How many Jack Chi are there in the world?
Despite being a popular designer dog breed, the number of Jack Russell Chihuahua mix-breed dogs around isn't well documented. This is because the Jack Chi is considered to be a hybrid breed and is not recognized by the American Kennel Club and several other big canine organizations. The Jack Russell Chihuahua mix breed is, however, recognized by organizations like the Dog Registry of America, Inc. (DRA), American Canine Hybrid Club (ACHC), Designer Dogs Kennel Club (DDKC), as well as the International Designer Canine Registry (IDCR).
Where does a Jack Chi live?
These designer Jack Chi dogs typically live in a house with a family that has either adopted or bought them from a breeder.
What is a Jack Chi's habitat?
Since these dogs aren't purebred dogs but have been brought into existence as a result of people's demand to make them companion animals in the house, their habitat consists of the house that has adopted or bought them.
The origin of the parent breeds however can be traced back to that of Jack Russells as well as Chihuahuas. Bred in the 1800s in the United Kingdom, the Jack Russell Terrier was used as a hunting dog before they came to be regarded as the much-loved family pet. The Chihuahua's origin dates back to the Toltec people of Mexico as early as the ninth century. The Jack Chi however has come to be loved as a family dog for its affection, enthusiasm, and loyalty.
Who do Jack Chis live with?
The Chihuahua and Jack Russell Terrier mix lives in houses with people. Their friendly nature makes them good companions even in households where kids are present. If you have other dogs in the house, you will probably want to socialize your Jack Chi with them before letting them mingle as things could get a little complicated.
A Jack Chi isn't a good option for you if you already live in a home with cats because they don't get along well with cats. Just like the Jack Russell, they do have strong predatory instincts and can easily be the cause of stress for cats. The situation may be different if you bring home a Jack Chi puppy and socialize them with your cats early on, but to be safer, try to avoid bringing home Jack Chi puppies into houses that already have cats. You'll just be unnecessarily creating a stressful environment for everyone in the house.
How long does a Jack Chi live?
The average Jack Chi life span of these dogs is 13-18 years. A Jack Chi's health depends upon the health of the parent breeds. Some common health concerns of the Chihuahua breed and Jack Russell Terrier also prove to be causes of concern for Jack Chis.
There are some common health concerns you should be aware of as Jack Chis age. Patellar Luxation is one such condition affecting small dogs like Jack Chis and may be congenital or the result of an injury. It occurs as a result of the kneecaps getting dislocated, resulting in extreme pain. Eye problems are another cause of concern. Glaucoma, cataract, and lens luxation are issues to check for in Jack Chis.
Jack Chi puppies can also suffer from a condition called patent ductus arteriosus where a tiny heart vessel fails to close after birth. A Jack Chi full-grown dog can suffer from mitral valve disease, where blood puts a strain on the heart by flowing backward as a result of weakened heart valves. Low blood sugar levels are another health concern for Jack Chis as they age and this could affect the amount of exercise they get and their eating habits.
Thrombocytopenia and hemolytic anemia are the rare blood disorders that can affect Jack Chis as a result of Jack Russells being more likely to suffer from these conditions. Another condition to watch out for in Jack Chis is Tracheal Collapse, where cartilage rings of the trachea may not have formed properly or may have become weak, resulting in breathing difficulty and excessive coughing among Jack Chis.
Like the Jack Russell Terrier, Jack Chis are more prone to suffering from congenital deafness. The head shape of Jack Chis makes them more prone to a build-up of fluid in their skull, causing hydrocephalus. Apart from these issues, Jack Chis may be affected by a liver issue called portosystemic shunt, wherein an insufficient supply of blood reaches the liver, preventing it from effectively removing the body's toxins.
How do they reproduce?
Jack Chis reproduce in the same way that other mammals do. It is, however, not common to breed a male and female Jack Chi to get a Jack Chi puppy. Breeding is usually done using a female Jack Russell Terrier and a male Chihuahua so that the larger, muscular body of the Jack Russell can push out a bigger Jack Chi puppy. The small body of a Chihuahua would not be suited for this.
What is their conservation status?
Their conservation status is that of Least Concern because people continue to demand designer dogs as companion animals for their homes.

What do they eat?
While one parent breed may have its roots in hunting, Jack Chis are kept as pets and usually eat a diet of kibble or wet food, as advised by your veterinarian. They tend to be picky eaters and are likely to overeat if food is left out in plain view of them, so it is important to regulate what they eat and how often.
If you're giving your Jack Chi dry food for dogs, make sure it is premium high quality. Packaged dog food will meet the nutritional needs of your Jack Chi because it is formulated to contain the right percentage of meat-based protein, healthy fats, and carbs. You need to make sure you pick the right kibble based on the size, activity level, and age of your dog. You may also have to make certain special dietary changes if your Jack Chi suffers from health issues that warrant these changes.

Would they make a good pet?
Jack Chis make great pets and these fun-loving dogs are the perfect addition to your family. They have a sweet disposition and are extremely affectionate and fond of cuddles. If you have other dogs at home, you will need to socialize and train your Jack Chi first before introducing them to your other pets.
They also have a high level of energy so keeping them physically and mentally active is necessary. Training a Jack Chi isn't the easiest thing to do because they do tend to be stubborn. While they may not be easy to train, if you do manage this yourself or with the help of a trainer, you won't regret it.
Their short, dense coat also makes it easy to groom them without wasting a lot of time or money. Using a hard bristled brush on their coat once a week is all that is needed to maintain the health and condition of their coat. Jack Chis are also not fans of the cold weather so it's a good idea to keep some blankets or outfits ready to keep them warm - and if that doesn't work, you can always rely on cuddles to do the trick.
Did you know...
Ineffective Jack Chi training and socialization can lead to the development of spatial aggression and separation anxiety. Jack Chis aren't aggressive dogs, but if you annoy them, they can get snappy. They also don't respond well to rough play or pulling of the ears and tail.
The allergies and shedding that Jack Chis can cause are much lesser than that caused by other dog breeds. Whether or not they are hypoallergenic will depend on their coat type. Jack Chis with short, dense coats won't be a problem for people with allergies but those with longer coats may not be the best options for people with severe pet allergies.
Jack Chis are regarded as big chewers and not just when they're teething. The sweet, fun-loving Jack Chi temperament isn't going to seem so cute when you return home to see that your shoes, furniture, and other valued belongings have been chewed up. For this reason, it's important to give them plenty of chewable toys that they can chew on.
Jack Chis have a lot of energy and need to be exercised at least twice a day. Going for walks regularly will expose your dog to new sights and smells that will stimulate them mentally as well. Apart from walks, you should play games with them and take them on some of their favorite activities. These include playing frisbee, going to the dog park, going camping, swimming, and other activities.
