Vitamin E should also be supplemented if you give your dog tap water. The chlorine in tap water depletes vitamin E in the body.

I think 400IU would be fine for a boxer. I wouldn't worry too much about the amount in her food since much of the vitamins added to food are destroyed by heat, light, over time, etc. I give my dogs the 400IU capsules, they each get one capsule every other day.
