The Border Collie is a dog breed that originated in England. It is described as the best sheepherder dog in the world. Due to its stalking and eye contact ability, it can herd livestock.

It is a highly intelligent, energetic, and athletic dog. If you don’t train this dog properly, then it can even try and herd you. 

To remain healthy, the Border Collie requires daily exercise.

The Jack Russell Terrier is a dog breed that has its origin in England. It was originally bred by Jack Russell in the 19th century, who was a British priest.

It is actually the cross-breed of numerous Terrier breeds along with some Daschund roots.

In terms of temperament, this dog is intelligent, energetic, fearless, and athletic.

This dog is a hunting breed type dog and its main job was to catch rats.

To keep a Jack Russell Terrier fit and healthy, regular exercise is needed.

The Border Jack can inherit temperament-related traits from either or both of its parent breeds. Whatever the case, here are some qualities that you will most likely notice in Border Jacks:

  • Loyal
  • Playful
  • Courageous
  • Energetic
  • Intelligent

Are Border Jacks Aggressive?

Border Jacks aren’t usually aggressive and they are very active and playful dogs thus being suitable for active families. However, it’s not recommended to have Border Jacks if you have small kids because sometimes their play can be rough.

The parents of Border Jack, the Border Collie and The Jack Russell Terrier are both known for having high energy. So their offspring, Border Jack, is not different from them. 

Border Jack is a smart, fearless dog with a hunting heritage.

Now, although they are quite playful and friendly to humans, it is important to note they won’t tolerate any kind of harsh behavior.

As a Border Jack owner, it will become necessary for you to supervise your small kids around the house whether or not they get exposed to the Border Jack especially because of their hyperactive nature.

Are Border Jacks Good with Cats?

Border Jacks aren’t compatible with cats because they inherit a strong prey drive and herding instincts. While they may get along with cats if they are raised with other animals like cats from their puppyhood and socialized, it is still not recommended to keep them with other pets.

Border Jack actually combines the natural herding abilities of a Border Collie and also the energy level of a Jack Russel. And although this makes them great as farm dogs, it’s not so ideal for keeping them with other household pets.

If they aren’t raised from their puppyhood with other animals then it’s not recommended to keep them with other pets such as cats. 

How Long Do Border Jacks Live?

In general, the lifespan of Border Jack is 12-15 years. Both the parent breeds of a Border Jack, the Border Collie and the Jack Russell Terrier are healthy breeds. Your Border Jack is also expected to live a relatively healthy long life.

Considering any mixed breed dog, it is hard to expect what conditions they will likely develop. Usually, crossbreeds are healthier as compared to pedigrees but there’s no complete guarantee.

Also, note that there can be many breed-specific conditions, but not all hybrids will inherit them. 

The best way and probably the only way to determine what health problems a Border Jack may encounter is to look at the common health problems of both of its parent breeds.

Let’s have a look at some health problems of Border Collies and the Jack Russell Terriers:
