family and the dog. Generally, owners treat large dogs with different rules and expectations than small dogs.

Depending on how you train your Chihuahuas, it could display different behaviors. On the one hand, he can be affectionate, playful, and whimsical

. On the other hand, it can become a nervous dog and show aggressiveness or dominance when it is very spoiled, a mistake that we easily make because we get carried away by its “fragility.”

But this pet can become the ideal companion if we learn more about its character and educate it correctly from a young age.

On the other hand, if we pamper it a lot and do not apply the necessary rules, we will be creating a disobedient and capricious dog, and consequently aggressive.

How Can I Correct Mean and Angry Behavior in Chihuahuas?

Impose rules

One of the causes of aggressive Chihuahua is the dominant behavior. If your Chihuahua is behaving aggressively, it may believe that it is in charge.

Set rules for your Chihuahua to assert its position as a pack leader (remember that you don’t need to be mean or rude to be the alpha). Think of the rules that suit your needs. For example

  • Do not allow your Chihuahua to sleep in your bed.
  • Require that it stay out of the kitchen while cooking.
  • Ask your Chihuahua to sit and wait while you prepare its food or open the back door.

Don’t reinforce the behavior

Don't reinforce the behavior

If your Chihuahua growls and barks at strangers entering your home, don’t pick it up and pet it. Don’t let it sit on your lap while it grows at your visitors.

It should have special privileges only if he is calm and friendly. When your Chihuahua is aggressive, take it out of the room. Put it in its box until your visitors leave or until it has calmed down. Put it on the ground if it insists on growling

Reward appropriate behavior

Every time you have visitors or your Chihuahua is exposed to other situations that trigger its aggression, reward it if it remains calm and friendly.

Try to interrupt its aggression with the words “no” or “stop it.” If it stops growling enough to turn toward you, reward it.

Establish longer and longer periods of calm before rewarding your dog. Allow it to be in the room or on your lap while it is quiet. When you reward your Chihuahua for being friendly rather than aggressive, you reinforce the behavior you want it to display.

Don’t forget basic obedience

Don't forget basic obedience

Due to the small size of a Chihuahua, many think that obedience training is not necessary. This is a severe error. Teaching a chihuahua’s basic obedience commands will help you maintain your position as a pack leader and give you a way to control your Chihuahua’s behavior.

You should teach your Chihuahua the basic commands like sit, lower, come, and stay. Use positive reinforcement to train your Chihuahua, rewarding it for obeying each command correctly. Chihuahuas are smart and fast learners, do not punish your Chihuahua, or it may make its aggression worse.


It is essential to socialize your Chihuahua with other dogs, animals, adults, and children. You should start socializing when your pet is a puppy.

If you don’t socialize with your Chihuahua, it may panic and act aggressively when hit encounters unfamiliar people or animals. So, start socializing your dog as soon as you get her home.

Take your Chihuahua to the parks and introduce them to as many people and animals as possible. Now that you know how to avoid aggressive behavior in your Chihuahua, nothing better than a quiet time with your best friend!
