Case 1: Dogs can scratch their skin without an injection.
It is a family dog, arresting people, and regularly vaccinating to repel insects; And the dog is in good health, has a normal mental appetite and has no cold symptoms.
I have little contact with other animals and have not been hurt or licked by other animals recently.
The reasons for being arrested are: pulling hard, teasing the dog to deliberately provoke, grabbing food, toys and so on. Or accidentally hurt it while playing.
If the above conditions are met, you don't need an injection if you are scratched, which means that the dog is healthy. Healthy dogs don't carry infectious rabies virus, so they won't infect people. Only dogs with rabies virus are contagious 3 days before and during the onset.
Hit the point! Even if you are scratched by a dog and your skin is not broken, you need to deal with the wound.
Even if the scratch is not visible to the naked eye, it can not prove that the skin is intact, because many tiny wounds are invisible to the naked eye, and bacteria are likely to invade the human body because of these tiny wounds, and may be infected with tetanus; Therefore, even if there is no wound after being scratched, it should be washed with soapy water 15 minutes or so, and then disinfected with alcohol and iodophor alternately for 2-3 times.
Case 2: If the dog is scratched and its skin is not broken, it needs an injection.
You are not your own dog, or you are not sure about your rabies vaccine and health.
Have cold symptoms, or have been in frequent contact with other animals recently.
Dogs have abnormal symptoms, such as trembling, listlessness, or obvious aggression.
The dog died within 10 days after scratching people.
Once one of the above situations occurs, dogs may carry or even be infected with rabies virus. It is best to have an injection as soon as possible within 24 hours. Even if the wound doesn't bleed and rupture, it's a second exposure. As long as the dog is infected with rabies virus, it may spread through this tiny wound.
How to prevent being bitten by a dog
