If you homecook you will have to add several supplements. There is no one supplement that will meet all her nutritional needs. For instance, the recipe in the link I posted calls for:
SUPPLEMENTS:
* puréed veggie mix (up to 1 cup)
* 1 Tbsp olive oil, or 1/2 Tbsp olive and 1/2 Tbsp flaxseed oil
* 400 mg calcium (elemental, as calcium citrate or carbonate)
* or 1200 mg (approximately 1-1/2 tsp) bone meal powder (human grade)
* 1/4 tsp salt substitute (potassium chloride) — give 3 or 4 times a week
* 1 multiple vitamin-mineral supplement (human quality)
* 1 probiotic/digestive enzyme supplement
Dogs have a much higher calcium requirement than we do and the correct calcium to phosphorus ratio is critical. Please read this:

Homecooking is much more expensive, but well worth the results for a dog with health issues.
