Is a Biting Chihuahua Really That Bad?

The Centers for Disease Control and Prevention (CDC) estimates that more than Each year, 4.7 million dog bites occur in the United States. 800,000 of whom want medical care. However, many owners ignore their Chihuahua’s biting due to their small stature. After all, a 5-pound Chihuahua can only do so much damage.

A bite from a Chihuahua can nevertheless leave a painful wound that is vulnerable to infection, even if it won’t do as much harm as a bite from a larger dog like a pit bull or boxer. It’s a common misconception that a dog’s mouth is cleaner than a human’s, however this is untrue. A dog’s saliva may include one or more microorganisms that cause disease, including as Staphylococcus, Streptococcus, Pasteurella multocida, and Pasteurella canis and Canimorsus the capnocytophage. These types of microorganisms can enter the bite wound after a Chihuahua bite and lead to an infection.

The owner is also financially liable for the dog’s biting. A visitor to your home who is bitten by your Chihuahua may file a claim against you to recover damages for their suffering and medical costs. According to State Farm and the Insurance Information Institute (III), Dog bites accounted for about one-third of all homeowner’s insurance payouts in 2014 and 2015. .

In addition, children between the ages of 5 and 9 are typically the ones who get bit by dogs. They are an easy target for attacks because of their small stature, irregular movements, and inability to tell a dog’s disposition apart. Children and Chihuahuas can live together safely, but only after teaching them both the limits of proper conduct.

Why Chihuahuas Bite

Chihuahuas have inherited some behavioral tendencies from their predecessors, such as biting. When pushed to the limit, even the most gentle Chihuahua can bite. Owners need to be aware of some of the causes of Chihuahua bites in order to stop this unpleasant behavior.


At 3 to 5 weeks of age, a Chihuahua puppy’s baby teeth (milk teeth) will erupt through his gums, enabling the pup to switch from mother’s milk to dry food. Puppies will bite and chew on almost anything they can get their hands on, including toys, socks, shoes, carpet, rugs, and even your hand, to ease the discomfort caused by this developmental process.

The 28 baby teeth will all eventually sprout before this activity stops. When his adult teeth develop, which typically takes place between 3 and 4 months of age, your Chihuahua’s gnawing and biting habits may resume.

A puppy’s bite won’t do much harm because of his early age, and he doesn’t mean to hurt anyone. However, it’s crucial to start teaching your Chihuahua that biting is unacceptable as soon as possible.

To prevent your Chihuahua from biting while it is teething, use the following advice:

  • Allow your Chihuahua to bite your fingers, but don’t encourage it.
  • When your Chihuahua bites too hard, yank your hand away and remark, “Ouch! That hurts!” to teach biting inhibition. This is the most crucial action you can take. (We go into further detail below.)
  • Low-sodium chicken or beef broth should be added to ice cube trays before freezing. Give your teething Chihuahua the frozen treat after it has cooled.
  • An fantastic and nourishing treat for a teething Chihuahua are chilled carrots.
  • By giving your Chihuahua the right toys, you can prevent them from chewing on things like shoes and carpet. Because they can resist numerous hours of gnawing, rope toys are excellent. The toughest dog toys available are Kong toys, which are ideal for a teething Chihuahua. For further gum pain treatment, you may even fill them with water and freeze it.
  • Avoid soft toys since they are easily torn apart and provide little to no relief for sore gums.

Maternal Violence

During the first two to three weeks after giving birth, female Chihuahuas are more inclined to bite. This behavior, known as maternal anger, is brought on by significant physiological changes in her body, including elevated levels of the hormones oxytocin and prolactin and lower levels of progesterone.

The brain’s hypothalamus releases oxytocin, also referred to as the “love hormone,” which is linked to maternal bonding, nurturing, and attachment. It helps the fetus pass through the birth canal by causing contractions to be stimulated during labor.

When a female Chihuahua is about to give birth, levels of the soothing hormone progesterone drop, which causes prolactin output to rise. Prolactin is linked to nesting and mother instinct in addition to promoting milk production. Additionally, according to veterinary professionals, prolactin is mostly to blame for the actions displayed by female dogs during pseudopregnancy. A female Chihuahua that goes through these hormonal changes during or soon after pregnancy may become more aggressive.

Keep your distance from a female Chihuahua until her hormones return to normal rather than attempting to correct her maternal hostility. Wait until she exits her nesting location for food or water if you need to examine or weigh her pups. After having birth, her hostility should progressively lessen with time, returning to normal within 3 to 4 weeks.

Pain-Stimulated Violence

Chihuahuas have the innate desire to defend themselves from harm. No matter who inflicted the suffering, a Chihuahua may snap and bite the person who is closest to him when he feels agony. He has no idea who or what caused the harm, but his inherent drive to fight or flee urges him to attack the closest human or animal.

In a study of 13 dogs, pain-induced hostility was seen in every dog, according to researchers at Autonomous University of Barcelona. ” In instances where an effort is made to control them, dogs who had never been combative before the onset of pain started acting in this way. “Tomàs Camps, the lead researcher, explained. This investigation was released in the Clinical Applications and Research in Journal of Veterinary Behavior .

Your Chihuahua may act aggressively when touched in the knee that is affected if he has patellar luxation, a problem that is frequent in this breed. When handling a Chihuahua who has painful medical illnesses or injuries, owners and family members should exercise caution to prevent getting bit.

Chihuahuas can display pain-induced aggression without necessarily having an injury or a medical issue. Due to their small stature and increased sensitivity to pain, toy breeds are particularly prone to pain-induced aggressiveness. A youngster (or anyone) who tugs, pushes, squeezes, or pressurizes your Chihuahua too hard risk getting bit.

These symptoms could indicate that your Chihuahua is in pain:

  • aggressive attitude
  • rounded ears
  • reduced appetite
  • Uninterested in participating
  • refusal to accept rewards
  • When touched, yelping, whining, or growling (reactions such as these typically occur when a specific spot is touched)
  • Jumping and stair climbing are difficult.
  • thick clothing
  • a lot of paw licking
  • trouble sleeping

Make an appointment with your veterinarian as soon as possible if you think your dog is in discomfort. Following an examination, your veterinarian can assist in determining the source of the discomfort and provide guidance on available treatments and painkiller options.

Past Abuse

Behavioral and psychological traits of canine abuse victims, a study that was published in the journal Applied Animal Welfare Science Journal According to the (JAAWS), dogs with a history of abuse were more likely to act aggressively toward strange humans and strange pets.

If you adopted a Chihuahua from a shelter or rescue, it’s possible that his biting was caused by cruelty on the part of a previous owner. Although many abuse incidents go unreported, you might check with the agency where you adopted your Chihuahua to determine if there has ever been a history of abuse.

Abuse takes many various forms, including physical mistreatment, social exclusion, verbal reprimands, chaining up the puppy, and early separation from its mother. After experiencing such violence, some Chihuahuas bounce back quickly, but others suffer emotional scars that endure a lifetime and pave the way for aggressive behavior.

It takes time and effort to rehabilitate a Chihuahua who has been subjected to cruelty. But with time, love, devotion, and loads of attention, you may assist your Chihuahua in overcoming these unfavorable emotions.



If a chihuahua feels threatened, he is more likely to bite another dog or human. Because dogs are afraid of strange people and surroundings, veterinarians are frequently the target of such hostility. Your Chihuahua could snarl and nip during the examination the first time you bring him to a new vet. The vet isn’t going to hurt your dog, but that doesn’t mean they won’t be viewed as a potential threat.

Owners should warn visitors not to pet or otherwise interact with their Chihuahua because strangers are frequently the targets of fear bites. In the park, it’s not unusual for total strangers to pause and pet pets. They put themselves at risk of getting bitten by doing this. If you are walking your Chihuahua in a park or other public space, kindly refuse any requests to pet your dog, unless your Chihuahua knows the person.

Socialization is essential for preventing fear-induced biting. .


Chihuahuas have a strong drive to defend anything they perceive to be theirs, including beds, food, treats, water, toys, and people. A Chihuahua is more likely to bite another person or animal if that person or animal intrudes upon their property. This behavior is known as territorial aggression. It’s not meant to hurt the person; rather, it’s meant to drive them away.

The act of a postal worker delivering mail to a residence only to be pursued and possibly bit by the homeowner’s dog is a prime example of territorial aggressiveness. The United States Postal Service (USPS) reported that 6,549 of its employees experienced dog attacks in 2015. The mail worker is seen by the dog as intruding on HIS His natural reaction is to chase the postal worker away because he is in his domain.

Teaching your Chihuahua that it’s not okay to bite starts the process of preventing territorial aggressive bites. YOUR real estate and that YOU will safeguard it. If he reacts violently when a stranger knocks on the door, you may teach him that it’s acceptable by getting a friend to knock and enter through the front door. You can then give your Chihuahua a treat.

Give your Chihuahua access to the area only when he is not acting aggressively if he has a particular location where he acts aggressively, such as a corner of the living room. If he acts aggressively around a toy, you can do the same thing by taking the item away and putting it back after he is calm. Some experts also advocate making dogs “work” for their toys and belongings by having them follow simple obedience instructions like sit or heel before rewarding them with the toy or object. This can stop territorial aggression together with regular socialization and rewarding behavior.

When your Chihuahua is eating, slowly approach him with a reward to avoid territorial aggressiveness. He should briefly stop eating to accept the food, then you should go and wait for a while before coming back with another treat. This demonstrates to your Chihuahua that intruders aren’t always terrible when they enter his domain.


Chihuahuas may become violent when they are ill or have certain disorders. One such illness that can increase a dog’s propensity for biting is hypothyroidism. The thyroid gland, a tiny gland close to the larynx (voice box), is in charge of creating thyroid hormones, which control normal metabolic processes. Hypothyroidism happens when the thyroid gland doesn’t generate enough of these hormones.

Although it mainly affects larger breeds, hypothyroidism can also affect Chihuahuas. If your Chihuahua has this condition, a quick blood test at the vet’s office will be able to detect it. Levothyroxine (Soloxine), a thyroid hormone supplement, is frequently recommended to treat hypothyroidism in dogs.

Hypothyroidism symptoms could include:

  • aggressive attitude
  • Lethargy
  • shedding excessively and losing hair
  • Unexpected weight gain
  • skin hyperpigmentation
  • High triglycerides
  • Anemia

Another illness that has been connected to canine aggression is Lyme disease. It is spread by the bite of an infected tick and can result in neurological symptoms like irritability, disorientation, and aggression as well as swollen joints, enlarged lymph nodes, tiredness, and lack of appetite. Only 5–10% of canines with Lyme disease, though, exhibit symptoms.

Although there is a vaccine for Lyme disease, due to the possibility of unfavorable reactions, many veterinarians advise traditional tick preventive methods instead.

Teaching Your Chihuahua Not to Bite

No single teaching method will prevent all Chihuahuas from biting. Dogs bite for a variety of reasons, and depending on the cause, there are various ways to stop this habit. Having said that, using the following advice can significantly lessen many incidences of biting and other aggressive behaviors in Chihuahuas.

Don’t Punish for Growling

Many owners reprimand or otherwise discipline their Chihuahuas when they growl. By doing this, they take away a crucial precursor to biting. Your Chihuahua might not bite the next time he’s agitated if you teach him that growling is bad. While the threat of biting remains, the warning sign of growling is no longer present.

If you’re trying to teach your Chihuahua not to bite, letting him growl may seem counterproductive, but it’s actually helpful. In order to prevent getting bitten, owners can instruct their kids to back away from the Chihuahua when he growls.

The reason for his aggressiveness may also be revealed by his growl. Your Chihuahua may be experiencing discomfort from an injury or a medical issue if he growls when lifted up. His hostility is territorial if he growls when another pet approaches his kennel.

Teach Bite Inhibition

The capacity of a dog to control the force of his bite is known as bite inhibition. For example, your Chihuahua shouldn’t use his entire jaw force to bite your palm when you’re giving him a treat. He will receive the treat more cautiously to avoid hurting you if he has learned bite inhibition. The objective is to teach your Chihuahua to manage the force of his bite rather than to stop him from biting.

Early on, while nursing and playing with their littermates, puppies acquire biting inhibition. The same applies for puppies nursing on their mother: biting the mother too forcefully may make her to stand up and move away. If a puppy bites one of his littermates too hard, the other littermate may put out a high-pitched shriek, saying “You bit me too hard— and it hurt!” A puppy must learn to control his bite if he wants to play and feed.

Puppies should remain with their mother for at least eight weeks for reasons like this. A puppy has less chance of learning biting inhibition through play and feeding if removed too soon. The same is true for children who are born alone and lack playmates.

Following these three guidelines can help you teach biting inhibition:

  1. React to incisive bites . You should ignore your Chihuahua for a few minutes after he bites you too firmly by exclaiming, “Ouch, that hurt!” and withdrawing your hand away in response.
  2. Maintain a steady training schedule. . When training your Chihuahua bite inhibition, consistency is essential. He becomes confused when you answer with a loud “Ouch” on one occasion but not the next.
  3. reinforce as you get older . The optimum time to teach a puppy bite inhibition is when he or she is still a young puppy. Even when your Chihuahua is an adult, you should keep practicing it.


Chihuahuas are much If they aren’t socialized, they are more likely to behave aggressively. A Chihuahua is more likely to exhibit fear-based aggressiveness, such as biting an unfamiliar person’s hand, if he isn’t introduced to other people, animals, and situations.

Researchers from Tufts University’s Cummings School of Veterinary Medicine discovered in one study that puppies who were not socialized were 580 times more likely to grow up with aggressiveness issues.

Showing your Chihuahua that other people and animals aren’t bad is the goal of socialization, ideally while he’s still a puppy. Between the ages of three and sixteen weeks, when puppies are most susceptible to socialization, is a crucial period for preventing aggression. If your Chihuahua has favorable interactions with other animals and humans when he’s young, he’ll grow to be more accepting of strangers in the future.

Following are some guidelines for socializing your Chihuahua:

  • Before exposing your Chihuahua to other people and animals, be sure he has received all of his necessary shots.
  • Take your Chihuahua to the pet store.
  • Take your Chihuahua along for the ride, but don’t leave him in the vehicle.
  • Take your Chihuahua on walks in places like dog parks, your neighborhood, forest trails, etc.
  • Play fetch outside with your Chihuahua.
  • Walk your Chihuahua around the perimeter of the fence before bringing him to the dog park.
  • Visit friends’ and family’s houses with your Chihuahua.
  • Encourage visitors to your home—friends or family members—to play with your Chihuahua.
  • Enroll in a class for group-based obedience instruction.
  • Treats should be given to your Chihuahua after each socialising activity.


Chihuahua aggression may be decreased by spaying or neutering. In a study by University of California researchers, intermale hostility was found to be reduced in 60% of male canines who were neutered, with 25% experiencing a quick drop and 35% seeing a gradual decline.

As a result of neutering, testosterone levels fall, lessening the aggressive, hyperactive, and urinating to mark territorial behavior that is linked to this hormone.

A female Chihuahua who has been spayed will no longer experience her heat cycle or the related behaviors. Additionally, it might lessen female hormone-driven behaviors like nest-guarding during a phony pregnancy.

It was once widely accepted that male dogs should be neutered prior to reaching adolescence in order to avoid these behavioral issues. But according to a research published by the American Veterinary Medical Association (AMVA), neutering male dogs after they reach adulthood can reduce aggression just as well as neutering them before they reach puberty.

Professional Help for Biting and Aggression


When everything else fails, get help for your Chihuahua’s behavior from a specialist. The American Society for the Prevention of Cruelty to Animals (ASPCA) advises speaking with either a board-certified veterinary behaviorist or a Certified Applied Animal Behaviorist (CAAB).
