I am a fan of Vitamin C in dogs. (And people)
I take 2 grams once a day. That’s not a recommendation but it IS a statement of experience. I know how it feels, tastes and it’s influence on my health and habits. (There is a concern about bowel effects and I’ve experienced none)
Vitamin C is described in another article in the site. But this article you’re reading now, discusses the use of Vitamin C in powder form.
It also describes my calibration of some spoons you can use to measure it.
I bought little tiny spoons, two kinds. Plastic and stainless.
I bought a gram scale which I found VERY effective and easy to use.
Then I measured how much of the Vitamin C powder filled each spoon.
