Here's the info on fish oil and vitamin e is taken from an article by Mary Straus published in the Whole Dog Journal, March 2007

Most fish oil gelcaps contain 300 mg combined EPA and DHA, and you can give as much as 1 of these gelcaps per 10 lbs of body weight daily, preferably split into two doses. If using a more concentrated product, containing 500 mg EPA/DHA, give 1 gelcap per 15-20 lbs of body weight daily. If using liquid fish oil, adjust the dosage so that you are giving up to 300 mg combined EPA/DHA per 10 lbs of body weight, and be sure to keep the product refrigerated so that it doesn’t become rancid.

You must supplement with vitamin E as well whenever you are giving oils, as otherwise the body will be depleted of this vitamin. Give around 100 IU to a small dog, 200 IU to a medium-sized dog, or 400 IU to a large dog daily or every other day. Vitamin E in high doses also has some anti-inflammatory effect.
