How to Train Your Chihuahua not to Bite

The chihuahua family is generally associated with an instinctual characteristic of biting as a means of defense strategy. Their specialized canine teeth are there for killing their prey for food and defending themselves from predators. They have inherited these wild characteristics even though they have been domesticated. A chihuahua’s bite can be a danger to humans. Therefore there is a need on how to train a chihuahua not to bite. The training involves understanding the reasons that trigger them to bite.

Dangers of chihuahua Bites

Many people may ignore the fact that chihuahuas may cause immense dangers to their family and friends. Despite the fact that chihuahuas are nice all the time, their bite may cause extreme dangers compared to larger dogs. The most dangerous instance is when the chihuahua is not vaccinated against possible diseases like rabies. Because These diseases can be transmitted to humans. Unsterilized open wounds caused by chihuahua bites are at risk of getting germs and fungal or bacterial infections that will worsen the situation. In addition, the owners of chihuahuas may have some troubles with the law and some obligations to pay bills and fines to their dog’s victim.

Why chihuahua Bite?

Even the friendliest dogs exhibit biting behavior when they face extreme situations. Chihuahua owners must familiarize themselves with the trigger factors that may make their pets to be aggressive and dangerous.

1. Pain-Caused Aggression

Chihuahuas do react to danger by being aggressive when inflicted with the pain they do react by lashing out and biting the person who is nearest. The chihuahua does not lash at the person who inflicted the pain but just anyone around as a way of seeking comfort from their painful experience. The painful experience is the result of an injury or a medical condition and physical pain inflictions like beating.

There are a lot of health conditions that can affect this breed like patellar luxation. So when a chihuahua is suffering from one of those health issues he may react by showing aggressive behavior, especially when someone touches the dog in the area where the pain is located. For this reason, all the family members must hold the dog carefully when he suffers from a health issue or an injury. 

2. Teething

Teething is painful to experience in dogs. The teething period is normally 5 weeks of age. Whereby the teeth start to grow to help them transition from soft to harder foods. As a way of seeking comfort in this painful experience, the Dog normally bites on anything they find. The dog will bite on any material around like shoes, mats, and utensils. And worse they may bite on babies or owners’ feet.

The puppy won’t stop biting until he has all 28 baby teeth. However, because of his young age and weak jaw, the puppy won’t bring any damage. Even so, you should teach him that biting is intolerable.

Here are some tips to help you control your dog’s biting during the teething period:

  • Try to teach your puppy bite inhibition 
  • Give him some frozen food such as chicken or beef broth 
  • Provide proper toys dedicated to puppies who are in a teething stage like kong toys.

3. Reaction to Past Neglect

Have you ever been neglected by your parents? The situation triggers mixed emotions of anxiety, fear, and hate. The same happens to a neglected dog. The neglect and abuse from the past will trigger them to bite as a means of defense.

When you adopt an adult chihuahua from a shelter, try to have a full idea about his past, to expect and correct any unwanted behavior.

Dealing with a fearful or shy chihuahua is not easy, a dog who experienced negative experiences such as social isolation, verbal punishment, etc will take a very long time to trust humans again. However, it depends on the dog’s character because there are some chihuahuas who will recover quickly, and some who will keep their negative emotions for a long time. Patience, love, and affection are required in order to help your dog overcome these emotional scars.

Because of their small size, chihuahuas tend to protect themselves to avoid pain. So when a chihuahua displays aggressive behavior it doesn’t necessarily mean that the dog is suffering from something.

Some diseases may trigger aggressiveness in chihuahuas such as hypothyroidism and Lyme disease. When there is not enough production of the Thyroid hormones, a dog may display aggressive behavior.

Lyme disease is a disease responsible for aggressive behavior in chihuahuas. The main cause of this behavior is the bite of an infected tick. There are some symptoms of this disease such as swollen joints, swollen lymph nodes, loss of appetite, etc.

In order to verify if your dog suffers from Hypothyroidism, a simple blood test can reveal if the dog is suffering from this disease. The vet may prescribe Thyroid hormone supplements such as Levothyroxine to treat this disease.

Concerning Lyme disease, the most effective way to prevent this disease from occurring in the traditional tick prevention methods. However, there is also a vaccine available for this disease.

Way of Self-Protection

The chihuahua family is territorial in nature, they live defending their boundaries. And they will thus react to anything that seems to violate their territories. For instance, if one tries to temper their sleeping or feeding zones, the chihuahua will react aggressively by biting the intruder. Holding the dog in a suggestively harmful position, for example, grasping their necks, triggers an instinct of danger to them and thus reacts aggressively.

To stop a chihuahua from biting caused by territorial aggression, teach him that you are the leader of the household and he can trust you. In the case of a stranger show the dog that is ok using the tone of your voice and non-verbal cues.

Maternal Aggression

Female chihuahuas could be aggressive after 2-3 weeks after delivery. This unwanted behavior is the result of changes in the body hormones of the dog. As there is an increase in the production of oxytocin and prolactin and a decrease in the production of progesterone.

The oxytocin is called also the “love hormone”,  emitted by the hypothalamus, a brain part responsible for nurturing, attachment, and maternal bonding. This hormone also encourages contractions during labor, in order to help the fetus to move easily through the birth canal.

When a chihuahua female is about to give birth, there is a decrease in the production of progesterone hormone. Which results in an increase in the production of prolactin hormone. This latter has so many roles in the body of a female dog, such as stimulation of milk production, nesting, and maternal instinct. Some experts believe also that prolactin is responsible for some of the behaviors of a chihuahua female dog during pseudopregnancy. These powerful chemical alterations occurring throughout her body can make a chihuahua female more aggressive during pregnancy.

During the pregnancy or shortly after the delivery, do not try to correct the dog’s aggressive behavior, instead, you have to stay away from your dog until her hormones go back to normal. If you want to check the puppies wait until she moves for food, water, or bathroom. Don’t worry her aggressive behavior will vanish after 3 to weeks.

Because of their size chihuahuas are always afraid of other people and animals. A lot of chihuahuas suffer from what we call “little dog syndrome”. It is normal for a chihuahua to become fearful of unfamiliar people and situations. 

As a chihuahua owner, you should understand your chihuahua’s behavior and temperament very well. So if your chihuahua is not familiar with strangers, don’t let them touch or pet her as it is uncommon for people to stop and pet dogs in the streets.

How To Train a chihuahua not to bite

Before starting any training you have to reveal the real reason behind this behavior. However, the following tips may help you reduce many instances of biting.

Don’t Punish your chihuahua for Growling

A lot of chihuahua owners punish their chihuahuas for growling. This is a wrong idea because growling is considered a key warning sign that comes before biting. When a chihuahua learns that growling is not accepted, she may bite directly when she is forced to. You should put in mind that growling is a sign you can use to prevent biting from your dog.

In fact, some chihuahuas can’t bear children, so when a chihuahua starts growling in front of a kid, you can ask the kid to back away from the dog to avoid damage caused by the dog’s biting.

Growling is always associated with a situation. For this reason, you can use it to reveal the cause of the dog’s aggressive behavior. For instance, when a chihuahua growls when a child approaches him, maybe your dog needs the be socialized, or if your dog growls when you pick up him, perhaps he has a painful injury or a health issue, etc.


According to some experts, spaying or neutering may reduce chihuahuas’ aggression. Because neutering decreases testosterone levels, as a result, all the unwanted behaviors related to this hormone may vanish, such as territorial marking, running away, hyperactivity and aggression.

On the other side, spaying, a female chihuahua deletes her heat cycle, as a result, the behaviors connected with going into heat are eliminated too.

Long-ago people believe that neutering dogs before puberty is a must, to stop a dog from developing bad behaviors. However, according to American Veterinary Medical Association (AMVA), neutering dogs after puberty is ok and functional too.
