Some veterinary visits are truly unexpected—as highlighted by our annual Hambone Awards®—but most pet health conditions are quite common indeed.

“Often when people think about financially preparing for different conditions for their cat or for their dog, we tend to think about the catastrophic things—the really unexpected things,” says Dr. Emily Tincher, Chief Veterinary Officer at Nationwide. “This top 10 list for dogs and cats is proof that the everyday health issues have the most impact, especially as you’re planning financially to care for your pet.”

We analyzed our database of more than 1 million actively insured pets to identify the most common medical conditions affecting dogs and cats—and the financial impact these diagnoses can have on pet families. Here’s what we uncovered, and what pet parents can do to learn more about common conditions for their pet’s specific breed and age.

Chronic conditions

Chronic conditions represent 50% of dog and 60% of cat conditions listed. A chronic condition is defined as a health issue that lasts for an extended period, typically more than six months, that requires ongoing medical attention. These conditions cannot usually be cured but can be managed with appropriate treatments and lifestyle modifications.

“From itchy skin to upset stomachs, the most common health issues affecting pets are the ones veterinarians see every day,” says Dr. Tincher. “When a pet is diagnosed with a chronic condition, the financial impact can be just as worrying as the diagnosis itself. Many of these conditions require ongoing care, with costs increasing significantly over time. Understanding potential health risks and planning ahead can help pet parents navigate these challenges and ensure their pets receive the care they need.”

For example, skin allergies are the top condition in dogs for the 13th year in a row. The initial cost to get allergies under control might come in around $265, but the annual cost to manage this chronic dog condition adds up to $841.

“When we acknowledge that skin allergies are usually diagnosed for puppies around 6 months old to maybe a young adult around 3 years of age, even if the cost of care didn’t rise at all over the lifetime of your dog, that means pet families are likely to spend $8,000-$10,000 just to keep their dog comfortable and not itchy,” says Dr. Tincher.
