The importance of Vitamin C for dogs... who knew?

Thanks to a yahoo group I belong to; I am finding out all kinds of interesting info. This week, the topic as been the correlation between Vitamin C consumption and Hip Dysplasia. in canines. Here is an article which is relevant:

here is another great article on Vitamin C usefulness in a dogs diet from the Whole Dog Journal:

http://www.whole-dog-journal.com/issues/1_7/features/5309-1.html

The article does not give specific dosages; but there is literature out there that does.

"Cheryl Schwartz, DVM, “Four Paws, Five Directions: A Guide to Chinese Medicine for Cats and dogs.” Schwartz suggests giving vitamin C to dogs with a variety of illnesses, including upper respiratory conditions (small dogs, 125 to 500 mg. twice daily; medium dogs, 250-1,500 mg. twice daily; large dogs, 500-1,500 mg. twice daily), arthritis (to bowel tolerance), infected ears (small dogs, 250-500 mg. twice daily; large dogs, 500-1,000 mg. twice daily), and skin allergies (small dogs, 125 mg. twice daily; medium and large dogs, up to 750 mg. twice daily)."

 I tend to err on the side of less-is-more myself; but since at least in humans excess "Vitamin C" is excreted, maybe it's not so worrisome.
So, starting otday, my dogs are getting 250 mg of Vitamin C in their evening feeding!
