Puff and I both take one Kirkland (Costco) Fish Oil capsule daily. The label says it also contains d-alpha tocopherol (which is a form of Vitamin E). Doesn't say how much in each capsule but I trust Costco's integrity.
Puff [YF, AKC field line (from competing HT/FT breeder) 62 lbs, dob: 8-'01]
Bess [BF, AKC bench line (from competing show breeder) 55 lbs., 1967-1981] "Poor Bess, the Wonder Dog":
I do 1 400 iu ( I think that's the measurement) of Vit. E in addition to 2 fish oil pills daily.
