Rabies is a viral disease of warm-blooded animals including human in which the inflammation of brain tissue occurs. The early symptoms of rabies are fever and signs of biting at the body parts by rabid animals. In another word, it is a deadly virus to spread to people from the saliva of infected animals by biting or another attack like scratch or contact with saliva. The rabies virus usually transmitted through a bite, direct contact of infected saliva.

This disease is a severe, and often fatal, viral polio encephalitis of warm-blooded animals and humans that mainly affects the grey matter of the dog’s brain and its central nervous system. There are few wild animals that are naturally carrier of rabies virus is skunks, foxes, raccoons and bats which transmit the virus by bitting to other healthy animals and man. Infectious virus particles are retained in a rabid animal’s salivary gland to disseminate the virus through their saliva better.      

Rabies Symptoms

In most of the cases, the rabies symptoms saw in the infected animals within the first week of infection or exposure. The early symptoms of rabies are very generalized problems in animals like headaches and fever without any history. The symptoms will not raise the body temperature and very similar to flue like the infection in your dogs. There are three stages of disease occur in progression:
