The Chilean Fox Terrier is a breed of terrier developed in Chile by crossing the British Fox Terrier with local Chilean dogs. Already quite popular in Chile, where it is the only native breed, the Chilean Fox Terrier is rapidly growing in popularity throughout South America. The breed is best known for its presence in the popular comic strip Condorito, but is also known for its great skills as a vermin extaminer and suitability for life as a Companion Dog. Although the breed has not yet received formal accreditation with any of the major international canine organizations, it has a dedicated breed club to achieve this recognition. The Chilean Fox Terrier is also known as the Chilean Terrier, the Chilean Rat Terrier, the Chilean Rat Hunter, the Ratneiro and the Terrier Chileño.

Chilean Terrier Dog Breed


The Chilean Fox Terrier was first developed in the 19th century by crossing two different groups of dogs, the Fox Terriers of Britain and the native Chilean dogs. It is not clear when this breed first developed. Development probably began between 1790 and 1850, picking up the steam worn on time. The breed was well established by 1870, although some development and outcross almost certainly continued for several decades. Although the Chilean Fox Terrier is less than 200 years old, its ancestors can be traced back several centuries.

Although the modern Fox terrier can trace its lineage only in a few centuries, it is descended from a much older lineage. Originally, terriers were mainly kept by poor British farmers. Although it is not clear when the Terriers were first developed, they seem to have existed since at least the Roman Times, and probably earlier. Terriers were responsible for eradicating rodents and other small pests, an act on which these dogs excelled. The underground turret was named for being small enough to chase the mine, the terrier loosely named “”the one who goes to the ground.”” In the 16th and 17th centuries, British nobility began seriously hunting foxes for sport. Because English foxheads are too large to penetrate the fox’s burr, these early foxes began to use terriers to continue the chase. Eventually, a specific terrier developed specifically for fox hunting is known as the fox terrier. The fox terrier was quite a different animal at the time when members of the first breed were imported to Chile. The breed was almost always smooth-coated, and significantly more variable in appearance. In fact, many modern breeds were considered Fox Terriers at the time, including Jack Russell Terriers, Parson Russell Terriers and Smooth Fox Terriers. The Fox Terrier became so popular with the British upper classes that a large number of these dogs were kept mainly as companion animals. Despite individual dog’s primary use, in the 19th century almost all Fox terriers possessed the vermin eradication abilities of their ancestors, and many also used for fox hunting and companionship got rid of a barn or house of rodents Will get it done.

It is not entirely clear how the Fox Terrier was introduced to Chile, but it was the result of Chilean students studying in British schools, British traders active in Chile, and a small number of English and Irish immigrants. Shipping in the 19th century is very different than it is now. Under the best of circumstances, the journey from the United Kingdom to Chile took several weeks, and the trip was both quite expensive and quite dangerous. This meant that very few individual fox terriers would have arrived in the country. The first fox terriers in Chile were almost certainly confined to the country’s major ports, but they quickly spread to the surrounding rural areas. Although fox hunting has not become a popular sport in Chile, Chile quickly discovered that fox terriers were still quite useful. Just as their ancestors had been doing for untold centuries, Fox Terriers hunted in Chile and killed countless mice, rats, and other vermin. The small size and incredibly active nature of these dogs meant that they were equally suited to life in both the country and the city. In rural areas the breed helped prevent starvation and monetary losses from agricultural pests, and in urban areas the breed helped to prevent the spread of communicable and foodborne disease by killing potential carriers. Because not enough population arrived to maintain the Fox Terrier population, especially in more remote areas, they were heavily crossbred with local Chilean dogs.

General Appearance

The Chilean Fox Terrier is similar to its ancestors, the Smooth Fox Terrier and the Jack Russell Terrier, and most casual observers probably will not be able to distinguish between these breeds. However, this dog has a unique appearance, and experienced terrier fanatics will have little trouble telling these breeds after a quick examination. Part of this difference comes from the great variability of the Chilean Fox Terriers. Although standardization efforts have progressed well, this breed is much more variable than other modern terrier breeds.

The Chilean Fox Terrier is medium to small in size. Most men stand on shoulders between 12½ and 15 , with the ideal height being 13½ . Most women are between 11 and 13¾ , the ideal height being 12. . The male Chilean Fox Terrier in good condition typically weighs between 11 and 17 with pounds with the ideal weight being 14½ pounds. Women typically weigh between 8¾ pounds and 15ales pounds and the ideal weight is 12 pounds. This breed needs to be in a very high class ratio. Males are ideally of the same length from chest to rump as they are tall from floor to shoulder, and females are ideally 10 long every 9 . It is a very athletic and physically capable breed and should always appear as such. Chili Fox Terriers are very well muscled and physically fit dogs. It is a very strong built dog for a breed of this size, but should never be visible to a member of one breed.

A significant number of Chilean Fox Terriers are born naturally with short tails, and such dogs are preferred in the show ring. When not naturally small, the tail of a Chilean fox terrier is traditionally (essentially always) docked after the first or second vertex resulting in a small stub. However, this practice is falling out of favor and is actually banned in some countries. Natural tails of members of the breed that are not naturally fascinated are still significantly shorter and are usually straight with a curve.

Chili fox terriers are the dominant and most variable features of the face breed. The head and mocytes combine to form a triangular shape, wider behind the skull and narrowest at the tip of the muzzle. The forehead of this breed is usually slightly convex, revealing that the slope of the skull moves slowly into the snout. The snout itself is of medium to long length, but is usually somewhat shorter than the smooth fox terrier. The muzzle should always appear powerful enough to kill mice quickly and easily. The lips of this breed are tight-fitting. The nose of the Chili Fox Terrier is always tricolor and black on red dogs but brown on chocolate dogs. The ears of the Chilean Fox Terrier are usually short and set high, but their size is quite variable. Dogs call dogs that are ear-facing and partially standing but with drooping tips, but individual dogs are often fully retracted, backwards, sideways, rose shaped , Or come with a combination of two different ears. The Chili Fox Terrier has small and usually darker eyes, although lighter eyes are acceptable for dogs with lighter coats.

The Chili Fox Terrier’s coat is short, tight and shiny. The hair is somewhat finer towards the ears, neck, inner and lower back, and back of the thighs. The proper coloration of the Chili Fox Terrier is best described in the official breed standard. “The dominant color is white, covering the entire body including the neck and tail, and excluding the head and ears. This area presents black and tan, brown and tan and blue and tan colors. Tan marks should be distributed symmetrically on both sides of the eyes, on the cheeks and inside the ears. There is also a bikerole type that is rare that presents only black or tan color, always limited to the head and ears ”. Occasionally, a Chilean fox terrier is born in an alternate color, such as solid black. Such dogs are disqualified in the show ring and should not be bred but otherwise make as excellent companions or Working Dogs as members of another breed.

Usually, it happens around day 14. In this period the bitch’s discharge changes for distinctive red and reaching its end. The vulva gets back to average, and she will no longer allow mating.
