Pet Food/Treat Start Ups

AAFCO’s Pet Food Committee has created a great tool for small pet food businesses to learn what is required when they wish to make pet foods and treats. Though this information is very beneficial in explaining what is necessary for a company to start up their business, it is just a tool. For further information regarding what is required by the state where you live, contact your State Feed Control Official.
