Bleeding from your own dog’s teeth requires vaccinations, especially rabies vaccine, and if the wound is deep, tetanus antitoxin. Your own dog may carry the rabies virus, and even dogs that have been vaccinated against rabies may have a latent rabies infection. If you are bitten by a dog, you must be vaccinated against rabies. Because rabies has a very high mortality rate, prevention is important. In addition, if the dog bite wound is deeper, there may also be tetanus infection, and should be injected with tetanus antitoxin. Dog bite wounds need to be rinsed heavily with soapy water or water, and then disinfected with iodophor. Then get vaccinated as soon as possible.
