I've given Collo-Cal D as a preventative measure (
after whelping, never before) and have never had a problem with Eclampsia. We raw feed and also give extra rations while our bitches are feeding their pups, but I guess I don't know if that would be fine on its own.
In case anyone wants to research Collo-Cal D, there's some info
here. I must say, it sounds more versatile than I thought.
