I am a chihuahua owner of two purebred chihuahuas, and we are all just getting along. They sleep with me, play with me, give lots of kisses, and like to say hi to everyone we meet (whether they want to or not). And yet there’s this common conception that chihuahuas are mean and snappy. Do chihuahuas ever bite? Yes. But it’s not some crazy statistic, and they’re not just out to get you — so let’s explore why chihuahuas are mean and how to tame them.

About Chihuahuas

Chihuahuas are a small breed of dog that originated in Mexico. They are one of the oldest recognized dog breeds, but they were not recognized by the American Kennel Club until 1904. The Chihuahua is known for its small size and its long coat, which can be either smooth or long-haired. They have large ears and eyes, and they typically weigh between 2 and 6 pounds.


Chihuahuas are energetic dogs that need plenty of exercise to stay healthy and happy. They can live indoors or outdoors, though they prefer to be inside with their owners. They do not require a lot of grooming, but they do shed often. Chihuahuas are good watchdogs because they bark when strangers approach or try to enter your home. They also tend to be great companions for children due to their small size and playful nature.

Why are Chihuahuas so mean?

I can attest that not all chihuahuas are mean. However, a common perception is that chihuahuas tend to be aggressive or snappy. This can be attributed to a number of reasons, including genetics, socialization, and behavior training.

Firstly, chihuahuas have a reputation for being a “yappy” breed. They are known to bark incessantly at strangers or other dogs, which can be mistaken for aggression. This behavior is partly due to their genetics, as chihuahuas were originally bred as watchdogs. However, with proper training and socialization, a chihuahua can learn to control their barking and become a well-behaved companion.


Another factor that can contribute to a chihuahua’s perceived aggression is their size. Chihuahuas are one of the smallest dog breeds, which can make them feel vulnerable or threatened in certain situations. This can lead to defensive behavior like growling, snapping, or biting. It’s important for chihuahua owners to be aware of their dog’s body language and to avoid putting them in situations that could trigger this type of behavior.

Finally, like any dog, a chihuahua’s behavior is largely influenced by their training and socialization. If a chihuahua is not properly trained or socialized, they may display aggressive or dominant behavior. It’s essential for chihuahua owners to establish themselves as the pack leader and to provide their dogs with consistent, positive reinforcement training.

Why are Chihuahuas so aggressive to other dogs?

Chihuahuas are aggressive to other dogs because they are territorial, and they have to protect their space. They also have a very high prey drive, which means they are more likely to chase after smaller animals and get into fights with other dogs or cats.

Chihuahuas are also very sensitive and easily frightened, so if you have a Chihuahua that doesn’t seem to like other dogs, it’s probably because they have been scared by them in the past.

How to introduce Chihuahuas to other dogs

Introducing your Chihuahua to other dogs can be a delicate process, but if done correctly, it can help your dog learn to socialize and interact with other canines in a positive way. Here are some steps to follow when introducing your Chihuahua to other dogs:

Choose the right time and place.

When introducing your Chihuahua to other dogs, it’s important to choose a neutral location where neither dog feels threatened or territorial. Avoid introducing dogs in areas such as your home or backyard, as these are places where your Chihuahua may feel protective. A neutral location like a park or a friend’s backyard is ideal.

Use a leash and muzzle.

For safety reasons, it is best to keep your Chihuahua on a leash and use a muzzle when introducing them to other dogs. This will prevent any aggressive behavior and keep both dogs safe.

Start with a calm dog.

It’s essential to introduce your Chihuahua to a calm, well-behaved dog. This will help your Chihuahua feel more at ease and less threatened. Avoid introducing them to overly energetic or aggressive dogs.

Allow dogs to sniff each other.

When both dogs seem calm and relaxed, allow them to sniff each other while on a short leash. This will help them become familiar with each other’s scent and body language.

Monitor body language

Keep a close eye on both dogs’ body language during the introduction. Signs of aggression or discomfort, such as growling or raised hackles, should be addressed immediately. If either dog seems uncomfortable or aggressive, separate them and try again at a later time.

Gradually increase interaction

If both dogs seem calm and relaxed, gradually increase their interaction. Allow them to play and interact while still on a leash, and reward good behavior with treats and praise.

End on a positive note

When the interaction is over, end on a positive note. Offer both dogs treats and praise for their good behavior.

Introducing your Chihuahua to other dogs can take time and patience, but with the right approach, it can help your dog learn to socialize and interact with other canines in a positive way. Always remember to prioritize your dog’s safety and comfort during the introduction process.

Signs of an aggressive Chihuahua

While not all chihuahuas display aggressive behavior, some can become aggressive towards humans or other animals. Here are some signs to look out for:

  • Growling: If your Chihuahua is growling, it may be a sign of aggression. This can occur when your dog is feeling threatened or territorial and may be followed by other aggressive behaviors.
  • Snarling: Snarling is a more serious sign of aggression in chihuahuas. This occurs when your dog is showing its teeth and making a growling noise. This is a clear sign that your dog is feeling threatened or aggressive.
  • Biting: If your Chihuahua bites, this is a clear sign of aggressive behavior. While chihuahuas are small, their bites can still cause serious harm. It’s important to address this behavior immediately to prevent further aggression.
  • Lunging: A chihuahua that is lunging towards someone or something is displaying aggressive behavior. This is usually accompanied by growling or snarling and can be a sign that your dog feels threatened or territorial.
  • Stiff body language: If your Chihuahua’s body language is stiff and tense, this can be a sign of aggression. This is often accompanied by raised hackles and a lowered head.
  • Excessive barking: While chihuahuas are known for their yappy barks, excessive barking can signify aggression. If your Chihuahua is barking excessively at someone or something, it may be a sign that they are feeling threatened or aggressive.

What to do if a Chihuahua bites you?

Chihuahuas are small dogs with large teeth, and that can mean a lot of damage during a bite.

If your Chihuahua has bitten you, here’s what you should do:

  • First, see if there are any puncture wounds or bleeding. If there are, call your doctor right away (even if it’s just to make sure).
  • Next, look for signs of infection—redness and swelling around the wound or in other areas of skin that may have been exposed. Again, if this happens, call your doctor immediately.
  • If everything looks good at this point (no punctures or bleeding), make sure to wash the area thoroughly with soap and water. Then apply an antibiotic ointment before covering it in gauze bandage or something similar until it heals completely (this will help reduce the risk of infection).
  • Finally—and most importantly—keep an eye on that bite! If you notice any redness or swelling develop around it after a few hours post-bite, contact your doctor.

How To Tame an Aggressive Chihuahua?

Taming an aggressive chihuahua can be challenging and time-consuming, but it is possible with patience and commitment. Here are some steps to follow when trying to tame an aggressive chihuahua:

Identify the cause of aggression.

The first step in taming an aggressive chihuahua is to identify the cause of their aggression. It could be due to fear, territorial behavior, or a lack of socialization. Understanding the cause of your dog’s aggression can help you address the issue effectively.

Consult with a professional

It’s important to consult with a professional dog trainer or behaviorist if your Chihuahua is displaying aggressive behavior. A professional can help you develop a personalized training plan and provide guidance on how to safely and effectively train your dog.

Establish trust

To tame an aggressive chihuahua, you need to establish trust with your dog. This can be done by spending quality time with your dog, offering treats and praise for good behavior, and avoiding punishment or physical reprimands.


Socializing your Chihuahua is vital to help them learn appropriate behavior around other dogs and people. Start by introducing your dog to calm and well-behaved dogs in a controlled setting, and reward good behavior with treats and praise.


Training is essential to taming an aggressive chihuahua. Start with basic obedience training, such as sit, stay, and come, and gradually work up to more advanced training. Use positive reinforcement techniques such as treats and praise to motivate your dog and encourage good behavior.


Consistency is key when taming an aggressive chihuahua. Stick to a regular training schedule and be patient with your dog. It may take time for your dog to learn new behaviors and habits, but you can help them overcome their aggression with consistency and patience.

Seek professional help if necessary.

If your Chihuahua’s aggression persists or worsens, seek professional help from a veterinarian or behaviorist. They can help you identify any underlying medical or behavioral issues and provide additional guidance on how to train your dog.


Do Chihuahuas have anger issues?

Yes, Chihuahuas have anger issues.
Chihuahuas are very territorial and protective of their owners, so they may become aggressive when they see another dog or person in their home. They can also be aggressive toward other animals, such as cats and rabbits.

Are Chihuahuas Naturally Mean?

Chihuahuas aren’t naturally mean, but they can be. Chihuahua owners should know that the breed can be aggressive and territorial, especially in their homes or yards.


While chihuahuas may have a reputation for being mean or aggressive, this is not necessarily true for all dogs of this breed. With proper training, socialization, and care, a chihuahua can be a loving and well-behaved companion. As a chihuahua owner, it’s essential to be patient, consistent, and understanding in order to help your dog reach their full potential.
