What should you do if your dog scratches your skin?

If your dog scratches your skin, you should disinfect the wound immediately and rinse the wound with plenty of running water (20% soapy water is best) for 20 minutes. While doing the above, squeeze out some blood around the wound, then alternately disinfect with iodine and medicinal alcohol, repeat 2-3 times until the bleeding stops naturally. No bandaging is required, leaving the wound fully exposed.

Do I need an injection if my skin is scratched by my own dog?

In this case, no injection is required
1. The dog is a domestic dog and is regularly vaccinated against rabies and internal deworming.
2. Rarely come into contact with other animals, and have not been hurt or licked by other animals recently.
3. The dog is in good health, has no cold, is in normal spirits, and has a normal appetite.
4. There are reasons for biting, such as being provoked or threatened; being pulled by force; deliberately irritating; competing for food; protecting children; being hurt, etc. The bite will be as active as usual after the bite.
Meeting all the above conditions is indispensable, and vaccination is not required. The dog is basically healthy and does not carry transmissible rabies virus, and the chance of infection is extremely low. Dogs that exhibit obvious behavioral abnormalities will need to be vaccinated against rabies.
