Last year brought some heavy news for pets-and their health. In a press release Nationwide reports that its members filed 1.4 million pet insurance claims for conditions and diseases related to obesity-racking up more than $62 million in veterinary expenses. And obesity-related claims swelled 24 percent over the last four years.

Nationwide recently sorted through its database of more than 630,000 insured pets to determine the top 10 most common dog and cat obesity-related conditions. Here are the weighty results:

In 2016, Nationwide reports that it received more than 51,000 pet insurance claims for osteoarthritis in portly pooches-the most common disease aggravated by excessive weight-and the average treatment fee was $310 per pet. Cystitis, the most common obesity-related condition in less-than-svelte kitties, garnered more than 5,000 pet insurance claims, with an average treatment cost of $443 per pet.
