I dont like giving anti-biotics for no reason Socks, but having KC turn into pneumonia and being left helpless, when it could of been prevented, has left me in no doubt of the seriousness of this disease, and what it can do if it isnt treated properly. Personally, (and its my choice alone,) I always treat with anti-biotics, I respect everyone else's decision to treat their dogs as they see fit.
