As dog owners, we are always on the lookout for a furry friend who brings joy, energy, and companionship into our lives. If you’re searching for a dog that embodies these qualities, look no further than Hava-jack. This delightful breed is a mix between the Havanese and the Jack Russell Terrier, resulting in a small, yet spirited companion that will surely steal your heart. In this article, we will explore the appearance, history, temperament, health, exercise, training, grooming, and nutrition of the Hava-jack, providing you with the information you need to make an informed decision about bringing one of these lovable dogs into your home.


With their adorable looks and charming personalities, Hava-jacks are a sight to behold. These dogs typically have a small to medium-sized frame, standing between 10 to 15 inches tall at the shoulder and weighing anywhere from 10 to 20 pounds. They have a sturdy build with well-developed muscles, giving them a compact yet athletic appearance.

The Hava-jack’s coat is another distinguishing feature. They often have a dense, silky, and wavy or curly coat that can come in a variety of colors, including white, cream, black, brown, or a combination of these shades. Their expressive eyes, which can be dark brown or hazel, are full of intelligence and curiosity. Additionally, their small, button-like nose and floppy ears add to their endearing appearance.

When it comes to grooming, the Hava-jack’s coat requires regular brushing to prevent matting and tangling. They may also need occasional professional grooming to keep their coat looking its best. Regular dental care, nail trimming, and ear cleaning are also essential to maintain their overall health and appearance.


The Hava-jack is a relatively new designer breed, combining the ancestry of the Havanese and the Jack Russell Terrier. The Havanese, originating from Cuba, is an ancient breed known for its affectionate nature and lively personality. They were often kept as companions for Cuban aristocrats and were even considered a national treasure. On the other hand, the Jack Russell Terrier, hailing from England, is a spirited and fearless breed originally developed for hunting small game.

By combining the traits of these two breeds, the Hava-jack showcases the best of both worlds. Their lineage brings together the playfulness and affection of the Havanese with the intelligence and energy of the Jack Russell Terrier, resulting in a well-rounded and adaptable companion.

Although the Hava-jack is not recognized by major kennel clubs as a purebred, their popularity has been on the rise due to their charming personality and lovable nature. They have become a favorite choice for families and individuals looking for a small yet lively dog that can fit well into various lifestyles.


When it comes to temperament, the Hava-jack is a true delight. They are known for their friendly and sociable nature, making them excellent family pets and companions for individuals of all ages. These dogs thrive on human interaction and are quick to form strong bonds with their owners.

The Hava-jack’s intelligence and eagerness to please make them highly trainable. They are known to pick up commands quickly and excel in various dog sports and activities. However, it’s important to remember that their Jack Russell Terrier heritage may also bring a touch of stubbornness. Patience, consistency, and positive reinforcement training methods are key to bringing out the best in these intelligent and spirited dogs.

Due to their lively and energetic nature, the Hava-jack requires plenty of mental and physical stimulation to stay happy and well-behaved. They enjoy interactive playtime, walks, and engaging toys that challenge their intelligence. Regular exercise is crucial to prevent boredom and destructive behavior. Additionally, early socialization is important to ensure they grow up to be confident and well-adjusted dogs.


As with any breed, the Hava-jack can be prone to certain health issues. However, by understanding these potential concerns and proactively managing their health, you can ensure your Hava-jack lives a long and happy life.

One common health issue seen in Hava-jacks is dental problems. Like their Havanese ancestors, they can be prone to dental diseases such as gum infections and tooth loss. Regular dental care, including brushing their teeth and providing dental chews, can help maintain their oral health.

Another health concern to be aware of is patellar luxation, a condition where the kneecap slips out of place. This can cause pain and lameness in the affected leg. Regular vet check-ups and monitoring your Hava-jack’s mobility can help detect and manage this condition if it arises.

Additionally, like many small breeds, Hava-jacks may be prone to allergies. These can manifest as skin irritations, itching, and gastrointestinal issues. Working closely with your veterinarian to identify and manage any allergies is crucial to keeping your Hava-jack comfortable and healthy.


Despite their small size, Hava-jacks have a surprising amount of energy. They require regular exercise to keep them physically and mentally stimulated. A daily walk or two, along with playtime in a securely fenced yard, can help fulfill their exercise needs.

Interactive toys and puzzle games are also excellent ways to provide mental stimulation for your Hava-jack. These activities tap into their intelligence and problem-solving skills, keeping them entertained and preventing boredom-related behaviors.

Remember that Hava-jacks are adaptable and can adjust to various living situations. They can thrive in apartments as long as they receive adequate exercise and mental stimulation. However, it’s important to note that they are not well-suited for a sedentary lifestyle.


Training a Hava-jack can be a rewarding experience. Their intelligence and eagerness to please make them fast learners. However, their Jack Russell Terrier heritage may also bring some stubbornness to the table. With the right approach and consistent training methods, you can bring out the best in your Hava-jack.

Positive reinforcement training techniques work best with Hava-jacks. They respond well to praise, treats, and rewards, making training sessions enjoyable for both you and your furry friend. Consistency, patience, and a firm yet gentle approach are key to successful training.

Focus on basic obedience commands such as sit, stay, come, and leash training. Once your Hava-jack has mastered the basics, you can move on to more advanced tricks and activities. Remember to keep training sessions short and fun, as Hava-jacks can have a short attention span.


Grooming a Hava-jack is a relatively low-maintenance task. Their coat requires regular brushing to prevent matting, especially if they have a longer, wavy coat. Brushing once or twice a week should suffice for most Hava-jacks. However, if your dog has a shorter coat, brushing once a month may be enough.

Regular bathing is essential to keep their coat clean and healthy. Aim for a bath once every six to eight weeks, or as needed. Pay attention to their ears and clean them regularly to prevent infections. Additionally, trim their nails regularly to keep them at a comfortable length.

Lastly, dental care is crucial for maintaining your Hava-jack’s oral health. Brush their teeth regularly using a dog-friendly toothpaste and provide dental chews or toys to help keep their teeth clean and strong.


Providing your Hava-jack with a balanced and nutritious diet is essential to their overall health and well-being. High-quality commercial dog food that is appropriate for their age, size, and activity level is recommended.

Consult with your veterinarian to determine the appropriate portion sizes and feeding schedule for your Hava-jack. Factors such as their age, weight, and activity level will influence their dietary needs. It’s important to monitor their weight to prevent obesity, as excess weight can lead to various health issues.

Additionally, treats can be used sparingly as rewards during training sessions or as occasional indulgences. However, be mindful of the calorie content of treats and adjust their regular meals accordingly to maintain a healthy weight.


The Hava-jack is a delightful and lovable companion for dog owners looking for a small yet spirited dog. Their playful and friendly nature, combined with their intelligence and adaptability, make them a great addition to various lifestyles. While they do require regular exercise, grooming, and training, the joy and companionship they bring to our lives are well worth the effort. So, if you’re ready for a furry friend who will brighten your days with endless energy and affection, consider welcoming a Hava-jack into your home.
