Rabies (Lyssavirus) is an infectious central nervous disease that is transmitted through the saliva (bite) of an infected mammal. The virus can only survive for a short period of time when exposed to open air. A dog infected with rabies becomes contagious to humans and otheranimals during the final stages of the disease when its body is shedding the virus. Dogs inflicted with rabies often appear agitated, disoriented, excessively drunk and will drool excessively. It's important to keep both your dog and family safe by having your dog regularly vaccinated.
