Border Collies are a medium-sized breed at risk for joint, eye, and genetic disorders, making age-specific health screenings essential. Here’s a breakdown of recommended check-up schedules and must-have tests for puppies, adult dogs, and seniors.

| Item | Puppy (0–12 months) | Adult (1–7 years) | Senior (8 years+) |
|---|---|---|---|
| Basic checkup | Once a month | Once a year | Twice a year |
| Vaccination | 6, 8, 12, 16 weeks | Annual booster once a year | Once a year (at vet's discretion) |
| Heartworm & parasites | Monthly from 8 weeks of age | Monthly (year-round) | Monthly (year-round) |
| Blood test | Once (before neutering) | Once a year | Twice a year |
| Joint imaging exam | Once at 6–12 months | Once every 2–3 years | Once a year |
| Ophthalmic exam | Once at 6–8 weeks (CEA) | Once every 2 years | Once a year |
The schedule may be adjusted at the veterinarian's discretion

Drug Sensitivity Genetic Testing: A One-Time Lifetime Essential
Certain dog breeds carry genetic traits that affect how they metabolize medications, making them more sensitive to specific drugs. To determine whether your Border Collie should undergo genetic testing and which medications require caution, consult your veterinarian for personalized guidance. If testing is recommended, have it done early in life and keep the results in your pet’s medical records. Additionally, save a photo of the results on your phone so you can easily reference them at other clinics or during emergencies.

Visit the Vet Immediately for These Signs, Beyond Regular Check-ups
Even with regular check-ups, you should visit the vet immediately if you notice any of the following signs: limping that persists for more than 24 hours, cloudiness or injury in one eye, drinking more than twice the usual amount of water or a sudden increase in urine output, loss of appetite lasting over three days, or sudden behavioral changes or lethargy. Border Collies tend to hide pain well, so it’s important for owners not to miss even small changes.
