Chihuahua: Characteristics of my little companion

Origin and history of the Chihuahua:

The Chihuahua is a small breed of dog known for its tiny size and distinctive personality. The breed's origin and history can be traced back to the ancient civilizations of Central America, particularly the region that is now Mexico. While there is some debate and speculation about the exact origin of the Chihuahua, several theories exist.

One theory suggests that the Chihuahua's ancestors can be traced to the Techichi, a small companion dog kept by the ancient Toltec civilization in Mexico. The Techichi dogs were believed to have been bred and cherished by various Mesoamerican cultures, including the Mayans and the Aztecs. These small dogs played important roles in religious ceremonies and were believed to possess healing powers.

Another theory proposes that the Chihuahua's ancestors are descended from the small dogs that were domesticated by the ancient peoples of China and then brought to the Americas by explorers or traders. This theory suggests that the Chinese Crested and the Mexican Hairless dogs might have contributed to the Chihuahua's lineage.

The modern Chihuahua breed as we know it today emerged in the mid-19th century in the Mexican state of Chihuahua, from which it derives its name. It is believed that the breed was developed through a combination of selective breeding and the introduction of small European toy breeds, such as the Papillon and the Pomeranian.

The Chihuahua gained popularity in the United States during the late 19th and early 20th centuries. American tourists visiting Mexico discovered the breed and brought them back to the U.S. Over time, the Chihuahua's popularity grew, and the breed became recognized by major kennel clubs.

In 1904, the American Kennel Club (AKC) officially recognized the Chihuahua as a breed. Since then, the Chihuahua has remained a popular choice for a companion dog and has achieved recognition worldwide.

Today, the Chihuahua is known for its small size, lively and alert personality, and a variety of coat types, including both short-haired and long-haired varieties. They are cherished as beloved pets and are often seen in movies, television shows, and celebrity circles.

Chihuahua, with short hair or long hair?

The main difference between Chihuahuas with hair and those without hair lies in their coat type and appearance. Here's a comparison between the two:

Long-Haired Chihuahuas:

  • Coat: Long-haired Chihuahuas have a soft and silky coat that can range from moderately long to very long. Their fur tends to be fine and flowing.
  • Grooming: Due to their longer hair, long-haired Chihuahuas require more grooming compared to their short-haired counterparts. Regular brushing is necessary to prevent matting and tangles.
  • Appearance: Long-haired Chihuahuas have a more glamorous appearance with their flowing locks. Their fur can come in various colors and patterns, adding to their overall charm.
  • Insulation: The longer hair provides some insulation, which can be beneficial in colder climates or during cooler seasons.


Hairless Chihuahuas:

  • Coat: Hairless Chihuahuas have little to no hair on their bodies. They may have some hair on certain areas such as their head, tail, or feet, but it is typically minimal.
  • Skin care: Without a protective coat, hairless Chihuahuas require special attention to their skin. Regular moisturizing and sun protection are necessary to keep their skin healthy and protected from sunburn or dryness. Bathing should be done with mild products to prevent irritation.
  • Sensitivity: Due to their lack of fur, hairless Chihuahuas can be more sensitive to temperature extremes. They may require extra layers or clothing to keep warm in colder weather and protection from excessive sun exposure.
  • Allergies: Some people with allergies to dog hair may find hairless Chihuahuas more suitable, as they produce less dander. However, individual allergies can still vary.

It's worth noting that both long-haired and hairless Chihuahuas share similar characteristics in terms of temperament, behavior, and health concerns. The choice between the two coat types is primarily a matter of personal preference and the level of grooming and maintenance one is willing to undertake.

Characteristics of the Chihuahua:

Chihuahuas have distinct characteristics that set them apart from other dog breeds. Here are some common traits of Chihuahuas:

  • Size: Chihuahuas are known for their small size. They are one of the smallest dog breeds, typically weighing between 2 to 6 pounds (0.9 to 2.7 kilograms). They are considered a toy breed.
  • Appearance: Chihuahuas have a compact and well-proportioned body. They have a rounded skull, large and expressive eyes, and erect, pointed ears. Chihuahuas can have either a smooth, short-haired coat or a long-haired coat, with a variety of colors and patterns.
  • Temperament: Chihuahuas often have a big personality despite their small size. They are generally alert, confident, and lively dogs. They can be quite affectionate and form strong bonds with their owners, often preferring the company of their human family over other dogs. Chihuahuas are known to be loyal and protective of their owners, sometimes even exhibiting some degree of jealousy.
  • Intelligence: Chihuahuas are generally intelligent dogs and can be quick learners. They can pick up commands and tricks with proper training and positive reinforcement. However, they can also be stubborn at times, so consistent and patient training methods are recommended.
  • Energy level: Chihuahuas are typically energetic dogs. They enjoy playtime and exercise but can also adapt to a more sedentary lifestyle if provided with mental stimulation and short daily walks. They are well-suited for apartment living due to their small size and exercise requirements.
  • Socialization: Chihuahuas benefit from early socialization to ensure they become well-rounded and confident dogs. Proper exposure to various people, animals, and environments can help prevent them from becoming overly anxious or shy.
  • Health: Chihuahuas, like many small dog breeds, can be prone to certain health issues such as dental problems, patellar luxation (kneecap dislocation), hypoglycemia (low blood sugar), heart conditions, and tracheal collapse. Regular veterinary care, a balanced diet, and maintaining a healthy weight are important for their overall well-being.

It's important to remember that individual Chihuahuas can have unique personalities and characteristics, and not all Chihuahuas may exhibit every trait mentioned above. Early socialization, training, and proper care are essential to ensuring a well-adjusted and happy Chihuahua.

Behavior of the Chihuahua:

The behavior of a Chihuahua can vary from dog to dog, but there are some common behavioral traits associated with the breed. Here are some characteristics of Chihuahua behavior:

  • Alertness: Chihuahuas are known for their keen alertness. They are typically very attentive and have a strong tendency to be aware of their surroundings. They may bark or alert their owners to any perceived threats or unfamiliar stimuli.
  • Confidence: Despite their small size, Chihuahuas often exhibit a high level of confidence. They can be quite bold and fearless, sometimes even displaying a "big dog" attitude. This confidence can make them unafraid to approach larger dogs or unfamiliar situations.
  • Loyal and Protective: Chihuahuas often develop strong bonds with their owners and can be fiercely loyal. They are known to be protective of their loved ones and may display protective behaviors such as barking, growling, or trying to assert dominance when they feel their owners are threatened.
  • Affectionate: Chihuahuas are generally affectionate dogs. They enjoy being close to their owners and often seek physical contact, whether it's sitting on laps or snuggling under blankets. They can form deep emotional attachments and can be quite loving and devoted companions.
  • Independent streak: Chihuahuas can also exhibit an independent nature. They may display a certain level of self-reliance and may prefer having their own space or alone time. However, they still require social interaction, companionship, and attention from their owners to prevent feelings of loneliness or isolation.
  • Potential for stubbornness: Chihuahuas are intelligent but can also be stubborn. They may have their own ideas about things and may require patient and consistent training methods. Positive reinforcement techniques, such as treats and praise, tend to work well with Chihuahuas.
  • Sensitivity: Chihuahuas can be sensitive dogs, both physically and emotionally. They may be more prone to stress or anxiety in certain situations, and loud noises or sudden changes in their environment can startle them. Gentle handling, a calm environment, and a predictable routine can help them feel more secure.


It's important to note that individual Chihuahuas may display variations in behavior based on their genetics, socialization, and upbringing. Early socialization, positive reinforcement training, and providing a stable and loving environment are crucial for raising a well-behaved and balanced Chihuahua.

How is the health of the Chihuahua?

Chihuahuas are generally a healthy breed, but like all dogs, they can be prone to certain health issues. Here are some common health concerns associated with Chihuahuas:

  • Dental problems: Chihuahuas are susceptible to dental issues such as tooth decay, gum disease, and tooth loss. It's important to establish a regular dental care routine, including regular brushing and professional dental cleanings as recommended by a veterinarian.
  • Patellar luxation: This condition involves the dislocation of the kneecap and is common in small breeds, including Chihuahuas. It can cause lameness or difficulty in walking. Severe cases may require surgical intervention.
  • Heart conditions: Chihuahuas can be prone to heart-related issues, including heart murmurs, mitral valve disease, and congestive heart failure. Regular veterinary check-ups and diagnostic screenings can help identify and manage these conditions.
  • Hypoglycemia: Chihuahuas have a higher risk of developing low blood sugar levels, especially as puppies. This can cause weakness, lethargy, seizures, and even coma in severe cases. Feeding them small, frequent meals and monitoring their blood sugar levels can help prevent hypoglycemic episodes.
  • Tracheal collapse: Chihuahuas may have a weakness in their tracheal cartilage, leading to a collapsed or narrowed windpipe. This can result in coughing, wheezing, and difficulty breathing, especially during exercise or excitement. Using a harness instead of a collar for walking and avoiding situations that cause excessive strain on the trachea can help manage this condition.
  • Eye problems: Chihuahuas can be prone to various eye conditions, including dry eye (keratoconjunctivitis sicca), cataracts, corneal ulcers, and progressive retinal atrophy. Regular eye examinations by a veterinarian are important to detect and manage these issues.
  • Obesity: Due to their small size, Chihuahuas are prone to weight gain and obesity. Obesity can lead to various health problems, including joint issues, heart disease, and diabetes. A balanced diet, portion control, and regular exercise are essential to maintain a healthy weight.

It's important to note that not all Chihuahuas will develop these health conditions, and responsible breeding practices, proper care, and regular veterinary check-ups can help minimize the risks.

Is it easy to educate a Chihuahua?

Educating a Chihuahua can be a mix of both ease and challenge, as it can vary from dog to dog. Here are some factors to consider when it comes to training a Chihuahua:

  • Intelligence: Chihuahuas are generally intelligent dogs and can learn quickly when provided with clear and consistent training. They can understand commands and pick up new skills relatively well.
  • Stubbornness: Chihuahuas can also be known for their stubborn streaks. They may have a strong will and independent nature, which can sometimes make them less responsive to training. This means that training sessions may require patience, persistence, and positive reinforcement techniques.
  • Socialization: Proper socialization is crucial for Chihuahuas, as they can be prone to shyness or fearfulness if not exposed to different people, animals, and environments early on. Socialization helps them develop into confident and well-behaved dogs.
  • Positive reinforcement: Chihuahuas respond well to positive reinforcement training methods, such as treats, praise, and rewards. They thrive on praise and enjoy the opportunity to earn rewards for good behavior. Harsh or punitive training methods are generally not recommended, as they can be counterproductive and damage the bond between the dog and the owner.
  • Consistency and routine: Chihuahuas benefit from consistent training routines and clear expectations. They respond well to a structured environment and thrive when given a routine they can rely on. Regular, short training sessions that are fun and engaging can be more effective than long, repetitive sessions.
  •  Attention span: Chihuahuas, like many small breeds, may have a shorter attention span compared to larger dogs. Keeping training sessions short, focused, and interactive can help maintain their interest and prevent them from becoming bored or disengaged.
  • House training: Chihuahuas can be successfully house trained, but it may require patience and consistency. They may need frequent bathroom breaks due to their small bladders. Using positive reinforcement, crate training, and establishing a consistent schedule can help with house training.
Some Chihuahuas may be more eager to please and trainable, while others may require more time and effort. It's important to approach training with a positive and patient mindset, focusing on building a strong bond and using reward-based techniques to achieve the desired results.
