The Jackhuahua, or Jack Chi, is a crossbreed dog. Also known as a designer dog, it has many fantastic qualities!

The Jack Russell - Chihuahua mix may be adorable, but as with any dog, you need to make sure their personalities fit in well with your lifestyle. So here's everything you need to know about this terrier mix!

What is a cross between a Jack Russell and a Chihuahua?

These two breeds are very different, and putting them together makes for a pooch calmer than the Jack Russell, but more active than the Chihuahua. Here's a summary of what you need to know about the parent breeds:

The Jack Russell Terrier

Originally a fox-hunting breed from the UK, Jack Russells are small dogs belonging to the Terrier group. Despite their size (10 to 15 inches at the shoulder, and weighing in at 13 to 17 pounds), they are high energy dogs, known for their speed and endurance. Strong-willed and fiercely independent, they are certainly not lap dogs! They need at least 1 hour of exercise every day to stay happy! Training is also extremely important for this breed, in order to avoid destructive behaviour in the home. They are very intelligent, but are free-thinkers, so they are best for experienced trainers. They are a healthy breed which comes in two coat varieties: the smooth and rough, both of which are easy to groom.

The Chihuahua

Originating from Mexico, Chihuahuas are one of the most popular lap dog breeds and it's no wonder why: from 6 to 9 inches in height and 3 to 6 pounds only in weight, these dogs love nothing more than spending time with their humans. If adopted into a family, Chihuahuas tend to do better with older children rather than small children. They often bond very closely to one member of the family, and can become very protective of that person. It is therefore very important to train and socialise this dog from a very young age: they are not aware of their small size, and can put themselves in dangerous situations if they are not careful! They are not all-weather dogs, and even the long-haired varieties will need to wear a coat in colder weather.

What is a Jack Russell cross Chihuahua called?

History of the Jack Russell Chihuahua cross

Filled with boundless energy, requiring mental stimulation and plenty of exercise, the Jack Chi is a bundle of fun. A very friendly dog, it will certainly enjoy lots of snuggles with its new owner. This is a new hybrid 'breed', otherwise known as a 'designer dog', so it is not recognised by any kennel clubs. The crossbreed originated in the US around 40 years ago, perhaps as a happy accident!

Physical characteristics of the Jack Chi

The Jack Chi dog has a Jack Russell’s triangular head, long muscular body, and a short neck as well as the rounded eyes of the Chihuahua. The ears can be floppy and folded, similar to a Jack Russell's, or erect and pointed like the Chihuahua's. The snout is long, and slightly thinner than that of a Jack Russell's. The hindquarters are muscular and strong, the legs are short and the long tail is usually curled.

Height Size: 14 - 15 inches

Weight: 8 – 18 lbs

Coat colours: Black, chocolate, fawn, golden, cream, and white. Can be a solid colour, or a mix of two or three colours!

What is the temperament of a Jack Chi?

Sweet-tempered and very lively, Jack Chis need an abundance of daily exercise. The Jack Russell Terrier character shows through as always wanting to be the leader. This results in them being rather headstrong and more difficult to train. These dogs are known to be chewers, so ensure that your pup has a good supply of chewable toys, if you don’t want to end up with damaged furniture or shoes. They are very sociable dogs that get on well with older children and other pets. Friendly and affectionate, they love lots of attention and cuddles. Just like the Chihuahua, they can sometimes suffer from separation anxiety, so make sure you teach them how to be independent from a young age.

Are Jack Chis aggressive?

The Jack Chi is energetic, intelligent and sociable. They do love to play with other dogs and children, however, if the playtime gets rough or their tail and ears are pulled, they can get a little bit snappy. If you socialise your Jack Russell cross Chihuahua early, however, they should never be aggressive. Of course, because it is a mixed breed, you can never be certain what personality trait your Jack Chi will inherit from its parents, and this can play a part on how the dog interacts with other pets and humans.

Exercise needs of the Jack Russell Chihuahua cross

These active little dogs appreciate lots of exercise. They will often follow their noses and chase after birds or balls. They have inbuilt preying instincts and certainly love running around for hours off the lead. The Jack Chi isn’t very tolerant of cold weather, so make sure you have a coat for them in the winter.

Grooming the Jack Russell Chihuahua cross

This short-haired dog doesn’t require intense maintenance and grooming. A weekly brush should suffice to keep shedding at a minimum. Only bathe them when absolutely necessary, in order to maintain the natural oils in the fur. Wipe the dog’s ears once weekly to keep them clean, and brush teeth daily.

Feeding the Chihuahua Jack Russell mix

These dogs are sometimes fussy, picky eaters but in the main, happy to eat whatever you feed them. Take care not to overfeed them, as they are guzzlers and don’t know when to stop eating.

Health problems of the Jack Chi

This is quite a hardy breed of dog although it is prone to similar health problems to their parents. Above all, there is a possibility of sensitive skin, especially when it comes to reactions to insect bites and fleas. Some Jack Russell Chihuahua dogs present as having several allergies, especially to fresh cut grass and soy. Jack Russells are noted for several eye diseases, like glaucoma, and also ear infections and deafness.
