From my practical experience mostly symptoms arrive between 4-8 weeks

Even though it is rare but it is not impossible to have 1 year of incubation period. Basically, the incubation period is the time it takes for the virus to travel from an area of entry to the brain and cause symptoms. The virus travels 200 to 400 mm per day, so based on the animal height and area of the bite, the time period varies. In general, as per practical experience, we can say it takes a maximum of a few months to see the sign.
