I do not doubt for one second that many dog food brands are a poor diet for many dogs and can make them sick (we feed a lot of venison since dogs are carnivorous). My concern is that your vet is giving you information and advice that is counter to the mass of scientific information, and that this silly advice may extend to other recommendations. If you consult the American Medical Association, National Academy of Sciences, Food and Drug Administration, or American Association for the Advancement of Science, they have all issued statements confirming that GMOs are as safe and nutritious as non-GMO varieties of the same crop. While the public can be forgiven for being swayed by popular media, a care giver (even for animals), is dangerous when they ignore science in favor of sensational headlines.
