Does a two-month-old puppy need an injection if it bites?

Two-month-old puppies usually have just been weaned, they usually still have antibodies, and rarely come into contact with other animals, so they are almost free of rabies; it is not necessary. Just give the injection and disinfect the wound. Rinse with soapy water for about 15 minutes and squeeze out some blood around the wound to bring out the pathogenic bacteria. Then use alcohol and iodine to disinfect the wound 2-3 times.
