how much garlic/brewer's yeast for my 100lb dog?

[momofmine]

Does anyone know of a weight chart that shows how much brewers yeast and garlic to give a dog for fleas? We have been trying to go the natural route to get rid of the fleas.

Brewers yeast and garlic aren't effective flea treatments. If you want to safely and effectively treat a flea infestation, you need to get a product from that works; you may like to try Capstar, which is a once-daily medication that kills every flea on the dog within thirty minutes, and leaves no pesticide residue. You can couple that with aggressive environmental control, including twice-daily vacuuming, changing the bag or emptying the bin every time, and treating the yard.

Don't give any dog massive doses of garlic--it can cause anemia in large, toxic doses.
