None. All packed foods are crap that will effect the health of your companion in the long run. To an adult companion give brown rice plus curd in the morning, raw bone with meat for lunch, and a couple of raw eggs with brown rice in the evening. If you cannot withstand the site of raw bone with meat then for lunch give fresh grated white paneer together with vegetable puree and mixed grated fruits for lunch. In the latter case add some homemade hard whole wheat biscuits as treats that would keep the dogs teeth clean. Further, do not over vaccinate and only vaccinate if your companion is not sick. Beyond a couple of boosters and that too only for distemper, parvo, CAV2, and para-influenza and rabies vaccinate once in three years and never to an elderly companion. Lastly, keep you pet away from street mutts and other sick/unvaccinated pets. Train it to eat only on your command, nothing from strangers, and give it a lot of exercise. I learnt most of this the hard way.
