Important: Know the Signs of Seizures
Epilepsy is common in Border Collies, typically appearing between 1-5 years of age. If your dog has a seizure lasting more than 5 minutes or multiple seizures in a row, this is an emergency—seek veterinary care immediately.

The Border Collie Health Profile
Border Collies are generally healthy, long-lived dogs known for their intelligence and work ethic. However, they have several breed-specific health concerns:
- Epilepsy: One of the most common issues—usually manageable with medication
- Hip dysplasia: About 12% affected according to OFA
- Eye problems: CEA, PRA, and cataracts are concerns
- MDR1 drug sensitivity: ~2% carry the mutation—testing available
Major Health Conditions
1. Epilepsy (Idiopathic Seizures)
Common in breedIdiopathic epilepsy is one of the most common health issues in Border Collies. It typically develops between 1-5 years of age and is believed to have a genetic component.
Seizure Emergency Signs:
- • Seizure lasting more than 5 minutes
- • Cluster seizures (multiple in 24 hours)
- • Not recovering between seizures
- • First-ever seizure (needs evaluation)
Seizure signs:
- • Collapse, falling to side
- • Stiffening, paddling legs
- • Drooling, jaw chomping
- • Loss of bladder/bowel control
- • Disorientation after (post-ictal)
Management:
- • Keep seizure diary (frequency, duration)
- • Anti-epileptic medications
- • Regular blood monitoring
- • Most dogs live normal lives
- • Never skip medications
2. Hip Dysplasia
~12% affectedHip dysplasia affects about 12% of Border Collies. As an active breed, joint problems can significantly impact their quality of life if not managed properly.
Signs:
- • Reluctance to run, jump, or play
- • Bunny-hopping gait
- • Stiffness after rest
- • Difficulty rising
- • Muscle loss in hind legs
Management:
- • Weight management (crucial)
- • Joint supplements
- • Swimming and controlled exercise
- • Pain medication as needed
- • Surgery for severe cases
3. Eye Problems
Multiple conditionsBorder Collies can develop several eye conditions. Annual eye exams and DNA testing help identify problems early.
Collie Eye Anomaly (CEA)
Inherited developmental defect. Can range from mild to vision-threatening. DNA test available—reputable breeders test for this.
Progressive Retinal Atrophy (PRA)
Gradual vision loss starting with night blindness. DNA test available. Eventually leads to blindness but dogs adapt well.
Cataracts
Clouding of the lens. Can be hereditary or age-related. Surgery available if vision is significantly affected.
4. MDR1 Drug Sensitivity
~2% affectedAbout 1-2% of Border Collies carry the MDR1 mutation—lower than related breeds, but still worth knowing about. DNA testing can determine your dog's status.
Medications to Use with Caution:
- • Ivermectin (some heartworm preventatives, high-dose deworming)
- • Loperamide (Imodium) — over the counter, avoid
- • Acepromazine (common sedative)
- • Some chemotherapy drugs
Reaction signs:
- • Disorientation, stumbling
- • Excessive drooling
- • Tremors
- • Blindness
- • Seizures, coma
What to do:
- • Consider DNA testing
- • Inform your vet about the breed
- • Use MDR1-safe heartworm prevention
- • Avoid Imodium
Related MDR1-affected breeds: Collies (~70%), Australian Shepherds (~50%), and Shelties (~15%) have higher rates.
5. Trapped Neutrophil Syndrome (TNS)
Fatal genetic diseaseTNS is a fatal inherited disease where neutrophils (white blood cells) can't leave the bone marrow to fight infections. Affected puppies typically don't survive past 4 months.
Signs (in puppies):
- • Recurrent infections
- • Failure to thrive
- • Smaller than littermates
- • Chronic illness
Prevention:
- • DNA test available
- • Reputable breeders test
- • Carriers are healthy
- • Never breed two carriers

What is the lifespan of a Border Collie?
Border Collies typically live 12-15 years, making them one of the longer-lived medium-sized breeds. They're generally healthy but prone to epilepsy, hip dysplasia, and eye problems.
Do Border Collies have MDR1 drug sensitivity?
About 1-2% of Border Collies carry the MDR1 mutation, lower than Collies or Australian Shepherds. DNA testing is available if you want to know your dog's status.
Are Border Collies prone to epilepsy?
Yes, epilepsy is one of the most common health issues in Border Collies. It typically develops between 1-5 years of age and can usually be managed with medication.
What eye problems do Border Collies get?
Border Collies can develop Collie Eye Anomaly (CEA), Progressive Retinal Atrophy (PRA), and cataracts. Annual eye exams and DNA testing are recommended.
What is Trapped Neutrophil Syndrome?
TNS is a fatal genetic disease where white blood cells can't fight infections. Affected puppies rarely survive past 4 months. DNA testing identifies carriers—reputable breeders test for this.
