Jack Russell Chihuahua Mix- Jack Chi- A Complete Breed Guide

Combining Chihuahuas and Jack Russells results in Jack Chi, a vivacious, loyal dog with a high prey drive.  Jack Russell Chihuahua Mix, despite their small size, requires regular exercise to maintain his/her happiness. A hybrid Chihuahua-Jack Russell dog could be the ideal companion for you if you’re searching for a lively small dog to bring some energy into your life.

Jack-Chi History

The Chihuahua

It makes sense that chihuahuas are among the most well-liked dog breeds worldwide.

With their little stature, characteristically huge, pointed ears, and endearing disposition, they are simply charming. There are two varieties of Chihuahuas: long-coated and smooth-coated. The breed is indigenous to Mexico and is named after the state of Chihuahua.


Long-coated Chihuahuas have long, silky fur that can be curly or straight, and smooth-coated Chihuahuas have short, smooth fur.

The Jack Russel

The Jack Russell is a tiny, stocky dog that has black or brown markings on its white coat. Originally bred for hunting foxes and rats, Jack Russells are now frequently kept as pets.

Parson John Russell created the breed in England during the 1800s because he wanted a dog that was courageous enough to confront foxes and small enough to chase them into their burrows.

He started breeding terriers and hounds to do this, creating a dog that was both courageous and quick.

Even in this day and age, Jack Russells are still used as hunting dogs and have become well-liked pets. They are very sought-after pets because of their loving disposition, intelligence, and trainability.

The Jack Chi

An amalgam of the Chihuahua and the Jack Russell Terrier is the Jack Russell Chihuahua mix. Although the breed’s precise beginnings are uncertain, it is believed that the Jack Chi was initially produced in the US in the 1980s.

Popular breeds of dogs, Jack Chis are valued for their devotion and loyalty. But because of their intense prey drive and high activity levels, they frequently wind themselves in shelters.

The American Kennel Club (AKC) does not accept the hybrid or designer dog known as the Jack Russell Chihuahua mix.

Jack-Chi Appearance

Jack Russell and Chihuahua mix breeds are little dogs with short legs and a compact build.
They have round heads and upright ears.

These dogs have a black nose and big, dark eyes. They have a short coat that can be rough or smooth.

There are many different hues of Jack Russell Chihuahua mixes, such as black, white, brown, and tan.

A Jack Chi dog usually stands 12 to 15 inches long and weighs 8 to 18 pounds.

Jack-Chi Temperament

A Chihuahua Jack Russell mix’s disposition combines traits from each of its parent breeds.

Chihuahuas are energetic, passionate, and passionately loyal pets who love their families. They are also wary of strangers and vigilant.

Though they are loyal friends and proud members of the family, Jack Russells need more mental and physical stimulation than Chihuahuas do. They are brave, mischievous, and unyielding.

A Chihuahua Jack Russell mix’s disposition is probably a mix of these traits. While they may be lively and loving with their family, the mix is wary of strangers.

To avoid boredom or destructiveness, they will also require regular exercise and mental stimulation.

Jack-Chi Health

The lifespan of Jack Russell/Chihuahua mixes is between 13–15 years.
Although they are generally super healthy, they do inherit their parent breeds’ health issues.

We suggest that you talk to your dog’s breeder or vet about the health problems that your pet friends may be more likely to get.

Your dog’s owner will know about any health issues your puppy, whether it’s a mixed breed or not, might be prone to based on how healthy his or her parents are.

But if none of these work, you could also use a DNA test on the dog. I’ve used the Embark dog DNA test on my two dogs. I like that this DNA test for dogs can tell me what type they are and if they are healthy.

When the test results came back two weeks later, I was pleased to see that the breed ID results were very correct.

The health finding also helped me learn more about the health problems my two dogs are more likely to have and how I can better take care of them.

Skin Issues

It is well known that Jack Russell/Chihuahua mixes are prone to skin allergies. Itching is the most prevalent symptom, and it can cause redness, inflammation, and hair loss.

Allergens can originate from a variety of things, including chemicals, food, and pollen. It’s important to see a veterinarian if your Jack Chi dog scratches a lot to rule out any underlying issues.

Hip Dysplasia

Hip dysplasia, a disorder where the ball and socket of the pet’s hip joint don’t fit exactly right, is more common in Jack Russell/Chihuahua mixes.

Arthritis, discomfort, and lameness may result from this. To manage the illness and stop future harm, early identification and therapy are crucial. Hip dysplasia is usually diagnosed by X-ray, and surgery may be necessary to address the issue. Exercise and weight control may also be advised in specific circumstances.

Patellar Luxation

When the kneecap shifts out of place, it can lead to this disorder. Inherited patella may result from trauma, hereditary factors, or even ordinary wear and tear.

The illness manifests as pain, trouble walking and limping. A luxating patella may result in arthritis or other joint issues if treatment is not received. The illness is treated with rest, physical therapy, and occasionally surgery.

Jack Russel Chihuahua Mix Care

When all is said and done, a Jack Russell/Chihuahua mix is an excellent low-maintenance dog for those who don’t have the time or desire to provide the more involved kind of pet care.

Shedding Level

It’s common knowledge that Jack Russells and Chihuahuas are breeds that shed less.

As a result, the majority of Chihuahua Jack Russell Mixes are probably not heavy shedders. These mixed-breed dogs are also a good option for allergy sufferers because they typically inherit their hypoallergenic coat from their Chihuahua mom.

However, it’s crucial to remember that no dog can ever be hypoallergenic. Despite relatively little shedding, some people may still be allergic to these mixed-breed dogs.

Regretfully, it is hard to forecast a certain Jack Russell Chihuahua mix’s shedding behavior. Seeing how the dog sheds over time is the best method for figuring this out.


Mixes of Chihuahuas and Jack Russells have low coat maintenance because they don’t shed much.

This is because, unlike double-coated breeds, they only have one layer of fur, meaning they need less maintenance.

To prevent matting and tangles, it is crucial to routinely brush their fur.


Mixes of Chihuahua and Jack Russells are lively, playful dogs that need a balanced diet to keep in good health. There are a few important things to remember when feeding your Jack Chi.

  • Start with a scrumptious meal selection. This will guarantee that your Jack Chi receives all the vitamins and nutrients he requires.
  • Add some wet food to your Chihuahua Jack Russell mix’s diet; this will help them stay hydrated and healthy by providing much-needed moisture.
  • To reduce stomach discomfort and maintain consistent energy levels throughout the day, feed your Jack Russell/Chihuahua mix multiple modest meals as opposed to one or two large ones.
  • If your Jack Chi shows symptoms of stiffness or arthritis, ask your veterinarian about adding nutritional supplements to their food, such as omega-3 fatty acids, probiotics, prebiotics, or joint support supplements.


It takes time and care to train a Chihuahua/Jack Russell mix, but the rewards can be great.

The fact that every dog is unique and will learn at their rate is among the most crucial things to keep in mind. While some people might pick it up fast, others could require more practice and patience.

The secret is to never give up and to be consistent with your directions and rewards. You can quickly become an expert trainer of your Jack Russell/Chihuahua mix with a little perseverance and patience.


A unique breed of dog, Jack Russell Chihuahua hybrids were originally developed for hunting.

Because of this, Jack Chis need a lot of activity and has high energy levels. Insufficient physical activity might cause Jack Chis to become agitated and aggressive.

Because of this, it’s critical to guarantee that Jack Chis dogs have lots of chances to run and play. Exercise is essential, and a smart way to give it to your dog is to walk or run every day. Many dog owners also opt to enroll their pets in agility lessons or other activities.

Recall that exercising doesn’t only have to involve going for a walk; it can also involve playing catch, frolicking in the yard, or simply taking a slow walk around the block.
