Hi Sara
Supplementation for a home cooked diet can be difficult and very time consuming. There is a product called Balance It that makes things easier. You can pull a diet from
Welcome to Pet Diets for use with that supplementation product for about $25 (for healthy dogs with NO known digestive problems).
Supplementation is hard - I've done it for years and it's time consuming. We just started to use Balance It for two dogs on medical diets and one healthy dog. Each dog has different supplement needs because each has a different diet. So the supplements change as the ingredients change.
Good luck!
