The Jack-Chi dog is a mixture of two purebred dogs, the Chihuahua and Jack Russel. These dogs originated in the southern region of China around the year 1892. Jack-Chi dogs were designed for hunting, as their small, muscular body could dig underground and gather foxes and rats.

The Different Types of Mixed Breeds of the Jack-Chi

There are no known mix breeds of the Jack-Chi dog, as this is already a hybrid mix bred from the Jack Russel and Chihuahua.

Pros and Cons of Owning a Jack-Chi Dog

These little tricksters can get out of many places, so keep a close eye on them.

Extremely affectionate: Jack-Chis enjoy human companionship as they thrive on getting lots of cuddles and attention.High energy: Their energetic nature can be overwhelming to some people.

The Best Dog Food for the Jack-Chi Dog

Since the Jack-Chi is a small, bodied dog, they don’t need to consume much food. However, in accordance with their feeding chart, the Jack-Chi requires a proportionate one to two cups of dog food which should make up at least 500 to 560 calories per day.

The Jack-Chi enjoys a tasty treat, especially from table scraps. Therefore, be mindful of what you give this dog, as it can quickly gain weight.

Their diets should consist of protein, carbohydrates, healthy fats, vitamins, and minerals. An all-round balanced diet will provide them with a healthy, functioning metabolism, preventing Jack-Chi’s from experiencing food allergies where their stomachs can become inflamed, causing pain and discomfort.

A natural raw food diet should be given instead of processed dog food that consists of additives and chemicals, which can compromise the health of your dog’s gut and immune system. We recommend Canidae Grain-Free Pure Limited Ingredient Dry Dog Food.

Jack-Chi Dog Weight and Height

Both male and female dogs generally weigh between eight and 18 pounds and have a height of 14-15 inches.

Jack-Chi Health Issues

Because the Jack-Chi comes from two different parent breeds, this hybrid dog can inherit certain health conditions.

These health issues consist of:

Patellar Luxation

A luxating patella happens when the kneecap shifts out of its original position. If the kneecap is dislodged permanently or keeps moving automatically in and out of the aperture, your dog can experience severe pain, lameness, impaired mobility, or reduced limb function. Depending on the diagnosis, anti-inflammatory medication may help to control the pain.


If your dog is experiencing lethargy, sudden blindness, muscle loss, or weakening in the legs, hypoglycemia may at play. If your dog’s blood sugar keeps fluctuating, your veterinarian doctor will offer insulin injections, which will regulate it.

Heart Problems

If there is not enough blood being pumped throughout your dog’s body, your pet may experience lethargy, fainting, shortness of breath, reduced appetite, or swelling of the abdomen.

Legg-Calve-Perthes Disease

This condition results when the joint that connects to the ball-and-socket starts to degrade over time. Common symptoms include sudden lameness and pain.

Jack-Chi’s Temperament

These dogs are very smart, loving, and energetic. They are always looking for adventure, especially outdoors, as they search for birds and squirrels to chase. This breed longs for attention, so make sure to acknowledge your Jack-Chi when they are running up and down hallways, jumping on high to reach places, and just being silly. They have big hearts and love being close to their owners.

How to Take Care of a Jack-Chi Dog

Smaller dogs are becoming a lot more popular nowadays. Moreover, with the rise of a growing population, many more people are living in apartments, and the Jack-Chi is a perfect fit for a small home.

When owning this breed, it is necessary to provide them with a healthy diet, clean water, grooming, exercise, training, and regular vet visits. If your dog is well cared for, he can live a long and happy life.


The Jack-Chi has short fur, allowing the coat to shed moderately. You can brush your Jack-Chi a few times weekly to control shedding.

Because their coat is dense, they need a bath every two weeks to wash oil and lose hairs away, but keep in mind not to bathe them often as this can cause their skin to become irritated and dry.

Incorporate dental hygiene into their grooming routine, as this will keep their teeth healthy and prevent decay. Trimming your dog’s nails is also necessary, as this will allow them to walk correctly and stop their nails from curling or tearing, causing infection and discomfort.


Training will prevent behavioral issues and provide mental stimulation. A lot of consistency and patience is needed when training your Jack-Chi. They might be knowledgeable and respond well to commands, but they can also be headstrong, making training a bit more complicated.

Because they display these stubborn qualities, owners should be firm and show assertiveness. Make use of positive rewards, such as verbal praise or dog treats.


These dogs express a very untiring nature. They require a lot of exercise to prevent naughty behavior and stay healthy.

Your Jack-Chi will enjoy trips to the park and adventurous walks where they can explore and interact with other dogs and people. It is best to keep this breed on a lead, as they have a tendency to run off.


Jack-Chi puppies need to be supervised as they will be on the search for shoes and socks to chew on; pack away all personal items and give them a nice chew toy to occupy them.   

Jack-Chi Dog and Children

The Jack-Chi gets on very well with children making for a perfect friendship. Their silly nature and high energy will keep your child happy and entertained, but it is important to educate your child when bringing your bundle of joy home. Teach your child to be gentle and avoid pulling on their ears and tails. Even though these dogs are small, they will bite if their space is not respected.
