It’s no secret that Americans waistlines have been expanding for years, and a new report shows our pets are following suit.

Banfield Pet Hospital’s 2017 State of Pet Health report found that one in three pets who visited Banfield pet facilities in 2016 was overweight or obese. The annual report details health habits of the 2.5 million dogs and 500,000 cats who visited facilities across the country in 2016.

Dr. Kirk Breuninger, a veterinary research associate at Banfield Pet Hospital, said they noticed a trend in pets gaining weight five years ago.

“More than 20 disease conditions have been linked with pets being overweight,” Breuninger said. “While some may say, ‘My pet looks cute being pudgy or plump,’ ultimately carrying those extra pounds contributes to exasperating these diseases.”

Breuninger said a healthy weight could prolong a pet’s life and delay chronic disease. He notes that the report found that the prevalence of overweight pets coincided with an uptick in arthritis and tracheal collapse in dogs.

And overweight pets aren’t easy on pet owners’ wallets.

The report found that over a four-year period, owners of overweight dogs spend 17% more in healthcare costs vs. owners of healthy dogs, and owners of overweight cats spend 36% more in diagnostic procedures versus owners of healthy weight cats.

He said a cocktail of factors could play a part in pets gaining a few extra pounds.

“We know a few things that are really linked with pets becoming overweight, one of which is pets not getting enough exercise, pets eating too much food, and pet owners who really consider pets a part of the family use treats as a form of communication with pets,” he said.
