The Cojack is a unique dog breed that blends the energy levels from one of the most hyper dog breeds -the Jack Russell Terrier – with the Corgi.

As someone who has owned and raised a Jack Russell for the past 4 years, I feel as if I have enough background and experience to share what you can likely expect if you are considering adopting a Cojack.

The Cojack is a hybrid of two fantastic breeds, but for certain owners, it’s important to understand the behavior, temperament and even the background on both dog breeds.

Doing so will allow you to understand if the Cojack is the right Jack Russell mix breed for you and your family or just help you understand the dog breed in a more complete fashion.

Let’s dive into the details of both breeds and break down the important information you need to understand about the Cojack.

The Jack Russell Terrier and Corgi

If I had to pick two of the most distinct characteristics of the Jack Russell Terrier, I would 100% say prey drive and high energy.

That is what the Jack Russell Terrier is. A hunting dog with an extreme amount of energy along with dedication and loyalty towards owners and caretakers.

In 2023, Jack Russell Terriers are still commonly used as working dogs and make great companions for active families.

The Corgi, on the other hand, is more known as a herding dog compared to the hunting instincts of the Jack Russell Terrier.

It’s also important to note that you have two distinct types of Corgis.

The Cardigan and the Pembroke.

Both breeds are known for their short legs and long bodies, which allowed them to easily navigate herding duties assigned to them by their families and owners.

Today, Corgis are beloved family pets and have even become somewhat of an internet sensation.

It’s when you put the Jack Russell Terrier and Corgi together that you get one unique dog breed.

Let’s cover all the details about the mix breed specifically so you can understand items such as size, behavior and any unique characteristics or needs you may run into if you decide to adopt a Cojack in the immediate future.

The Size and Appearance of the Cojack

The Cojack is a small to medium-sized dog that can weigh anywhere from 15 to 30 pounds and stands about 10 to 15 inches tall at the shoulder.

This is relatively similar in size to my Jack Russell Terrier (Luna) is a 4 year old female JRT.

30lbs would resemble the extreme or larger end of the size scale while 15lbs can be more expected and common with the Cojack.

They have a short, dense coat that can come in a variety of colors, including black, white, brown, and brindle.

They often have the distinctive markings of a Corgi, including a white chest and legs, and the Jack Russell Terrier’s pointy ears.

Let’s talk about the best practices when it comes to grooming a Cojack next.

The Cojack’s coat is relatively low-maintenance and only requires brushing once or twice a week to keep it looking shiny and healthy.

A common mistake many dog owners make, including myself is overbathing.

Especially with a Jack Russell Terrier or a mixed breed of a Jack Russell Terrier.

With the low maintenance coats and the thin hair, it’s best to spread bathing out over 4-8 weeks to avoid irritating the skin.

I would also recommend regularly trimming the nails of your Cojack to prevent overgrowth, and their ears should be checked for any signs of infection.

Outside of these easy and minor grooming needs, a Cojack is an easy dog to care for when it comes to grooming.

Cost to Adopt

The cost of adopting a Cojack can vary depending on several factors, including the breeder, location, and demand.

Typically, you can expect to pay anywhere from $500 to $1,500 for a Cojack puppy.

When you search, I would personally compare options with several different breeders and ensure you are working with a breeder you trust.

Ask for documentation and see if you can have the opportunity to meet the parent dogs of the Cojack.

This can give you a better idea if this dog is a good fit for you and your family and for you to feel comfortable with the blood line and gene pool for your Cojack.

Exercise Needs and Energy Levels

Both the Jack Russell Terrier and the Corgi are high-energy breeds that require plenty of exercise and stimulation to stay healthy and happy.

It’s important to consider the exercise needs of both breeds when considering the Cojack mix.

If I had to give you any piece of advice to ensure you take from this discussion, it would 100% be to ensure you provide this mix breed with plenty of exercise and plenty of opportunities to burn off energy.

Jack Russell Terriers are known for their energy and athleticism.

In my opinion, a Cojack, due to being a mix with a Jack Russell Terrier will need at least an hour of exercise per day, including plenty of opportunities to run and play.

You can mix it up and choose the activities you prefer.

I personally will use any activities such as something as easy as chasing after balls and frisbees or even tagging along with you for a jog or a hike.

If you miss a day or two with a Cojack, it’s not the end of the world.

Try and pick a schedule and stay relatively consistent and you will be in great shape.

A tired dog is a happy dog, so providing plenty of opportunities for exercise and playtime is key to raising a healthy and happy Cojack.

Behavior and Temperament

Both Jack Russell Terriers and Corgis are known for their playful and energetic personalities, and the Cojack is no exception.

I can tell you from firsthand experience that these dogs are highly social and love spending time with their families.

If a Cojack is going to be anything like my Jack Russell Terrier, they will be loyal, affectionate, and always eager to please you.

They are also very intelligent, which can make them great at learning new tricks and commands.

While they are generally friendly and outgoing, Cojacks can sometimes exhibit a stubborn streak, particularly when it comes to training.

This is where their Jack Russell Terrier parentage comes in.

Jack Russells are known for being independent and strong-willed, and this trait can sometimes be passed down to their offspring.

It’s important to start training and socialization early, and to be consistent and patient with your Cojack. Positive reinforcement is always the best approach, as these dogs respond well to praise and rewards.

One of the unique features of the Corgi parent breed is their herding instinct. This can sometimes manifest in the Cojack as a tendency to nip at heels or try to herd small children or other pets.

While this behavior is generally harmless, it’s important to discourage it early on to prevent any potential injuries or accidents.

Despite these minor quirks, the Cojack is a wonderful family pet that is great with children and other animals.

They love to play and run around, and are always up for an adventure.

They are also very loyal and protective of their families, and will always be there to provide comfort and companionship. With proper training and socialization, the Cojack can make a wonderful addition to any home.


Luna (my Jack Russell Terrier) is by far one of the smartest dogs I’ve ever raised and ever had the pleasure to be around.

No doubt about it.

Both the Jack Russell Terrier and the Corgi are intelligent breeds, so it’s no surprise that the Cojack is also highly intelligent.

They are quick learners and thrive on mental stimulation.

This means that training and providing them with plenty of toys and puzzles to play with is essential for their well-being.

You will notice relatively quickly that pleasing you as the owner, participating in training routines or just playing will bring a Cojack the most joy out of about anything you can offer.

Hands down.

Is the Cojack a Good Family Pet?

I was skeptical at first as well before adopting my Jack Russell Terrier.

I was worried about the energy levels and the information I had found online about the Jack Russell Terrier prior to adopting my dog.

But here is my answer and I’m sticking to it.

Yes, the Cojack can make an excellent family pet, especially for active families who enjoy spending time outdoors.

They are affectionate, loyal, and highly trainable, making them great companions for first-time dog owners. However, their protective nature and tendency to bark at strangers or other animals may make them a better fit for families with older children.

It should be noted that the above statement only holds true if you are going to put in the time and effort to provide proper training and socialization.

Without training and socialization, a dog breed such as the Cojack can quickly become a dominant and not well behaved dog breed.

If you are ready for the challenge, the Cojack can become one of the best dogs you could choose to adopt.

Life Expectancy

The Cojack has a life expectancy of around 12 to 15 years, which is typical for small to medium-sized dogs.

With proper care, nutrition, and exercise, they can live long, healthy lives, providing their families with many years of love and companionship.

Another thing I love about the Jack Russell Terrier or any mix breed of the JRT or small dogs in general is that they generally won’t experience a large amount of health issue with proper care.

Stick to regular vet visits and stay up to date with shots and vaccinations and you can have a new family member for the next several decades.

The Takeaway

I think my opinion of the Cojack is clear.

My opinion of any mix breed that has 50% Jack Russell Terrier may be a bit biased but it’s definitely honest and what you can expect from this dog breed.

The Cojack is a fantastic mixed breed dog that combines the best qualities of the Jack Russell Terrier and the Corgi.

They are affectionate, loyal, and highly trainable, making them great companions for active families.

While they may require a bit of patience and consistency when it comes to training, the reward of having a well-behaved and obedient pet is well worth the effort.

If you’re considering adding a Cojack to your family, be prepared for plenty of playtime, exercise, and affection.

With proper care and attention, you’ll have a loving and loyal companion for many years to come.

Luna and I wish you the best of luck if you do plan on adopting in the near future.
