FPS is normally associated with Canine Herpes and I attended a Seminar a couple of years ago, given by the manufacturers of a vaccine (for the bitch only) to prevent this. I will have to dig out my info and add it to this thread, but menawhile, one thing I do remember from the Seminar is that if CH is present in one or more pups, one way of pups recovering before they even rpesent with symptoms, (because symptoms can take a while a to show, and when they do it can be too late to save pup) is to make sure the area where the newborn pups are is at least 83 degrees in temperature - it the one thing that sticks in my mind and I always, always make sure my pups are toasty and warm, maintaining this temp can even save the majority of pups if they do present with this terrible affliction.
