I had 2 cats that were Delta Society Therapy cats for years. If Delta has not changed their regulations, they accepted a 3 year rabies shot and the regular annual distemper. One of the therapy cats had several bad reactions to the distemper, so they did accept the homeopathic nosodes. Maybe you should see if your dog could be a Delta therapy dog. Tell them Spunky and Ralph(Lifetime Achievement: Therapy Cats of the Year, 1995) sent you!! Good luck!
