Keep in mind that a Newfoundland primary diet is normally fish based they need the oils to have healthy coats and skin. Make sure you not only use a fish oil everyday but add in fish as well to the kibble I use salmon or sardines only In water also several times a week I add in 1200mg of fish oil daily. We had crappy skin with litte sores for awhile tried several different foods finally ended up on fromm gold lb and the above plus I use raw veggies as snacks no dog cookies at all and her skin is great and her coat is soft and shiney. Becareful not to over bath her newfs are waterdogs who have a natural oil in their coat which will dry out if over bathed with shampoos
