Many age-related conditions in dogs are far more manageable when caught early. Regular health screening for senior dogs doesn't just detect problems—it provides peace of mind and helps you make informed decisions about your dog's care. This guide covers what to test, how often, and what questions to ask your veterinarian.
Quick take
- Annual blood work from age 5; twice-yearly from age 7.
- A complete blood count + chemistry panel can catch issues before symptoms appear.
- Weekly at-home tracking complements veterinary screenings effectively.
- Bring your tracking data to vet appointments for more informed discussions.
Why Health Screening Matters for Aging Dogs
The value of screening lies in catching changes early—when they're easiest and least expensive to manage. A kidney value that's slightly elevated today is a minor finding. The same value six months later, without prior data, might represent significant disease. Screening creates the timeline that makes early detection possible.
Recommended Screening Schedule by Age
For dogs aged 5–7, annual wellness exams with basic blood work (complete blood count + chemistry panel) are generally sufficient. From age 7 onward, twice-yearly check-ups and more comprehensive panels—including thyroid, urinalysis, and possibly blood pressure—become increasingly valuable.
Large and giant breeds may benefit from earlier screening, as they tend to age faster relative to their body size.
What Blood Work Reveals
A complete blood count (CBC) and chemistry panel can reveal early signs of kidney disease, liver dysfunction, anaemia, infection, and metabolic imbalances—often months or years before any symptoms appear. Newer markers like SDMA can detect kidney changes even earlier than traditional creatinine tests.

At-Home Monitoring Between Vet Visits
Weekly tracking of weight, appetite, energy, stool quality, water intake, and comfort provides invaluable data that complements veterinary screenings. Patterns that are invisible day-to-day become clear over weeks. The Longevity Scorecard is designed for exactly this purpose—a 60-second weekly check-in.
Questions to Ask Your Vet at Every Check-Up
Bring your tracking data to appointments. Ask about breed-specific risks, appropriate screening intervals, any new tests or tools relevant to your dog's age and health profile, and what specific values you should be watching. A collaborative relationship with your vet is one of the most valuable tools for your dog's longevity.
What to Do This Week
If your dog is over 7 and hasn't had blood work in the past 6 months, call your vet this week to schedule a comprehensive wellness panel. If they have, review the results with your vet at your next visit and ask about trends.
When to See a Vet Urgently
See your vet urgently if you notice any sudden changes in the patterns you've been tracking: dramatic drops in energy, refusal to eat, sudden increase in thirst, unexplained weight changes, or new lumps or growths that appear rapidly.
