Temperament and Behavior

Border Jacks, because of their hunting heritage, are fearless, lively, smart, and vocal dogs with great working ability. If trained properly, these loving, devoted, and amusing dogs make excellent family dogs.
Once fully grown, they could become the perfect running partners of their owners. In fact, they are always ready to run, eagerly keeping pace and never complaining about being tired.

Although they are friendly towards humans, they are not tolerant of harsh or abusive behavior. Their rambunctious nature could be overwhelming for young kids, and so their interactions should be supervised. The Border Jacks do not accept the presence of other canine pets and may even confront larger dogs.



It needs a minimum of 30-40 minutes of vigorous activities to satisfy its regular exercise requirement. Your Border Jack loves to scamper, jump, play, and fetch. Moreover, you can also keep your dog active by involving it in dog sports including agility or flyball.


To remove all the loose and dead hairs, the Border Jack’s coat should be brushed every week. While it occasionally needs a bath, rough or broken coats should be stripped twice a year. Brush its teeth 2-3 times a week to prevent bad breath and tartar buildup. Also, trim its nails every month if needed.

Health Problems

Your Border Jack dog may be affected by some health issues such as allergies, deafness, glaucoma, patellar luxation, legg-calve-perthes diseases, progressive retinal atrophy, epilepsy, and hip dysplasia.


Border Jack pups could be a challenge for the timid or inexperienced dog owners. Since they can be stubborn at times, they need firm, fair, and consistent training.

  • To reduce your Border Jack’s aggression against other dogs you need to work on socializing your pet. The pup should be introduced to new objects, places, and people only when the experience is controllable. Since the puppies sense or observe their owners’ reactions, you can make it noticeable to your pup that you enjoy meeting other people and animals.
  • Training for flyball can be started at home by teaching your pup to retrieve a ball. If your Border Jack loves chasing balls that are rolling, you can simply wait for the rolling ball to stop and then release your pet to get it. Reward it with lots of praises and treats every time it brings the ball near you.


Your Border Jack’s diet should comprise foods high in protein. The recommended amount of dry food is 1.5-2 cups a day.

    I am in Houston, Texas and am fostering 2 Border Jacks. Adorable. The momma is very loving, gentle and not hyper. She is so smart. I wish I could keep her. The pup is not with me. I know she takes a while to get use to men.

    I’m a truck driver and I rescued a 5 week old Border Jack from another Driver. He was trying to feed him his dogs dry dog food. The baby couldn’t eat it so he fed him human fast food. The baby was very malnourished and had sardotic mange. He was covered in urine and feces with open sores. He smelled like he was rotting. He was lethargic when I got him to the Vet. His muscles were so weak, his legs turned every which a way. He seemed to have ataxia so I named him Jack Sparrow. He is 10 weeks old now and getting healthy. He knows Sit and No. He is intelligent and eager to please. I am doing his basic training but I feel that he will be perfect as a Service Dog. Time will tell but I think he has the right personality.

    Please let me know if there are any of the jack russell border collie mixes in British Columbia.

    My jack russell border collie cross Neeka (meaning Princess in Haida) passed away this past August and still it brings tears to my eyes as I miss my companion, sidekick and best friend. I got her from the Queen Charlottes.

    I know this breed very well and would love another chance to have one as my companion. My dog goes with me everywhere there’s no leaving the dog home unless I am at a place that is way to hot for my pet to be. Which with me if it’s that hot I probably not want to be there myself. Thank you. Eddie
