The incubation period (time between the introduction of the virus into the body and the onset of symptoms) in animals is highly variable, ranging from two weeks to several months. Incubation depends primarily on wound severity and size, and the distance from the bite to the brain. For example, bites to the head or neck as well as multiple and significant bites are associated with a shorter incubation period.
It is important to mention that rabid animals can transmit the virus through their saliva for up to 10 days before the onset of rabies symptoms. In other words, an animal that may appear healthy can still transmit the disease.
