Raw is an excellent way to feed, but you MUST know what you're
doing. There's good books out there that can help. If you want to
go that route, let me know and I'll tell you which books are
good. There's a few. Anytime you feed raw, calcium must be
added to the diet.
If bones are added in the diet as a source of calcium then you
don't need to add it as a supplement, however, you have to make
sure that you're truly adding enough bone to the meal.
IMPORTANT: If you're feeding a commercial food of any kind where
it's already balanced and calcium is included - NEVER add more
calcium.
If you want to feed raw, look at foods such as Primal or
Answers. Both are good raw foods and are already balanced. :o)
