"If I could only point to one factor causing the modern-day pet obesity epidemic, it would have to be treats," says veterinarian Ernie Ward, founder of the Association for Pet Obesity Prevention and author of "Chow Hounds: Why Our Dogs Are Getting Fatter – A Vet's Plan to Save Their Lives."
Vets and animal-nutrition experts point the finger at fattening pet snacks: Packed with sugar and carbohydrates, even the tiniest packaged cheese or bacon snack becomes what Ward calls "calorie grenades."
"It's that seemingly innocent extra 50 calories a day in the form of a chew or cookie that adds up to a pound or two each year. By the time a dog or cat reaches mid-life, it's overweight and health risks begin to skyrocket," Ward says. Obesity is being blamed for health problems such as diabetes, joint pain and breathing problems in pets.
That doesn't mean the snacks have to stop, but experts say treats should make up no more than 10 percent of your pet's daily calories. That's not much, considering a 10-pound cat needs less than 300 calories daily and a 40-pound dog should only get about 1,000 calories.
Making things trickier, manufacturers don't list calorie contents on their packages, and they don't have to.
