I'm a breeder who has many puppies dying rapidly. The symptoms are vomiting, diareah, loss of appetite, and bloody stool. It's not coccidia or giardia. The medications we've been using are flagil, albon, arethamiacin and our vet has no answer.

Typhus fever spread by rat droppings contaminating the grain the feed is made of? Coumadin in the feed? Go with whole defeathered chickens either raw or cooked to control diarrhea, mix with rice or hamburger and rice.

Parvo comes to mind. But I would think that a vet would catch that.
