My female recently had a litter of puppies and one of the puppies that were sold came down with a bacteria they are saying was spread from the mom and that she will die and all the other puppies who are not sick or show any sign of being sick will also die, the puppy apparently had blood in its stool today and was lethargic, but these are the first and only symptoms of this? ANSWER
