How Is Rabies Diagnosed?
There is no accurate test to diagnose rabies in live animals. The direct fluorescent antibody test is the most accurate test for diagnosis--but because it requires brain tissue, it can only be performed after the death of the animal.

OP cites a story about a man who took his dog to the vet, and the dog tested positive for rabies, then the dog was taken to another clinic to verify the type of rabies.
