There is a possibility of developing rabies when bitten by a domesticated dog. The rabies virus enters the body through the mucous membranes of the body surface or the broken parts of the skin surface, eventually causing the patient to have a rabies attack. If a domesticated dog does not have rabies virus in its body, or if it receives regular rabies vaccinations without carrying the virus, it generally does not cause the injured person to get rabies, but the above is almost impossible to confirm. Domesticated dogs that have not received rabies vaccination, no matter how tame they appear, still have the possibility of carrying the rabies virus. Therefore, a bite from a domesticated dog should also be followed by a rabies vaccination in a timely manner, preferably within 24 hours. The injured person can first rinse the wound repeatedly with plenty of water and soapy water for 3-5 minutes so that the wound is adequately flushed and can be disinfected with iodine. In daily life, owners of domestic dogs should also pay attention to dog hygiene and health issues.
