I have also have heard that the only way to tell if a dog has rabies is to examine it's brain under a microscope which means dead dog.
I hate this thread and yet I cannot stay away from it. As a Vet Tech for 15 years I can say that yes, the only way to test for rabies is to examine the brain cells. I also can't believe this thread has not been locked yet.
Too many uncivilized, animal killing monsters in here.
