Why does my dog eat everything in sight?

Our dogs’ wild ancestors had the ability to eat whatever was available and flourish. Dogs are omnivores, meaning they eat both meat and plant foods. Thousands of years ago, their ability to scavenge is what eventually led to them to form mutually beneficial relationships with humans. Humans produced garbage, and lots of it - and dogs thrived on it. It was easier, and much more energy-efficient, to scavenge than it was to have to hunt something down and kill it.

Even though we now feed our dogs high-quality, palatable food on a regular schedule, this instinctual behavior is still alive and well in them today.
