Have you ever heard of the Border Jack dog breed? If not, you’re in for a treat! The Border Jack is a designer dog breed that combines two very loved dogs into one!

If you’re looking to adopt a dog and aren’t sure what dog breed to adopt, then read on. Learn more about the Border Jack and if this is the right dog for you and your family. Let’s get started!

What is a Border Jack?

The Border Jack is a designer dog breed, also called a hybrid dog breed, which is a combination of a purebred Border Collie and a Jack Russell Terrier. The Border Jack is a relatively new hybrid dog breed and not much is known about the history of these dogs. However, we can learn more about Border Jacks by taking a look at both purebred parents.

Quick Overview of the Border Collie

The Border Collie is a distinctive dog breed known for this breed’s ability to efficiently herd sheep and cattle. The dogs were first developed in Scotland and England, where they were bred to herd cattle. Border Collies are known for their unflagging energy levels and stamina. The dogs were developed to work all day herding cattle across challenging terrain and in all types of weather.

These dogs are highly intelligent and love to work. These hardy dogs have sometimes been known to travel 50 miles or more in a single day herding cattle. This is a dog breed that has a strong work ethic. Border Collies love to have a job to do.

When it comes to being a family dog, Border Collies are best for active families that have older kids. They have a tendency to “herd” younger kids and other pets! Having said that, the Border Collie is very trainable and eager to please.

The Jack Russell Terrier

The Jack Russell Terrier originally came from England about 200 years ago. The dogs were bred to hunt and chase animals during the hunt. As you can guess, the Jack Russell is a bold, highly intelligent, determined dog! They are also popular dogs; however, what many inexperienced pet parents don’t realize is that these dogs are a challenge.

Jack Russell Terriers are not easily trained like the dogs you see in movies and TV shows. While they are very trainable, these dogs are independent thinkers. And they will come up with their own “fun” if left to their own devices.

Jack Russells are highly athletic dogs that excel in many types of dog sports, including agility, flyball, and more. They love to play fetch and enjoy all kinds of activities. This is a dog that can quickly into trouble by digging, chewing, and barking. They’ve even been known to streak through the house on occasion. Even so, these dogs can make great family companions for experienced pet parents.

With parents like these, how can the Border Jack go wrong? Well, we may have some information on that later!

The Border Jack usually stands between 15 to 22 inches tall and weighs between 22 to 32 lbs. They have a life expectancy of 12 to 15 years.

Border Jack Appearance

Border Jacks are hybrid dogs and don’t have a standardized appearance. That’s because each dog randomly inherits genes from both purebred parents. Even so, Border Jacks usually have a body that strongly resembles their Jack Russell Terrier parent, with a narrow body and chest. They usually have a small head and floppy ears.

The Border Jack may have oval or almond-shaped eyes that are dark. And these dogs have faces that are alert and intelligent. They tend to have a strong muzzle. The dogs’ feet can be round or oval and small.

Border Jack Temperament

As you may have ascertained, the Border Jack comes from two highly active, intelligent parents! So, you can expect these dogs to be bold, full of energy, courageous, and more. However, as with other hybrid dog breeds, each Border Jack is a unique individual. Some of these dogs may have the temperament of their Border Collie parent, while others more strongly resemble their Jack Russell parent.

Border Jacks can be hyperactive dogs that are highly intelligent. You can’t underestimate the intelligence of these dogs. If you do, the results will not be pleasant! These dogs can outsmart their pet parents, so you must always be on the alert with a Border Jack.

These hybrid dogs are not recommended for inexperienced pet parents. They’re best with active families who can spend plenty of time with their dogs every day. The dogs can be very affectionate and usually choose a favorite person in their family. They’re also very protective of your family and home and will do what’s necessary to protect their property and loved ones.

Are Border Jacks Good Family Companions?

Yes, they can be. These dogs are best for active families that have space for the dog to run and roam. They need time with their families every day and need regular exercise to stay happy and healthy.

However, if you have young kids, this may not be the dog for you. That’s because Border Jacks can be rough and hyperactive when playing.

Do Border Jacks Get Along with Other Pets?

No, Border Jacks don’t do well with other pets. For one thing, these dogs have a strong herding instinct and may try to herd small dogs, cats, and even kids. In addition, the dogs have a strong prey drive, making them go after small pets.

Border Jack Food Requirements

The Border Jack needs dog food that’s made for small, active dog breeds. They do best on a dry kibble diet. They need between 1.5 to 2 cups of kibble dog food a day.


When you have a Border Jack, expect to spend a lot of time with your canine companion. These dogs need at least two to three hours of vigorous exercise every day.

These dogs are very athletic and enjoy all kinds of activities, such as flyball, agility, and more.


Border Jacks are usually easy to train because they love to learn. They do best with positive reinforcement training methods, such as clicker training. And it’s a good idea to have a few treats and plenty of praise to offer when your dog does well!

One thing to consider is that Border Jacks may inherit some stubbornness from their Jack Russell Terrier parent. So, pet parents must be patient and consistent when training these dogs.

What’s more, some pet parents find it necessary to hire a professional dog trainer to work with them and their Border Jack.

Summing It Up

So, there you have it! The Border Jack is a highly intelligent dog that has a ton of energy. They’re trainable but benefit from a pet parent that’s dedicated to providing consistent training, with plenty of patience added in!

We’re pretty sure if you decide to adopt a Border Jack that you’ll have a loving, very adventurous companion for years to come!
