Regularly I give kelp tablets and flaxseed oil (or cod liver oil in winter)which are the main supplements, however I do use herbs and other things on a daily basis to add extra vitamins or as maintenance for cetain things, ie wheatgerm, bran, nettles, or dandelion, tree bark gruel, parsley, coconut, sesame seeds, crushed nuts, sunflower seeds, linseed mainly. Also if there is a certain situation going on with ones of the dogs ie illness or as in pregnancy then I use special herbs and natural foods to help with these things.
