If your dog has an iffy tummy or itchy skin, start simple. Pick one easy protein (chicken or turkey is common), keep meals plain for a week, and watch how your dog does. When things look good, add a second protein and note any changes. Protein rotation over weeks helps you cover nutrients naturally. On the balancing front, calcium and phosphorus are the big duo. A typical target falls around 1.2–1.4 parts calcium for every 1 part phosphorus, with the total amounts matched to your dog’s needs
[1]. If you don’t use edible bone, no problem—add a measured calcium source to boneless meat so that ratio stays healthy. For omega-3s, oily fish is great; if fish is awkward, use fish oil or algal oil in measured doses. Start low, build slowly

Iodine lives in tiny numbers, so don’t “stack” sources (for example, don’t add kelp if your multivitamin already includes iodine)
[16][22][23]. Most trace minerals are handled by a sensible mix of meats and organs; a recipe checker helps you spot gaps rather than guessing
[1]. Supplements should be boring and targeted: calcium if no bone, omega-3s if no oily fish, a tiny iodine source if the plan needs it. Green-lipped mussel can be a joint extra in some dogs, but quality and dose matter and study results are mixed
