Just when you think a Jack Russell can’t get any cuter.

The Jack Chi is a mix between two dog breeds, the Jack Russell Terrier and the Chihuahua. These fur babies are often referred to as Jackahuahuas or Jack Chis, and they have inherited all the best qualities from both breeds.

Join me as I take a look at these sweet and adorable pups.

The Jack Chi was the result of a successful mating between Jack Russell Terriers and Chihuahuas in the 70s. It is not clear who owned the litter, but the breeder was seeking to create a small-sized designer dog with lots of energy who can be a great companion and fit in with the hustle and bustle of modeling living.

The Jack Chi stands at 12 to 15.5 inches and weighs between 8 and 18 pounds depending on the parentage.  The Jack Russell Terrier contributed the bulk to its build with a muscular but compact body and longer legs. The Chihuahua contributed to the smaller size of this dog.

The lively Jack Chi has an appealing personality which makes it a wonderful companion for its keeper as well as other household pets. It is playful yet affectionate with its owner to whom they will often offer their loyalty and devotion.

It is active indoors and outdoors but may bark excessively if left alone for long, which is the norm for Jack Russells.

The Jack Chi requires regular grooming with a soft slicker brush to prevent mats from growing. A diet of animal proteins, such as chicken and beef is recommended by most owners to avoid food allergies.

Children And Other Pets

The Jack Chi is great with children as it is gentle and loyal. They can play for hours without fear of developing any aggression. They also get along well with dogs that they have been raised in the same house with.

However, they may not be the best choice for households where there are multiple dogs because of their small size.

The Jack Chi has a life expectancy of about 15-17 years, and it is relatively healthy compared to other breeds in its category. Hip dysplasia can be a problem in this breed which can be detected in puppies younger than 6 months old by checking the hip joint for looseness or rotation.

They are also prone to eye problems such as cataracts and progressive retinal atrophy, but this can be prevented with proper care. The Jack Chi is also sensitive to anesthesia which makes it important for them to have physical assessments before surgical procedures.


The Jack Chi can thrive in an apartment as long as it gets regular playtime and walks. Their size makes them a great companion for families with children, but may not be ideal for households with many pets.

However, a yard is also recommended for the Jack Chi so that they can enjoy the great outdoors and expend their energy.


This breed is intelligent but requires a gentle hand and positive reinforcement when training. The Jack Chi can be stubborn at times so owners should remain patient during the training process.

They are highly observant which makes them easy to train, however, punishment is not recommended as it will have the opposite effect on their temperament. Owners must establish trust early on as they are known to bond closely with one or two people within their household.

They also love to fetch toy balls and frisbees which make them popular dogs for competitions.
