Healthy dogs can carry rabies virus, but the probability of carrying rabies virus will vary depending on the area. If you are in a city, most are pet dogs and have less contact with outside wildlife, so the likelihood of acquiring rabies virus and carrying it is very low. Many urban pets are vaccinated against rabies, which will further reduce the probability of carrying the rabies virus. According to some sources, in larger cities, the probability of a dog carrying rabies virus can even be 0, which means that no pet dogs carrying rabies virus have been detected, which is safer. If rabies vaccination can be popularized among dogs, this situation of dogs transmitting rabies to people can be further reduced or even eliminated. In rural areas where rabies is more prevalent, the rate of carrying the rabies virus in healthy dogs is relatively high, and according to relevant statistics, some can even be as high as about 7%, because most of these dogs are not vaccinated against rabies, and many are free-range and have more contact with wild animals.
