Chronic Conditions Dominate this Year's List of Most Common Pet Health Problems

For the 15th year, Nationwide shares its most common pet insurance claims

Columbus, OH - Nationwide analyzed more than 3.3 million pet insurance claims submitted in 2025 from over one million insured dogs and cats. This year's analysis underscores a clear and ongoing trend: chronic diseases dominate the most common claims across both species, mirroring what many veterinary healthcare teams observe in practice. These conditions not only contribute to repeat visits, diagnostics, and multimodal management, but also can represent significant cumulative cost over time.

"Each year these findings remind us just how much our pets' health is shaped by ongoing, chronic conditions," said Dr. Emily Tincher, chief veterinary officer at Nationwide. "While not every illness can be prevented, early recognition and proactive management can improve outcomes. Our goal is to equip pet families, and the veterinary teams who partner with them, with insights that help support better long-term care."

Canine Trends: Allergies top the list again and chronic issues dominate the top 10

• No movement in the top 9 conditions, signaling persistent, widespread health patterns among U.S. canines
• Seizures enter the top 10 for the first time but are very closely followed by kidney disease and cranial cruciate ligament tears.
• Chronic conditions make up 6 of the top 10 and may require long-lasting care and follow families for years, underscoring the importance of ongoing care and budgeting.
