I got this one from someone a few years ago. It works well. I've changed it a lot but it's a good start:
Home Made Dog Food
1 lb lentils or split peas, overcooked using only enough water to keep them from sticking
Add in pureed....
2-3 cloves garlic
2-3 medium sweet potatoes
2-3 carrots, but not every time
6 to 10 eggs
l lb fresh or frozen green leafy veggies (we're using kale)
up to a 1 lb of other veggies (okra, broccoli, sometimes beats, green beans, zucchini, sometimes mixed veggies, once in a blue moon something like corn, carrots or peas which are higher "starch")
about a cup of fruit (you don't have to use fruit, but I like to.)
1/2 lb organ meat
1/2 tsp egg shell powder or appropriate amount of human grade calcium supplement per pound of boneless meat
7 lbs raw meat (or 7 cans, WELL rinsed and smushed jack mackerel, no need to add calcium with this)
