Nina Janes. It all started with a few cases of encephalomyelitis, paralyses in the hind quarter moving to the front within a few day's. Autopsies dit not show any injury's or other problems. Than a histology report was ordered and this showed a mild attack of the distemper virus. A vaccination program was put into operation. I now have used Distemper vaccines for a number of years with good and problem free success. Here in New Zealand, anything for ferrets is unprocurable, these animals are not well known as pets but as a vicious, smelly and wild beast. So I got mine vet to supply me with a vaccine for dogs, he was not game enough to do the 40 ferrets, and not having done this work myself it turned out quiet a experience. The vaccines I have used sofar are: Quantum-K9-3,Canvac-3 and Vanguard/DM. 1/4 dose of the normal dog. [Moderator's note: Before anyone gets any ideas about dosages, note that vaccines don't work this way: you need the same dose for a ferret than you do for a dog. Also see Dr. Williams' post in this issue about distemper vaccines. BIG] Regards BILL [Posted in FML issue 1311]
