Humans enjoy their snacks: a bag of chips in the car, a granola bar at work, a handful of popcorn while watching TV in the evening. Some people maintain that grazing throughout the day is a healthier way of consuming calories. "Snackification" is even a growing trend among Millennials, who often don't have time to sit down for a proper meal.
I see a lot of overweight pets in my practice, which is a good opportunity for me to educate owners about the amount of calories in many of these small treats. For example, feeding your dog two large Milk-Bones is the equivalent of you eating a McDonald's hamburger.
