We love our pets. But sometimes, when it comes to rewarding them with treats and food, we might love them a little too much. As a result, our pets are increasingly overweight and obese.

Just last week, the group released its 6th annual survey. In the latest AVMA Animal Tracks podcast, Dr. Ernie Ward, founder of APOP, discusses this year's results. Listen to the podcast.
