Here is a raw food supplement. Comes with calcium or without.

And I use this green product sometimes:

Natural Dog Supplements & Vitamins

and also Dr. Harvey’s http://www.onlynaturalpet.com/products/Dr-Harveys-MultiVitamin-Mineral-Herbal-Supplement/269030.aspx

Stevia being plant derived would be ok in moderation of course, just like using honey.
