Like most designer dog breeds, the Jack Chi will inherit different physical characteristics from each parent breed. As both parent breeds are short, you can expect your Jack Chi to stand under 12 inches tall. As the Jack Russell Terrier weighs slightly more than your average Chihuahua, your Jack Russell Chihuahua mix will likely be on the heavier side.

In terms of their facial features, you can expect your Chihuahua Jack Russell Terrier mix to have a wedge-shaped head and black button nose of the Chihuahua. Your Jack Russell Chihuahua mix will have a short coat, but may either inherit the wiry coat of the Jack Russell Terrier, or the smooth, dense coat of the Chihuahua.

You can expect your Jack Chi to have muscular hind legs and a slightly longer body than your average Chihuahua, with a long tail that is either curled or straight.

As with most mixed-breed dogs, a Jack Chis physical appearance can be difficult to predict accurately, as it depends largely on which parent breed has the predominant gene.

The History of the Chihuahua Jack Russell Mix

The Jack Chi was a creation of post-war England when Jack Russell Terriers were bred with Chihuahuas in England to preserve the breed’s popularity. However, most of these crosses petered out by the beginning of the 80s. In an American context, as with most designer dog breeds, including many Chihuahua and Jack Russell mixes, it was likely created during the 1990s when crossbreeding became popular in the United States.

Fortunately, we know plenty about the history of each of their parent breeds – these small-sized breeds are known for their activity levels, strong prey drives, boundless energy and loyal and affectionate nature. Both the Jack Russell Terrier and the Chihuahua are highly intelligent dogs, so it’s likely that the breeders wanted to meld the Jack Russell’s terrier-type nature with the Chihuahua’s affectionate loyalty.

To learn more about the Jack Chi’s history, we’ll explore the history of each parent breed.

The History of the Jack Russell

The History of the Jack Russell

The Jack Russell Terrier was originally bred in England in the late 18th century by the Reverend John Russell, a parson was an ordained Christian responsible for a parish. Who sought a dog to bring with him on his hunts for the purpose of bolting foxes from their burrows. This led John Russell to a dog named Trump. Trump was everything that Parson John Russell had been looking for: a muscular body, an active nature and a fierce terrier.

One of the many things that Jack Russells are known for is their even-tempered aggression. Parson John Russell Terriers, as they were otherwise known historically, had huge amounts of energy and could run and execute their jobs as hunting dogs for bolting foxes, but also lose that aggressive streak when it came time for the hunt to end.

They quickly became popular throughout England and following the end of the Second World War, were one of the most common dogs among the English canine population, although they were crossbred with Welsh Corgis, Chihuhauas and other terriers – these became known as Russell Terriers.

The Jack Russell was a hardy breed that was commonly a companion pet when it was exported to the United States in the late 1970s by a Jack Russell enthusiast from England. Although, it struggled to be categorized by the American Kennel Club as a ‘toy breed’. Eventually, the AKC changed the breed standard (to a slightly smaller size) and name to the Parson Russell Terrier.

How Popular Are Jack Russells in the United States?

Since their arrival in the United States in the 1970s, Parson Russell Terriers (Jack Russell Terriers) haven’t really caught on like I’m sure Alisa Crawford (their importer) hoped they would.

In 2021, the Parson Russell Terrier, as the AKC recognizes them, ranked as the 117th most popular dog in the United States.

Who Are Jack Russells a Good Dog For?

Given their small size, one might think that Jack Russells are a good fit for almost anyone! And while this can be true, one has to bear in mind that the Jack Russell is a very energetic breed. They have massive personalities and require plenty of exercise.

For this reason, Jack Russell’s aren’t recommended for those who live in apartments, or for those who aren’t able to keep up with their exercise requirements – daily walks and off-leash time included. They’re not recommended for first-time dog owners, or those with smaller animals, as their high prey drive may cause them to accidentally kill your rodent or other small pet.

They’re best-suited to farms, or family homes with a house & yard that they can roam and run in. Although, don’t be surprised if they start digging up the yard, as their genes predicate them to run in fox holes.

How Did Jack Russells Come About?

The Jack Russell Terrier was first bred in the late 18th century in England from Trump, a small white and brown terrier, purchased by Reverend John Russell, who was seeking a capable fox-hunting companion.

Russell then bred Trump with other white terriers to create the modern-day Jack Russell Terrier. Over the years, Jack Russell’s physical appearance and outgoing nature haven’t changed much, although it has become more popular as a companion pet than a hunting dog.

When Did We First Cross-Breed The Jack Russell?

The earliest records of crossbreeding of the Jack Russell indicate that they were initially crossbred with Welsh Corgis, Chihuahuas and other small dogs at the end of the Second World War, in an attempt to revitalize the breed’s popularity following the decline of fox hunting in popularity.

In the United States, the Jack Russell became a popular family pet and several Jack Russell mixes were created by designer breeders in the 1990s and early 2000s. These included:

The History of the Chihuahua

The History of the Chihuahua

The Chihuahua is a fairly modern breed with an ancient history – stretching back to the Toltec Peoples, an Aztec tribe that inhabited modern-day Mexico in the 9th century, bred a small, mute dog known as the Techichi. It’s from this small animal that the Chihuahua is thought to have been bred over the centuries.

The modern-day Chihuahua was first noted in the mid-19th century in the Mexican state of the same name, when American tourists bought (or traded) their goods for this small little dog with a shrill bark. Standing less than 10 inches tall, the Chihuahua has always been a very popular companion pet – but their bark means they double as a guard dog!

Brought to the United States properly by the end of the 19th century and recognized by the American Kennel Club in 1904, the Chihuahua has long been a hit among American families and the elderly population.

How Popular Are Chihuahuas in the United States?

Chihuahuas are one of America’s most popular toy dog breeds! In 2021, they ranked as the 37th most popular dog in the United States, according to the American Kennel Club.

Who Are Chihuahuas a Good Dog For?

Because of their small size, Chihuahuas are well-suited for apartment living, and are popular among the elderly population. They are best described as spunky little dogs with high energy levels. Their fierce loyalty to their owners makes them fantastic guard dogs although they can develop a Napoleon complex.

Despite their size being conducive to apartment life, it’s worth noting that Chihuahuas suffer from separation anxiety, which can lead to destructive behaviors – if you notice that your Chi is starting to exhibit these behaviors, consider finding something to keep them occupied during the day.

How Did Chihuahuas Come About?

The exact origin of Chihuahuas is largely unknown. Although they descend from the ancient Techichi, a small, mute dog kept by the Aztec tribe known as the Toltec Peoples, who inhabited modern-day Mexico in the 9th century.

Since then, the history of Chihuahuas is made of much guess work until the mid-19th century, when they made their way across the border into the United States by being sold or traded with American tourists by their Mexican owners. In 1904, the Chihuahua was recognized by the American Kennel Club.

When Did We First Cross-Breed The Chihuahua?

The Chihuahua has fast become one of the most popular crossbreeds in the mixed-dog community – likely for their spunky personality and excitable nature – adding a little zest and joie-de-vivre to otherwise even-tempered dogs.

This has spawned a number of popular Chihuahua crossbreeds, likely beginning in the 1990s and early 2000s. These include:

How Important Is a Dog’s Temperament to Your Family?

A dog’s temperament is typically affected (to varying degrees) by two things: genetics and lived experience. Some dogs are predisposed to certain temperaments by virtue of their genes – for example, a Siberian Husky is likely to be a very active breed, as is their genetic makeup. However, a terrier that’s been abused or abandoned is likely to develop aggressive tendencies as a protection mechanism, or separation anxiety in the case of abandonment.

In the case of genetics, you can do research to find out what your dog is likely to be like temperamentally. Are they going to be rowdy and raucous? Like the ever-energetic Golden Retriever. Or, more laid-back and laissez-faire? Like the Pug. To some extent, these temperamental traits are hard-wired – you can adjust them with training, but it’s unlikely you’ll extinguish them entirely.

In the case of lived experience, this is something you talk over with a breeder or whomever you’re adopting your pup from. Lived experience take longer to adjust, if an adjustment is necessary, but can also be done – if you find that certain things about your dog’s temperament aren’t jiving with your family unit.

Knowing certain parts of a dog’s temperament beforehand can really better prepare you for taking ownership of this new animal, and can even reduce the amount of time and money you’ll spend training your new pup.
