I don't know if this is good or bad news. The new vet could not find anything wrong with Boston, no virus, no bacteria, no parasites. She said it's very unusual for a puppy to have had this many problems and that i may need to see a specialist.
She told me to continue with the metronidazole for a few more days, give him panacur liquid for 5 days and put him on hills prescription diet for a week. If his stool is not firm in a week I will have to be referred to a specialist
Please say a prayer for him tonight. He has been poked and prodded since he was 7 weeks and just keeps on going that sweet little boy of mine.
