The short answer
The Border Collie is generally a hardy, long-lived breed, but it carries some known inherited conditions: Collie eye anomaly and other eye problems, hip dysplasia, epilepsy, the MDR1 drug-sensitivity gene (which changes which medications are safe and is worth a DNA test), deafness (more in heavily white or merle dogs), and a few rare genetic disorders. Most are DNA-testable, so a rescue BC benefits from a baseline vet check. The everyday protections are keeping the dog lean, telling any vet about the MDR1 possibility, managing the SEQ heat for an over-driven dog, and insuring the dog young. This is general information, not veterinary advice.
The MDR1 gene: the one every BC owner should know
Of all the Border Collie health points, the MDR1 gene is the one most worth understanding, because it is easy to miss and genuinely important. MDR1 (multidrug resistance 1) is a genetic mutation, common in herding breeds, that affects how a dog processes certain medications. A dog carrying the mutation can have serious, sometimes life-threatening reactions to normal doses of some drugs, including particular parasite treatments, sedatives, anaesthetics and pain medications.
There is a simple, inexpensive DNA test, and it is genuinely worth doing for a Border Collie or BC cross, because it tells you and your vet which medications are safe. Whatever the test status, tell any vet treating your BC that it may carry MDR1, so they can choose medications accordingly, and be cautious with over-the-counter parasite products until you know. If you are unsure of a rescue dog's status, ask your vet about testing. This one piece of knowledge can prevent a genuine emergency.
Eyes: Collie eye anomaly and more
The main inherited eye condition is Collie eye anomaly (CEA), a developmental condition of the eye present from birth that ranges from mild and harmless to, in a minority of dogs, vision-affecting. It has a DNA test that responsible breeders use. Border Collies can also carry progressive retinal atrophy, a gradual inherited loss of vision, and other eye conditions, which is why breeding dogs should hold a current eye certificate. A rescue BC will not come with a breeding eye history, so a baseline vet eye check after adoption is worthwhile, and any change in vision, cloudiness, redness or discomfort is a veterinary matter. Most Border Collies, it is worth saying, see perfectly well their whole lives.
Joints, epilepsy and deafness
On the joints, Border Collies can carry hip dysplasia like many active breeds, and the athletic life of a BC also brings a real risk of cruciate ligament injuries and other wear from leaping, twisting and skidding at speed. Keeping the dog lean is the most protective everyday step, and reputable breeders hip-score their dogs using standards such as those from the Orthopedic Foundation for Animals.
Idiopathic epilepsy occurs in the breed, usually first appearing in young to middle-aged dogs as seizures with no other obvious cause; recurring seizures need veterinary investigation and are usually managed well with medication. Deafness also occurs, more commonly in dogs with a lot of white on the head or in merle-to-merle matings, and can be congenital in one or both ears. A rescue BC that seems not to respond to sound is worth a hearing check, and a deaf dog can still live a full, happy life with training adapted to hand signals.

See Available Border Collies →Rare inherited disorders, and the SEQ heat
The breed carries a few rare inherited disorders that responsible breeders DNA-test for, including trapped neutrophil syndrome (an immune-system disorder) and a form of neuronal ceroid lipofuscinosis (a serious neurological condition). These are uncommon, and the point for an adopter is not to worry about every one by name but to know that a proper vet assessment of a rescue dog, and prompt attention to anything unusual, is the sensible approach.
The bigger day-to-day health issue in Brisbane is the climate. The paralysis tick is a year-round danger in South East Queensland and a BC's medium coat hides one easily, so keep year-round tick prevention in place and search the coat after any bushland or long-grass outing. And a Border Collie's drive means it will run itself into heatstroke, so exercise only in the cool of early morning or evening, keep sessions shorter on hot days, and always carry water. General guidance is available from the RSPCA Knowledgebase and the Australian Veterinary Association, but your vet sets the plan for your dog. The exercise and heat balance is covered further in the adolescence and training guide.
Frequently Asked Questions
Are Border Collies a healthy breed?
Generally yes. As a working breed selected for function, the Border Collie is athletic and reasonably hardy, and many live twelve to fifteen years. The conditions to know are mostly inherited and DNA-testable: eye conditions including Collie eye anomaly, hip dysplasia, epilepsy, the MDR1 drug-sensitivity gene, and a few rare genetic disorders. Deafness also occurs, more so in heavily white or merle dogs. None of this makes a BC a sickly dog, but it is why keeping the dog lean, telling any vet about the MDR1 possibility, and insuring young all matter. A rescue BC arrives vet-checked. This is general information, not veterinary advice.
What is the MDR1 gene in a Border Collie?
MDR1 (multidrug resistance 1) is a genetic mutation, seen in Border Collies and several other herding breeds, that affects how a dog processes certain medications. A dog with the mutation can have dangerous reactions to normal doses of some drugs, including particular parasite treatments, sedatives and pain medications. There is a simple DNA test, and it is genuinely worth doing for a Border Collie or BC cross, because it changes which medications are safe. Tell any vet treating your BC that it may carry MDR1 so they can choose medications accordingly. If you are unsure of a rescue dog's status, ask your vet about testing.
What eye problems do Border Collies have?
The main inherited one is Collie eye anomaly (CEA), a developmental condition of the eye that ranges from mild and harmless to, rarely, vision-affecting, and it has a DNA test that responsible breeders use. Border Collies can also carry progressive retinal atrophy (a gradual loss of vision) and other eye conditions, which is why breeding dogs should hold a current eye certificate. A rescue BC will not come with a breeding eye history, so a baseline check is worthwhile, and any change in vision, cloudiness or eye discomfort is a veterinary matter. Most BCs see perfectly well their whole lives.
Do Border Collies get epilepsy?
Idiopathic (inherited) epilepsy occurs in the breed, typically first appearing in young to middle-aged dogs as seizures with no other obvious cause. A single seizure is frightening but not always the start of epilepsy; recurring seizures need veterinary investigation and, if epilepsy is diagnosed, it is usually managed well with medication that lets the dog live a normal life. Any seizure is a reason to see your vet, who will want to rule out other causes first. It is not a reason to avoid a rescue BC, but it is a condition to be aware of and to act on promptly if it appears.
Should I get pet insurance for a rescue Border Collie?
It is worth it, taken out while the dog is young and healthy so nothing is later excluded as pre-existing. Border Collies are generally sound, but eye surgery, epilepsy management, a joint problem or a cruciate injury from an active life can each add up, and insurance turns an unpredictable cost into a manageable premium. Compare policies on their exclusions, waiting periods and annual limits rather than on price alone, and read the product disclosure statement. Insurance works alongside the everyday basics: keeping the dog lean, managing the heat, and staying up to date on vet care.
