This is a question most Chihuahua owners ask. It is worth knowing that every dog can be mean. But are Chihuahuas mean dogs?

Meanness is not a particular dog’s trait. Some Chihuahuas can be friendly, calm, cheerful, and even shy, while others can be stubborn, nasty, and aggressive.

Below are some factors that can influence this unusually aggressive behavior in your dog.

The Genetic Temperament of Its parents and ancestors

Some Chihuahuas inherit their bad behaviors from their families.

That’s why it is advised to meet your Chihuahua’s original parents to ensure it does not have inherited genes for a bad attitude.

Size (Small Dog Syndrome)

Chihuahuas are really small dogs, and when they come in contact with bigger ones, it can be intimidating.

When dogs feel intimidated, they are likely to react in two ways: fight or escape.

Chihuahuas are not naturally mean dogs; they start to act defensive and choose to put up a fight when they feel intimidated.

Bad Training

when you excuse some bad attitudes your Chihuahua start exhibiting, you’re only breeding stereotypes.

It is not cute behavior to act nasty and mean. Train your dog early, so it doesn’t become so aggressive later on.

Poor Socialization

When you choose not to introduce your Chihuahua to other dogs, it won’t know how to behave around them because it’ll continue to feel intimidated and behave so unruly.

Preventing your Chihuahua from having a social experience can backfire in the long run.

Underlying Health Condition

Your Chihuahua can be aggressive because of a health issue you haven’t detected yet.

Your doggie won’t tell you when it’s hurting, so it is advisable to be on the lookout for signs that will show if your dog is healthy or not.

Post-Traumatic Stress Disorder (PTSD)

The aggressive behavior of your pet can be a result of PTSD. It reacts to everything violently as a defensive mechanism to protect itself from its past bad experiences.

It gets triggered once it perceives just the tiniest threat.

Territorial Nature

Chihuahuas, with their dominant personalities, are known to be inherently territorial dogs, and they can’t tolerate others in their own space.

If they feel you’re a threat to them, they won’t keep from intimidating you.

Anxiety

Chihuahuas are extremely sensitive dogs, and they get anxious about a lot of things which can lead to them acting negatively toward people around them.

Chihuahuas have a “not-so” great reputation for being mean, and there’s an ounce of truth in this.

“Change is constant and begins with you!” Though this nasty Chihuahua temperament might be inherited, there are known ways for dog owners to control it.

Proper Training

Your Chihuahua can come from a friendly home and still be aggressive to other dogs and humans.

As a Chi parent, you should equip your dog with adequate training because there is nothing cute about being so mean. Don’t overindulge it to behave nastily.

There are training classes also for dog owners who find it hard to train their Chihuahuas.

Encourage Early Socialization

Your Chihuahua socializing with other dogs is of great importance and should be encouraged.

Perhaps, interacting with other dogs can make them more friendly, sweet, and less aggressive.

It is advisable to start quite early to enable your dog to behave properly around people and other dogs.

Introduce Spaying or Neutering

Spaying can help curb nastiness in Chihuahuas, though not a long-lasting solution.

It will ensure the hormones that make them unfriendly and overly aggressive are no longer produced and control the meanness to keep your dog calm.

Detox Your Dog’s Mind of all its Bad Experiences

Some of these dogs have had nasty experiences, and they put up a bad attitude as a way to defend themselves from their past.

They suffer from PTSD and believe everyone is out to hurt them, so they try to act mean around others. You can correct the bad temperament caused by a horrible past by showing them enough love and care.

Make your dog feel happy and comfortable and show it that it doesn’t need to be frightened and act horribly.

Help it heal away from all of its bad experiences and troubled past.

Introduce Regular Exercising

Exercising is a wonderful way to control your Chihuahua’s snippy behavior. Half an hour of exercise can play a huge role in reducing your dogs’ meanness.

It has other benefits like making it less prone to diseases, keeping them fit, and killing boredom.

Schedule Regular Trips to the Veterinary Clinic

It is important that you take your Chihuahua on regular visits to the vet in cases where it becomes aggressive due to an underlying medical condition.
