Why dogs have rabies?

Rabies is a serious viral disease seen in mammals that adversely affects the central nervous system,which leads to death. Rabies is a zoonotic disease that is typically transmitted through bites from infected animals. The majority of reported cases involve wild animals like bats, raccoons and skunks, but domesticated animals like dogs and cats are also at risk. Humans are equally susceptible to the rabies virus if bitten by an infected animal. Once the symptoms have appeared, Rabies is nearly always fatal. Death usually occurs less than a week after the onset of signs.
