A dog produces 4 to 6 grams of vitamin c a day depending on size, ill or poisoned he will produce up to ten times that amount! Are most americans not ill or toxic!
The amount of nutrients in out food was twice what it is today 30 years ago and decreasing continually as our soils are being depleted of nutrients! I think we need to supplement one way or the other, especially if ill! You decide and make the best informed choices possible!
