Always check the AAFCO label

The Association of American Feed Control Officials, also known as AAFCO, is a voluntary membership association of local, state and federal agencies. Their members are charged by their local, state or federal laws to regulate the sale and distribution of animal feeds and animal drug remedies. They can help you choose the food that contains all the nutrients that you need for your pet. Nonetheless, AAFCO does not guarantee you that the nutrients are actually in those products and to make sure that you are on the right path you should check the European Pet Food Industry guidelines – it will help you with the nutrients levels that should be in some ailments.
