In Part 2 of Mission RENAL, a series on Chronic Kidney Disease (CKD) in pets, Dr. JD Foster, small animal internal medicine and nephrology expert joins to explain how veterinarians interpret blood and urine tests to diagnose kidney disease, what IRIS staging means, and the importance of individualized treatment plans. Sponsored by Royal Canin and Elanco, this guide empowers pet owners with Real Education for Navigating Advanced Longevity in dogs and cats with chronic kidney disease.

Key Takeaways:

• Blood and urine tests together give the most accurate picture of kidney health.

• IRIS staging helps veterinarians guide treatment but doesn't define your pet's prognosis.

• Rechecks every 3–4 months (or more often if unstable) help maintain your pet's quality of life.

• Discuss lab results with your veterinarian—context matters more than red numbers.

• Each pet's journey is unique; don't rely on internet timelines or myths.

• Early detection saves lives. Routine screening can catch CKD before symptoms appear.
