Marmaduke –
I give my dogs 1 tsp. of an animal based omega 3 (sardine oil or anchovy oil generally) and 1 tsp. of a plant based fat (flax, evening primrose, borage or sometimes sprouted chia or coconut oil). I split 2-400 i.u. vitamin e capsules between the three of them – so that would be about 267 i.u. each per day. For a large dog anywhere between 100 and 400 i.u. per day should be adequate, however I wouldn’t go over 400 i.u. per day. I have large dogs, since you have golden retrievers that are probably around the same size as mine these doses should be fine for your dogs.
