History of the Jack Russell Chihuahua Mix
The Jack Chi is a new hybrid like many designer dogs, so there’s not a lot of historical information available on them. They probably originated in the United States in the 1980s or 1990s. It was a time when crossbreeding regained popularity and many designer dogs appeared on the scene.
The Jack Russell Terrier was developed in England specifically for fox hunting in the early 1800s. These dogs are originally from the Fox Terrier group. A sturdy, compact body, strong legs, and small chest allowed them to follow their prey into the foxholes and move underground. They were also used for vermin control and have a very strong tendency to dig. They were named in honor of Reverend Jack Russell. He was the hunting enthusiast believed to have bred two different types of terriers together to create this particular breed of terrier.
The tiny Chihuahua is one of the oldest breeds in the Americas with a lineage that extends back to pre-Columbian times. They appeared to be the favored companion of the Aztecs. And they are believed to have originally descended from the Techichi breed. The Techichi is a somewhat larger breed that was domesticated by the Toltec people. The Chihuahua came to America in the mid-1800s.
Jack Chi Appearance
The appearance of Jack Chi puppies can vary greatly depending on the characteristics they inherit from the parents like any mixed breed. Common physical features of this mix breed are a short neck and a long, muscular body. They tend to have the large round eyes of a Chihuahua set into the triangular head of the Jack Russell.
Ears can either be pointy and erect like the Chihuahua’s or folded and floppy like the Jack Russell parent. The snout is usually long but could be thinner than a Jack Russell. Their hindquarters are strong and muscular, yet the shorter leg length and long, curled tail resemble the Chihuahua.
How Big Are Jack Chi Dogs?
Jack Chi dogs tend to stand at about 10 to 15 inches in height and range from 8 to 18 pounds.
Jack Chi Colors
Their coat is typically short and dense, and their coloring widely varies. Jack Chis can be black, white, brown, chocolate, cream, golden, or fawn colored.
Their coat can be bicolored as well. The most common combinations include the following: black and brown, black and white, black and tan, brown and white, dark brown and light brown.
You can even find tricolored Jack Chis!
Jack Russell Terrier Chihuahua Mix Grooming
A Jack Russell Terrier Chihuahua Mixes’ short, dense coat means minimal shedding and maintenance. Brushing them once or twice a week with a hard-bristled brush should be enough to keep their coat smooth and healthy.
You should check your Jack Chi’s ears for signs of infection and clean them carefully each week. As with all breeds, keep their teeth clean by brushing them with dog toothpaste at least twice a week. It is recommended that you start these grooming habits early with your pup so they become accepting and tolerant of them.
Are Jack Chis Hypoallergenic?
Despite their usually short coat, the Jack Chi is a fairly high shedding dog. They are not a low shedding breed, and unfortunately are not hypoallergenic.
Jack Russell Chihuahua Mix Temperament
The Jack Chi is a tenacious, intelligent, and lively dog. Likewise, with their appearance, you never know which traits your pup will inherit. The Chihuahua side may help balance out some of that Jack Russell exuberance, but don’t bank on that. Be prepared for a high energy companion that loves having a job to do.
Jack Chis are loyal and devoted dogs that enjoy spending time with their owners. They are also a breed prone to separation anxiety and can become quite vocal or even destructive if left alone too long.
While they are generally friendly and playful dogs, Jack Russell Terrier Chihuahua Mixes can become intolerant of rough play or tail and ear pulling. They are not known to be very aggressive, but they can get snappy if they get annoyed.
They should get along with other dogs well if socialized early. But you can’t be certain what characteristics your Jack Russell and Chihuahua Mix will inherit from its parents in how it interacts with other small pets.
For instance, the Jack Russell was used as a hunting dog and still retains those instincts. Consequently, they don’t generally do well with cats, because they view them as prey.
Jack Chi Training
Training your Jack Chi will take patience and perseverance. It’s recommended to start right from the day they come home with you. Waiting can lead to a more strong-willed pup.
The Jack Russell’s side naturally wants to be the leader of the pack and paired with the Chihuahua’s stubbornness this breed is not the easiest to train using traditional methods. But fortunately positive reinforcement doesn’t put you into conflict with your dog. Reinforce and reward behaviors you want to see, and they’ll be delighted to work with you.
They are intelligent dogs and can become bored quickly. Keep training short and varied without too much repetition. It’s in the Jack Chi’s nature to smell, and they will often follow their nose, which is why it is best to start recall training at an early age. It is also in their nature to dig, so teach them the difference between the backyard and the living room sofa.
Early socialization is key to eliminate any signs of aggression and to ensure your furry friend will play nice with other dogs and humans alike.
Jack Chi Exercise
These playful pups require plenty of daily exercises to stay happy and out of trouble. They will need plenty of play time in addition to going on long walks a couple of times a day. Fetch in the dog park or running loose in a fenced yard will help burn off some of that boundless energy and discourage bad behavior.
Both parent breeds are adept at canine sports, especially the Jack Russell. This can be a great way to exercise your Jack Chi’s body and mind. They also make great hiking companions for active individuals or families.
On the other hand, keep in mind that the Chihuahua side of your mix may not handle the cold well. The Chihuahua has trouble warming themselves up effectively once they are cold. Therefore, dog clothing for cold weather may be necessary for outdoor exercise.
Jack Russell Chihuahua Mix Health
The Jack Chi’s health is mostly dependent upon the health of the two parent breeds. While your dog could inherit health issues found in either breed, they are most likely to inherit the ones common to both parents.
Most of the health concerns associated with Chihuahuas stem from their diminutive size. They are at an increased risk for dystocia which means they have trouble giving birth. Dental health is also a major concern as tooth crowding is almost inevitable and promotes tooth decay. To prevent periodontitis, brush their teeth with dog toothpaste at least twice a week.
A less serious, but common, health issue in Chihuahuas is allergies. This breed is prone to atopy, a kind of skin allergy that causes itchiness and affects the feet, ears, belly, and folds of the skin. Signs often include rubbing of the face, persistent licking, and chronic ear infections. See your veterinarian if you think your dog may be suffering from allergies.
Here are a few more serious health issues that can affect the Chihuahua:
- patellar luxation
- heart problems
- tracheal collapse
Jack Russell dogs are generally healthy, but there are a few conditions they are genetically predisposed to. They are prone to patellar luxation and atopy skin allergies, just like the Chihuahua. One minor health issue Jack Russell Terriers are prone to is ear infections. Check your dog’s ears regularly for redness, odor, or a brown or yellow discharge. Also, take notice if your dog is scratching their ear a lot.
The Jack Russell has a few other health concerns that could potentially affect your Jack Chi:
- eye problems
- legg-calve-perthes disease
- liver problems
- blood disorders
Jack Chi Lifespan
The lifespan of a Jack Chi generally falls in the range of 13 to 16 years.
The life expectancy of a mix breed dog tends to fall within the average parameters of the parent breeds. Fortunately, both the Chihuahua and the Jack Russell are quite long living breeds. The Chihuahua’s lifespan is about 14 to 16 years and the Jack Russell Terrier’s lifespan ranges from about 13 to 16 years.

Whatever the Jack Russell Chihuahua Mix price, it’s imperative that the breeder has tested their animals for genetic health issues that impact both the parent breeds and that they can provide you with these test results.
Recommended Testing For Chihuahuas

- Ophthalmological Exam
- Patella Evaluation
Recommended Testing For Jack Russell Terriers
- Late Onset Ataxia (LOA)
- Primary Lens Luxation (PLL)

Remember when you are looking at the Jack Russell Chihuahua price tag, you are paying for a designer dog. It comes with the peace of mind from using a responsible breeder.
