Here is some reading I did on Wikipedia about Menadione.. since I didn't know anything about it. Sounds like it is okay in small doses but still seems kind of risky..

Menadione is a polycyclic aromatic ketone, based on 1,4-naphthoquinone, with a 2-methyl substituent.

It was formerly sometimes called vitamin K3, although derivatives of naphthoquinone without the side chain in the 3-position cannot exert all the functions of the K vitamins. Menadione is a vitamin precursor of K2 which utilizes alkylation to yield menaquinones (MK-n, n=1-13; K2 vitamers), and hence, is better classified as a provitamin.

Despite the fact that it can serve as a precursor to various types of vitamin K, menadione is generally not used as a nutritional supplement. Large doses of menadione have been reported to cause adverse outcomes including hemolytic anemia due to G6PD deficiency, neonatal brain or liver damage, or neonatal death in some cases. Moreover, menadione supplements have been banned by the FDA because of their high toxicity. Menadione has been used experimentally as a chemotherapic agent for cancer, ca 1945, but has lost ground to much safer, human form, vitamin K2 vitamers. Low level menadione is still used as an inexpensive micronutrient for livestock in many countries.

Lately, menadione has been mentioned again as a treatment for cancer in conjunction with vitamin C (See "The end of cancer" by April Kirkendoll) but modern researchers and trials are investigating nontoxic K2 vitamers such as menaquinone-4[1] in conjunction with more comprehensive regimens.

Although dogfoodanalysis.com has alot of beneficial information to aid you in your search for the non-existant perfect food, the information there is only based on the opinions of the site editors, not long term, extensive research.
I suggest trying the following link as well:
Dog Food Review Ratings
It links you to several sources that examine commercially processed foods, home cooking and raw diets as well as the pros and cons of each option. You can more than likely pick up any type of commercially manufactured product and find something in the ingredients list that you aren't 100% comfortable with feeding your little one.
Also, remember that what is best for one person's pooch may not be the best for YOUR little one. Research and find a product that has something to offer that you like and then try them out. You will know when you have found a good match for your baby from the results you see.
Also, there is a sticky at the top of this section that gives you contact information for various manufacturers that will often send you free samples to try or coupons for their products.

Good luck!

thank you so much for your reply. i have since purchased Dr. Pitcairn's book and i am working my sophie into a raw diet. i'm just a little confused about if i am feeding her an all raw diet, exactly what supplements should i be giving her. i have also found a holistic vet in ocala, fl (i live in jacksonville, fl) and already have her on nosodes instead of getting her vaccinated. any suggestions on vitamins and/or supplements would be greatly appreciated. byeee:

Ahhh...at last! Thank you so much for pointing that out.

I cringe whenever I see that website touted as the ULTIMATE dogfood authority (no offense to those who love the place.)

Glad I'm not alone!

Like I said, it's a good site to INCLUDE in your research, so long as your research doesn't begin and end there.
(The top ranked foods on that site almost killed one of mine and sent the other to the emergency vet, so clearly it's not a 'good fit' for every dog.)
