Where Does the Chihuahua Dog Belong to?

The Chihuahua dog originally belongs to Mexico and is called after the state of Chihuahua. The American Kennel Club (AKC) recognised the first Chihuahua dog in the United States in 1904, but the breed has a long history. Evidence suggests that this species is a descendant of the old Techichi, a Mexican breed that dates back to the 19th century. It was so popular during the period that it was depicted in paintings and artefacts across Mesoamerican civilization. The Techichi escaped to Mexico's countryside after the Aztecs conquered them. The Chihuahua is one of the world's tiniest dog breeds. The small chihuahua will fit in a purse or a bag. There are many different types of chihuahuas so let us explore more about their habitat, diet, and nature.

Nature and Life Cycle of Chihuahua Smallest Dog

  • Different Breeds and Their skin type- Registries' current breed standards call for an "apple-head" or "apple-dome" skull conformation. These Small Chihuahua have a high, dramatically rounded skull with huge, wide eyes and large, erect ears. The muzzle meets the skull at a nearly 90-degree angle, providing a well-defined halt. While the old chihuahua which are the dogs with a flat-topped skull, more widely set eyes, broader ears, and longer, more slender legs, such as the older "deer" form, may still be registered. Black, Blue & Tan, Black & Tan, Chocolate, Chocolate & Tan, Cream, Fawn, Fawn & White, and Red are the seven hues available in Chihuahuas. Black Brindling, Black Mask, Black Sabling, Merle Markings, Spotted on White, and White Markings are the six standard markings seen on the mini chihuahua dog. 

  • Physical Appearance- Chihuahuas come in two varieties- the Smooth Coat variety that is named so due to the smooth-haired skin and Long Coat or the long-haired small chihuahua. Both the Smooth and Long Coats have their own distinct characteristics and are equally easy to keep clean and groomed. The word "smooth coat" does not necessarily imply that the hair is smooth; the texture of the hair can range from velvety to whiskery. Long Haired Chihuahuas have softer, fine-guard hairs and a downy undercoat, giving them a fluffy appearance. Long Haired Chihuahuas, unlike many other longhaired breeds, require little maintenance and no trimming. In contrast to popular assumption, longhaired dogs shed less than their shorthaired counterparts. It could take three years or more for a complete longhaired coat to grow.

  • Reproduction or the heat cycle of a chihuahua- 

  1. Stage 1- The commencement of the heat period, when the dog's body prepares to mate, is known as proestrus. A swollen vulva, blood-tinged discharge, extensive licking of the vaginal area, clinging behaviour, and hostility toward male dogs are all signs of this period. The chihuahua's tail may also be held close to her body.

  2. Stage 2- The estrus period is when a female dog is ready to mate and is receptive to males. You may notice that the dog is urinating more frequently than usual, as she is marking spots to show that she is ready to reproduce. Her vaginal discharge will slow and possibly turn to a straw colour, despite the fact that she may leave urine marks in some spots. When the dog is ready to mate, she will approach males with her tail tucked to the side, but she will attack other females.

  3. Stage 3- Following the "in heat" period, this phase allows the dog's body to either return to normal or progress into pregnancy. Her vulva will revert to its original size, and the vaginal discharge will stop.

  4. Stage 4- Post the heat cycle the last stage is the anestrus phase. Anestrus is a dormant period with no visible symptoms of hormonal or sexual activity.

  • Food and Diet of all types of Chihuahua breed- Based on its size, age, and activity level, the Chihuahua should eat no more than a half cup of high-quality dry food every day. Intermittent treats can also be given as part of a positive training programme. If the dog begins to acquire weight, it may be necessary to reduce the number of calories given to him. The veterinarian can assist the owner in determining an acceptable diet for the chihuahua dog.

  • Chihuahua Dog Training And Exercise- All types of chihuahua require a minimum exercise and training to keep them active and engaged and not fall into the vicious cycle of lethargy. The Chihuahua, despite its charismatic and comical reputation, is a smart and observant dog who only wants to please its master. Because of its delicate disposition, this breed requires a firm but sympathetic approach. Allowing the dog to goof about is fine, but don't let it get away with it. Setting boundaries with positive training is surprisingly effective. It's even possible to teach this breed a variety of tricks and sports, as long as they're done safely. A low to medium quantity of exercise per day is usually sufficient for the Chihuahua. Toys or time spent playing in modest indoor or outdoor places should suffice. Daily 30-minute walks are always recommended to burn off excess energy and maintain a healthy weight but don't overwork the dog. Its compact structure isn't designed for a strenuous workout. If the dog starts panting heavily, it's time to stop. It's also a good idea to have the chihuahua dog ready for inclement weather.

  • Grooming The Varying Types of Chihuahua- The frequency with which it is groomed is determined by the length of its coat. The silky sheen brushes the Chihuahua on a regular basis, not every week, but enough to remove any tangles or mats. Long hair necessitates more regular brushing, roughly once a week. Bathing, nail trimming, and ear cleaning should all be done on a regular basis to maintain both sorts of dogs healthy. However, like with many smaller breeds, dental care is the most significant grooming requirement. Brush the Chihuahua dog's teeth at least twice or three times a week, and for best results, brush them daily. To keep the teeth clean, the veterinarian may suggest particular treats. 

  • Nature and Behavioural Traits of Chihuahua- The Chihuahua has a kind, devoted nature that strives to please its owner, with whom it has formed a strong attachment. This breed is aggressive for its small size, but it has a quirky and lively personality. Its versatility is one of its most enticing characteristics. It may easily unwind and unwind with its user, or it can have some fun and exercise. The Chihuahua is also highly diligent and receptive to commands, which is great for owners who wish to train their dogs. This breed, for all of its outgoing nature around friends and relatives, maybe apprehensive of strangers. It takes time to acquire the trust of this breed. That is why, despite its small size, the Chihuahua makes an excellent guard dog.

Possible Health Problems Faced By Chihuahua

  • Many chihuahua owners have lost their beloved pets due to bacterial and viral illnesses. Rabies, parvovirus, distemper, sepsis, and leptospirosis are the most prevalent (for all dogs). Taking any of them for granted can result in the early death of one's pet, thus it's not a good idea to ignore them. 

  • Periodontal disease is the most common form of tooth and gum disease in Chihuahuas and other small dogs. While tooth and gum disease will not kill them, the infections that ensue if left untreated may. Pneumonia is one of the most serious illnesses, with a significant death rate in dogs.

  • A dislocating kneecap, also known as a luxating patella, is a common condition in chihuahuas and other tiny dog breeds. To prevent the pain, your dog may hobble or hang one foot in the air. This health issue will have a significant impact on your Chi's as Chihuahuas are affectionately referred to as quality of life.

  • Valve disease is a type of heart disease that affects Chihuahuas and other tiny dog breeds. It can lead to cardiac failure if left untreated. The key to extending the longevity of a chihuahua is early discovery and treatment.

  • Chihuahuas and other small dog breeds are susceptible to valve disease, which is a type of heart disease. If left untreated, it might lead to heart failure. Early detection and treatment are essential for a chihuahua's longevity.

  • When the trachea or the windpipe of your chihuahua collapses, he or she will have difficulty breathing. A honking cough is the most obvious symptom of this issue. A collapsed windpipe is a medical emergency that requires quick attention in order to save your pet's life.

  • During the colder months, this is a common occurrence. Because of their small stature and intense metabolism, they lose heat quickly. Although this isn't a health issue, it can lead to one if you don't warm up your dog. 

Interesting Facts About Chihuahua Dog

  1. Gidget, the famous Chihuahua who starred in Taco Bell ads, was a female Chihuahua (who lived from 1994 to 2009). 

  2. The Chihuahua is the only breed that is "clannish," meaning it prefers the companionship of other Chihuahuas to that of other breeds.

  3. Most Chihuahuas are born with a hole in their skull, which is not unique to the breed. It's called a molera, or "soft spot," and it affects 80 percent to 90 percent of all Chihuahua puppies. The molera normally closes as the pup grows older, but some Chis have this cranial opening their entire lives.

  4. The dog in its early form was most likely much larger than the ones we see now. The breed reduced in size after being mixed with a tiny hairless dog from Asia, possibly a Chinese crest imported to Alaska across the Bering Strait.

  5. While specialists are confident that the little dogs originated in Mexico, the path they followed to Europe is less certain. Some link to Christopher Columbus, who mentioned the little dogs in a letter to the King of Spain. It's conceivable he took some of the dogs home with him from his travels.

  6. Moonie, a Chihuahua that lived from 1998 to 2016, co-starred with Reese Witherspoon in the two Legally Blonde films. For a while, he actually lived with Gidget.

  7. Chihuahuas are easy to train due to their intelligence. In fact, they perform admirably in agility and obedience competitions and can serve as excellent service dogs, particularly for the blind and as emotional support animals.

  8. Chihuahuas have the largest brain in the dog world when compared to their bodies. They have a quick wit and are simple to train. However, due to a small bladder and a stubborn disposition, they are difficult to housebreak. They don't like rain or cold because they're desert dogs.

  9. Tinkerbelle, Paris Hilton's Chihuahua, starred alongside her on the reality show "The Simple Life."

  10. Puppies' ears are floppy after they are born. They begin to stand straight as they grow older, with fully erect ears appearing about six months of age.

  11. Separation anxiety and a fear of traffic or crowds are more common among Chihuahuas.

  12. It is a very saddening fact that Chihuahuas are the second most euthanized breed after Pitbulls.

FAQs on Chihuahua

1. How Can I Know Which Chihuahua Breed I Have?

Answer. Because chihuahuas are classed in two ways, determining the sort of chihuahua you have is pretty simple. One way is based on the shape of their heads, which can be either apple or deer; the other is based on their coat, which can be long-haired or smooth.

2. Are Chihuahuas Suitable as Pets?

Answer. The choice of a pet depends on the breeds of dogs you're interested in. The Chihuahua may be the appropriate dog for you if you desire a little friend who will follow you practically everywhere. Chihuahuas make wonderful pet dogs. They enjoy being noticed and are devoted to their owners. Chihuahuas make terrific family pets when treated with respect, but they have a reputation for snapping at strangers or little children who may be a threat to their diminutive size. This breed is alert, sensitive, charming, and playful, among other attributes.

3. Why are Chihuahuas so Abrasive?

Answer. Although a Chihuahua is not as dangerous as a larger dog, it can nevertheless attack and injure people, particularly children and the elderly. Chihuahuas can be aggressive for the same reasons that any dog can be aggressive and that can be fear, territorial behaviour, or a desire to display dominance. Male dogs are more inclined to attack other male dogs or chase females about the house. Neutering the dog, once again, may help to reduce some of this behaviour.

4. What Common Problems Do Chihuahuas Have?

Answer. Chihuahuas are rather fragile dogs (owing to their small size). They have serious dental problems that require constant attention regularly. And they can rather come across as standoffish and reserved around strangers. Heart disease is one of the leading causes of death in chihuahuas. Many chihuahuas will develop this condition once they reach their mature years that are 14 years old or more. Heart failure, arrhythmia, and heart valve issues are all examples of heart disease.
