MINNESOTA (CBS) ― From the looks of things, a dog's life is a good life. Between exercise, fresh air and playing with friends, they expend a lot of energy. So how does a pet owner fuel that passion?
Dr. Julie Churchill, a professor and Veterinarian at the University of Minnesota says told CBS station WCCO-TV, "There are over 5,000 different dog and cat food products on the market in this country alone. So it's a jungle out there."
The Pet Food Institute estimates that we spent more than $8 billion to feed our 67 million canine companions in 2007. That's a lot of mouths to feed.
