The first thing to make clear is that not all dog bites are likely to be infected with rabies, but it is about three days before to three days after the onset of rabies. Only after being bitten by a mad dog that has begun to detoxify in its saliva, there is a 30%-70% chance of being infected.
Generally, domestic dogs only have a certain chance of carrying rabies virus and do not cause direct infection. So if your dog is not playing around with unidentified wild dogs all day long, or it is not actively aggressive towards its owner or has other symptoms such as being restless and drooling, you can rest assured that it is healthy.
Of course, there is a safer way to judge, which is provided by the World Health Organization - when you are bitten by a dog with abnormal behavior and bleed, you need to get the first shot of rabies vaccine. Next, observe the dog that bit you. If everything is fine within ten days, there is no need to give the next vaccine. This is the international guideline of the WHO.
If it is a dog you raise at home, there will generally be no problems and it has not been exposed to any bacteria, so don’t be nervous. However, it is recommended that you vaccinate your dog if you have one. For safety reasons, a rabies vaccination is required every year.
