Great thread, i actually researched this a couple of weeks ago on the net when Leo was fading although at that point i sort of felt that he might make it, now and after he passed when i look at how his weight went down daily i should have seen that he was fading but i sooooo badly wanted to believe it wasnt FPS and that he would turn a corner. I now know if this occurred again in the future i would definitely source a recently vaccinated dog and try this process anything is worth a try. Thanks for adding it as it will be useful for others to know that this can be done xxxx
