My recipe I'm developing for my little darlings to see if we can affordably cook for them instead of having to worry about them eating rat poison. Adding up the cost of all ingredients, it adds up to around 15.00/week, which is the most I can afford to spend! This makes enough to keep 2 55 pound dogs happy and fed for a week. You still need a supplement, one with a good amount of calcium and phosporus and zinc, but I did spend hours amending this recipe to make it match a 55 lb dog's nutritional needs-I just couldnt get enough zinc, calcium or phosphorus! I left a little wiggle room as far as calories-around 300 calories/day extra for treats, dog friendly table scraps, etc. My dogs adore this! It's important to use soybean oil or (even better) safflower oil, as this oil contains a high amount of linoleic acid, which dogs need.
