|Vitamin E is fat soluble, so all of that will be stored in the dog's body, making it difficult for dogs to flush the vitamins out of their system. I took this info from http://www.dogfoodproject.com/index.php?page=vitamins
Vitamin E (Tocopherol)
Effects: Acts as a biological antioxidant, and is required for normal reproduction. There are several forms of vitamin E. The most biologically active form is know as alpha-tocopherol, which should be supplemented as alpha-tocopherol, alpha-tocopherol acetate, or alpha-tocopherol succinate. Other forms, like gamma-tocopherol or beta-tocopherol, do not provide the same level of protection. Vitamin E from natural sources is labeled as alpha tocopherol or d-alpha tocopherol - dl-alpha tocopherol indicates a synthetic, less effective product. Do not give cheap vitamin E supplements that contain high levels of vitamin A, since this could lead to an overdose of vitamin A and possibly vitamin A toxicity. Vitamin E is also important for the formation of red blood cells and it helps the body to utilize vitamin K.
Deficiency: A deficiency of vitamin E can lead to decreased reproductive performance, retinal degeneration, and impairment of the immune system.
Toxicity: None known, but high levels of vitamin E can adversely affect the absorption of vitamins A and K, causing deficiencies. In the case of vitamin K this can interfere with normal blood clotting.
Stability: Vitamin E is sensitive to heat, light and oxygen and significant losses have been found after relatively short times of food storage.
Sources: Wheat germ, corn, nuts, seeds, spinach and other green leafy vegetables, asparagus, vegetable oils.
Sarah had Vitamin D toxicity, but that's different... You can call the ASPCA's poison control hotline to find out what to do. I think it's like $60.
