Alot of salmon oil supplements already have vitamin e in them (if it has rosemary extract, then it has vitamin e). It's used as a preservative in the salmon oil. If the supplement you choose does not have vitamin e, then you will need to add it as the extra omega 3's will slowly deplete the body's reserve.
Large/Giant breed dogs have more stress on their joints even under the best circumstances. Having the dog overweight, even just a tad, will increase that stress. Also, allowing the dog to jump on and off furniture or in/out of vehicles will jar the joints.
