Dog food

Dog food refers to food specifically intended for consumption by dogs. Like all carnivores, dogs have sharp, pointed teeth, and have short gastrointestinal tracts better suited for the consumption of meat. In spite of this natural carnivorous design, dogs have still managed to adapt over thousands of years to survive on the meat and non-meat scraps and leftovers of human existence and thrive on a variety of foods.

In the United States alone, dog owners spent over $8.6 billion on commercially manufactured dog food in 2007. Some people make their own dog food, feed their dogs meals made from ingredients purchased in grocery or health-food stores or give their dogs a raw food diet.
