On Supplements

Fish oil, Vit E, Vit C are all necessary supplements. Nori or sea weed will also contribute to their overall health. Alfalfa powder, wheatgerm etc is also good for them.

Just a spoon of vegetable(corn) oil or olive oil to their food will take care of their needs generally. Some people add multi vitamins and calcium tablets to the dog food. If the cooked meal isnt sufficient or wholesome enough, this is a good idea.

I would rather go for natural sources from food rather than add multi vitamins. I would rather give the multi vitamin just twice or thrice a week. No need to include it everyday.
