In our animal science class, we were fed dog food (dog cookies) by our professor who claimed that if we were ever at war and had a shortage of food, we should keep water and dry dog food on hand rather than other types of food. His reasoning was that dry dog food provides all the nutrients humans need in a minimal package.
Is it safe to consume dog food in volume or regularly? Does it really keep a human in good health? What ingredients in dog food should we look out for?
