Rare in Dogs
This bile is present in the womb of every female dog but the incidence of Bilverdine is rarely found among puppies. It stays inside the bloodstream throughout life but manages to keep itself away from one’s notice.
It happens very rarely when the Biliverdin joins in the amniotic fluid of the womb. That must have happened with Rio’s pup and that is why it was green in color. This was quite a rare occurrence and in fact, quite a special one.
