History of the Chihuahua

The Chihuahua is generally considered the smallest dog breed in the world, and its history is as colorful and fascinating as the breed itself. Originating from the Mexican state of Chihuahua, the breed’s ancestry can be traced back to the ancient civilizations of the Toltecs and the Aztecs. The Chihuahua’s predecessors were believed to be the Techichi dogs, small, silent companions kept by the Toltec people as early as the 9th century.

When the Aztecs conquered the Toltecs, they absorbed the Techichi into their society, valuing the dogs for their religious significance and their role as companions. Historical records suggest the Aztecs believed Techichis had mystical powers, including the ability to guide the souls of the dead through the underworld.

The modern Chihuahua’s story began in the mid-19th century with their “discovery” in local markets by visiting Americans. The visitors from El Norte brought the tiny canines back to the United States where they were an instant hit. The Chihuahua’s popularity quickly increased north of the border, winning many admirers among dog show exhibitors.

The American Kennel Club (AKC) officially recognized the Chihuahua as a breed in 1904. Since then, the Chihuahua has become a beloved companion in homes worldwide, admired for its loyalty, intelligence, and spirited personality. Despite their petite size, Chihuahuas have a bold and confident demeanor, often unaware of their own size limitations.

Appearances in various media have had a tremendous effect on the breed’s popularity, making it an instantly recognizable icon. Today, Chihuahuas are not only cherished companions and commercial mascots, they’re  also determined competitors at dog shows and in various dog sports where they display their charm, intelligence, and versatility.

The Chihuahua’s rich history, from ancient Mexican civilizations to modern-day Main Street, underscores the breed’s enduring appeal and the special place it holds in the hearts of dog enthusiasts around the world.

General Appearance

Height & Weight

The Chihuahua is characteristically small but should not be delicate or fragile in appearance. Male and female Chihuahuas generally vary in height from 5 to 8 inches tall at the shoulders. Their weight is ideally between 2 and 6 pounds. Dogs weighing more than 6 pounds are unacceptable.

Proportion & Substance

The Chihuahua exhibits a compact body with well-sprung and rounded ribs. The body should be slightly longer than tall, measured from the point of shoulder to the point of the buttocks. Males can have somewhat shorter bodies than females. Overall balance, without exaggeration, is essential in this small but substantial dog. Despite their light weight, Chihuahuas should not appear frail or excessively thin; they need to display a symmetry, soundness, and vigor.

Coat Texture, Colors & Markings

Texture: The Chihuahua’s coat comes in two varieties: Smooth and Long. The Smooth Coat should be soft, close, and glossy, with a ruff on the neck. Heavier coats with undercoats are acceptable, and the hair on the tail is often “furry.” The Long Coat is characterized by its soft texture, either flat or slightly curly. Ideally, there’s an undercoat. Fringing on the ears, a ruff on the neck, feathering on the feet and legs, “pants” on the hind legs, and a plume on the tail give this variety its distinctive appearance. Other than the coat, both varieties are identical and both regular grooming to maintain their condition and appearance.

  • Expression: Alert, luminous, and full of intelligence, the Chihuahua’s expression is keen and inquisitive, reflecting the breed’s lively and perceptive nature. It is described as “saucy” by preservation breeders.
  • Eyes: Full and round, but not protruding, the eyes are set well apart, luminous in color, and convey an expressive and endearing quality.
  • Ears: Large, erect, and set at an angle to give a flared appearance, the ears are a significant aspect of Chihuahua expression and convey alertness.
  • Muzzle: Moderately short and slightly pointed, the muzzle extends from a well-defined stop at a 90-degree angle.
  • Nose: Full and never pointed, the nose is black or self-colored in dogs with blue, chocolate, and mole coats. Blond dogs can have a pink-colored nose.

Tail

The tail of the Chihuahua is moderately long and carried in either a loop over the back, with the tip just touching the back, or in a more relaxed sickle shape. The tail should never be tucked between the legs or curled below the backline. A bobtail, and a tail that has been docked, is not acceptable.

Whether the Chihuahua has a long or smooth coat influences the tail’s appearance. Long Coats feature a plume of long and full fringes, whereas the Smooth Coats feature a tail that’s simply furry. The natural carriage and appearance of the tail are essential characteristics, contributing significantly to the Chihuahua’s lively and confident demeanor.

The Chihuahua – What to Consider?

The Chihuahua, renowned for its compact size and vivacious character, is beloved by many and often chosen for both companionship and competitive activities. Prospective owners must appreciate the breed’s distinctive personality traits and requirements to foster a harmonious relationship in the home and when out and about.

Home Life

Interaction With Family

The level of affection a breed typically shows towards family members and familiar individuals will vary. While some breeds may only show genuine warmth towards their owner, remaining standoffish with strangers, other breeds will treat everyone they meet as if they are their closest friend.

The degree to which a breed will typically be patient with young children, and its overall suitability as a family member, will vary. It is important to always supervise interactions between dogs and the kids in the house, as well as with children who are not accustomed to being around dogs.
Not Recommended Dependable With Children

Upkeep

Amount Of Shedding

The amount of hair that a dog sheds will typically depend on its breed. Heavy-shedding breeds require more frequent brushing, have a higher chance of activating specific allergies, and often necessitate more frequent use of the vacuum cleaner and lint rollers.

Behavior

Personality

Trainability Level

The ease with which a dog can be trained and its eagerness to learn new skills can depend on the breed. Some breeds are naturally inclined to please their owners and will readily accept training, while others tend to follow their own desires, often showing independence in how, when, and where they choose to do things.
Stubborn Eager

Barking Level

The frequency of vocalization, including barking and howling, will vary from breed to breed. Some may bark at each person who passes by and every bird in the sky, while others will typically bark only for a good reason. Additionally, a few breeds that do not typically bark will still be vocal, using different sounds to communicate.
Quiet Vocal

Energy Level

The level of physical exercise and mental engagement required will depend on the breed. High-energy breeds are always on the go. They are enthusiastic about their next activity and tend to be busy most of the time, running, jumping, and playing throughout the day. In contrast, low-energy breeds are akin to couch potatoes, content to just lounge around and take naps throughout the day.

Need For Mental Stimulation

The extent of mental stimulation needed to keep a dog content and healthy will vary by breed. Dogs bred for specific purposes may need tasks involving decision-making, problem-solving, and concentration. Without sufficient mental exercise, these dogs can resort to creating their own activities to engage their minds, resulting in unwanted behaviors like chewing, digging, and escaping.
Minimal Engagement Intensive Interaction

Chihuahua Health

Chihuahuas are generally considered to be healthy and resilient dogs, with a well-cared-for individual typically enjoying a lifespan of 14 to 16 years. Nevertheless, these dogs do have a few breed-specific health issues that owners should be mindful of to ensure their pet’s longevity and well-being. Partnering with a reputable breeder and a knowledgeable veterinarian is crucial for monitoring and addressing any health concerns promptly.

Potential Health Risks

Chihuahuas, like all breeds and mixed breeds, many be predisposed to certain health conditions. Owners should be vigilant and proactive in monitoring their dog for signs of common health issues to ensure early detection and treatment. Here are some of the potential health risks associated with Chihuahuas:

  • Patellar Luxation: This is a common condition in small dogs where the kneecap dislocates or moves out of its normal alignment.
  • Hypoglycemia: Maintaining proper blood sugar levels is crucial, especially in smaller Chihuahuas and puppies. Symptoms include lethargy, muscle weakness, and even seizures.
  • Heart Problems: These include congenital heart defects and heart murmurs, which have been known to affect the breed.
  • Dental Issues: Due to their small jaws, Chihuahuas are prone to overcrowded teeth, leading to dental disease if proper care is not maintained.
  • Hydrocephalus: Also known as “water on the brain,” this condition can be found in the breed, especially those with an extreme “apple” shape to their skull.
  • Tracheal Collapse: This is a condition where the tracheal rings weaken, leading to breathing difficulties.
  • Eye Diseases: These include cataracts and progressive retinal atrophy, which can lead to vision loss if not addressed.

Regular veterinary check-ups are essential for early detection and management of these conditions. Veterinarians can provide guidance on preventive care, including proper nutrition, exercise, and dental hygiene, to help mitigate the risks of these health and other issues. Addressing any concern promptly can greatly enhance the quality of life for the Chihuahua and support a long, healthy relationship with its family.

Chihuahua Personality

Understanding the personality of a Chihuahua is crucial for anyone who is considering this breed as a companion. Despite the breed’s small size, Chis are known for their big personalities, brimming with confidence and charm. These dogs are fiercely loyal to their owners, often forming a strong, inseparable bond with their primary caretaker. This loyalty can sometimes manifest as over-protectiveness, making early socialization and training key to developing a well-rounded dog.

Chihuahuas can be ideal for novice owners due to their size and manageability, but their strong-willed nature requires consistent, gentle training. They are sensitive dogs that do not respond well to harsh discipline. Their sensitivity also extends to their environment; Chihuahuas prefer warmth and can become anxious or shivery in cold climates.

Though small, Chihuahuas are not passive dogs. They have a moderate-to-high energy level and enjoy being engaged in all sorts of activities. Despite their size, they are often good with children, especially if raised with them. However, all interactions should be supervised to make sure the dog is not accidentally injured due to its tiny size.

When it comes to other dogs and strangers, a Chihuahua’s reaction can vary. Some are very sociable and enjoy the company of other dogs, while others may be more reserved or even standoffish. Early socialization can help a Chihuahua become more accustomed to a variety of people and animals, reducing the chance of fearful or aggressive reactions.

Chihuahua Feeding & Nutrition

Proper feeding and nutrition are fundamental to a Chihuahua’s health and well-being. Given the breed’s small size, these dogs have specific dietary needs that must be met to ensure they maintain optimal health, energy, and longevity. The amount and type of food given to a Chihuahua can significantly impact its overall health, weight, and energy level.

For Chihuahua puppies, it’s crucial to provide a high-quality puppy formula that supports rapid growth and development. Puppies should be fed more frequently, typically three to four times a day, to keep up with their energy demands and support healthy growth. As they transition to adulthood, the frequency of mealtimes can be reduced to twice daily.

Adult Chihuahuas require a balanced diet that includes all necessary nutrients in the right proportions. The amount of food that’s needed depends on the dog’s age, size, activity level, and metabolism. On average, a Chi needs about ¼ to ½ cup of high-quality dry dog food each day, divided into two meals. This can vary, however, so it’s important to adjust the food amount based on the dog’s individual needs and to consult with the dog’s breeder or veterinarian for specific dietary recommendations.

Monitoring a Chihuahua’s weight is also vital, as obesity can lead to numerous health issues, including joint problems, diabetes, and heart disease. Treats should be given sparingly and should account for no more than 10 percent of a Chihuahua’s daily caloric intake.

In addition to providing the right amount of food, having access to fresh, clean water at all times is essential for a Chihuahua’s overall health. Regular veterinary exams can help to monitor the dog’s nutritional needs, and they can allow for adjustments to be made that will address any potential concerns.

Chihuahua Training

Training a Chihuahua requires patience, consistency, and an understanding of the breed’s unique temperament. Training should begin early to establish good habits and to
