Information on a Border Collie and Jack Russell Mix

Updated February 21, 2017

Border collie/Jack Russel terrier mixes are common enough to have a nickname: "Border Jack." These dogs are a mix of two intelligent, fairly intense breeds. They can be complicated and challenging, but are affectionate and playful pets for people who understand how to handle dogs.

Border Collie

Border collies are herding dogs that hail from Scotland. Border collies are medium sized, with long black or brown and white coats. They are known as clever, intense dogs that take well to training. The AKC website refers to border collie breed as "the workaholic of the dog world."

Jack Russell Terriers

Jack Russells are small terriers that were originally bred in England to hunt and kill rats and mice. They are cheerful, smart and dedicated to their owners, but can also be stubborn and opinionated. These little dogs excel at working disciplines.

Border Jack Features

Border jacks are small dogs that stand taller than Jack Russells but shorter than border collies. they resemble terriers physically, with black and white colourations that follow both Jack Russell and border collie patterns. They are dense and very sturdy.

Border Jack Personality

Border jacks are born of two breeds that need regular exercise and stimulation. These dogs are extremely active, with bright, clever personalities that mimic their terrier and collie parents. They are bred for performance and used for agility training and competition because of their intelligence and high activity levels.


Border jacks require a lot of time and are not good dogs for new dog owners. These dogs are bred specifically for performance disciplines and must be handled with that drive in mind.

An owner who buys a hybrid dog takes a risk in that the breed is not set, which means that there is no breed standard or AKC control over breedings. There are no guarantees in regard to a dog's lineage, health or character.
