The standard form of Vitamin-E is usually sold as a gel cap in an oil base. Vitamin-E itself when in this form is dependent on the oil to act as a carrier for absorption. Usually a low percentage of it gets absorbed unless you really increase the fat intake of the dog.

The "dry form" of Vitamin-E comes in the form of a succinate salt. As such it is easily dissolved in water, and readily absorbed. I would stick with just 1-400 IU pill per day. Most likely if you wrap some melted cheese or peanut butter around the pill, it will disappear rather rapidly down puppy's gullet.

For the fish oil a dog that size should be able to tolerate 2000 mg 2X per day without problems. The only side effect from fish oil is that sometimes the GI tract gets too greased resulting in diarrhea. If this occurs cut back on the dosage.
