AAFCO is the petfood regulatory institute, unfortunately it is a volunteer organization, so no real controls. All sorts of nasty is in dog foods as well as poison and fertilizers that are not allowed for human consumption.Most pet food is a reasonably complete human diet...I say we make them redeemable only at pet stores; give people some motivation to get off of them!
Lost a dog to cancer and started researching dog food and we no longer feed that crap to my dogs, my dogs are on human food. Costs more but worth my peace of mind!!
