Jack Chi:Dog Breed Profile

Also known as Jackahuahua or Jackhuahua, Jack Chi is a cross between Chihuahua and Jack Russell Terrier dogs. These adorable dogs are energetic, intelligent, and extremely friendly. They are a mixed dog breed of two purebreds, and thus, their appearance is sometimes unpredictable. Some puppies look like Chihuahuas, while others may derive their features from Jack Russell Terrier.

Like Chihuahuas, Jack Chi dogs are small and perfect for people who like to adopt mini dogs. They are undeniably affectionate, and when appropriately trained, they quickly adapt to the surroundings. However, these dogs can be quite stubborn, so you'll have to remain patient while training them.

Jack is a breed of fun-loving dogs, and thus they easily bond with people in your family. Also, rather than attacking the strangers, these dogs become friends quickly. These dogs occasionally bark, so if you are looking for a quiet and friendly pup, this one is an excellent choice. Even though Jack Chi is a designer breed, you can find them in shelters and local rescue groups.

Jack Chis are considered healthy dogs. However, these dogs are susceptible to skin allergies, and thus, it is essential to visit the vet regularly. Here are some of the common health problems Jack Chis suffer from:

Patellar Luxation

Patellar Luxation is a common orthopedic disease where the kneecap of the dogs becomes dislocated. This condition generally develops after 4 months of age. Around 23% of Jack Chi has this condition, and thus, it is a hereditary issue. Its symptoms are limping, abnormal gait, and pain.

Treatment

The treatment of patellar luxation includes massaging the kneecap into place, surgery, or using braces.

Heart Problems

Jack Chis generally suffer from heart valve problems, mitral valve disease, and patent ductus arteriosus or PDA. In PDA, a small vessel in the heart doesn't close, and if the seriousness of the defect is high, it can lead to congenital heart failure. On the other hand, mitral valve disease occurs in mature dogs and is caused due to weakened heart valves. The valves that allow blood to flow backward in the heart are weakened, which causes strain on the heart.

Treatment

PDA can be repaired with heart surgery while mitral valve disease is managed with medication and also with exercise and dietary restrictions.

Hypoglycemia

When some fluids build up in the skull, it can lead to hypoglycemia. The build-up puts a strain on the brain and can also lead to spastic gait, seizures, or decreased mental functioning.

Treatment

Treatment of this condition includes medication or surgery

Tracheal Collapse

When the rings of cartilage are improperly formed or weak, it may lead to tracheal collapse. Signs of this condition are difficulty breathing and coughing.

Treatment

Mild cases are treated with medication, and for severe cases, surgery is needed.


Jack Chis try to be the pack leader, and thus, it is important to remain calm and consistent while training them. Always use positive reinforcement and techniques to encourage these dogs and show them that you are in charge. Most of the time, they respond well to the training, but sometimes, they may show stubbornness.

If you find it overwhelming to train these dogs, you can get them professionally trained. Also, remember that these dogs see smaller animals and pets as prey and, thus, might show aggression. So to train them well, start with early socialization.


Jack Chis are extraordinarily energetic, and regular exercise is needed for them to remain healthy. To reduce the risk of obesity and various other health issues, it is important to take the dog on a couple of long walks, jogging sessions, or arrange a scheduled playtime. As their parents are hunters, these dogs also love getting engaged in hunting activities.

You can play hide and seek, various ball games and use toys to make them feel satisfied. It is also essential to maintain a regular care routine for these dogs and visit the veterinarian to keep your dog healthy. A regular exercise schedule and check-up routine will keep these little creatures healthy.
