In the February 2012 issue of Veterinary Practice, we see again dog food recalls. The reason was wet weather in the Midwest causing increased aflatoxin levels, especially of corn, which should not be fed to dogs anyway. This illustrates the main problem of feeding even the highest quality processed foods. Sometimes the ingredients are not good, but you would not know that.
If you purchase the ingredients from a local farm you will know the quality, and if there is a problem, you will see it quickly. More on this later.
