We learned the hard way too! Our Wire Fox Terrier came from a breeder. I took him for his Parvo vax and he was fine for a while, but came down with Parvo he contacted at the Vet's office. We nursed him through at home and saved him. It might have been a lighter case the vet said because he had the vax. THe vet told us never to put apuppy down outside of home, never take him in public such as parks or lawns, until he is vaccinated and it has time to take effect. Now we keep our puppies inside or in the car except our own backyard until they are big enough for shots. I hope your boss' dog survives too. Parvo is a terrible death where they dehydrate to the point of failure. Our dog happened to love tea with milk and sugar and that pulled him through, although tea is not reccommeded for dogs, you can't tell us it was not worth it. The vet didn't think he was going to make it, but Thank Heavens, he did and now he is 14 years old! JoEllen in Central California where Parvo never dies!
