The real problem with dog food is that you really don't know what is going into it when you buy it. Dog food companies use phrases on their packages, such as chemical free, and no chemicals added to make you feel as if you were giving your dog the best food available, but what they do not let you know is that the regulations for dog food are not as stringent as those for our own food. The fact that they say they are chemical free just means that they have not added any chemicals since the products have come into their processing plant. Most of those products arrive packed full of junk and chemicals, and sometimes even meat from euthanized pets. They just do not need to disclose these things to you.
