Gentlemen: I'm making no value judgments but simply saying if a MD and a Vet know nothing about Vit C for snakebite, it might be reasonable to assess this data with some skepticism.

Here's some more websites and you can decide if this all sounds reasonable:

This site DOES suggest sucking the venom BY MOUTH : http://www.pathlights.com/nr_encyclopedia/16pois01.htm

These are excellent sites regarding conventional evaluation and management:

Fortunately, Vitamin C toxicity is very rare:

And here are a couple re: management of snakebite in dogs

Bottom line:
"A snake bite should always be treated as an emergency even in a vaccinated dog.
If your dog is bitten by a rattlesnake, seek veterinary attention immediately."
