I have wondered about dog blood types
myself, and would guess that they are
"like" type O since they have probably
not evolved beyond it. I have one who is
sensitive to low-cost dog food, which
often contains wheat and corn, and
gets "itchy and whiny" after eating
it for a while. He does best on
vegetables, organ meat/chicken/
beef, and a little rice (to bind)
when I have the impetus to make the
food myself, but does well on ones
like Nutromax,too.

As far as Davis is concerned, I never
read any of her books, but once heard
that she was also big on bone meal, which
is high in lead and other pollutants.
That could be one of the things that
contributed to it.
