Bleeding from a bite by your own dog should be vaccinated because of the possibility of rabies. Patients who bleed after being bitten by a dog indicate that the patient’s skin or mucous membranes are broken, and if the dog carries the rabies virus, it will transmit the rabies virus to the human body through saliva, infecting the patient with the rabies virus. Because rabies is incurable and 100% lethal after the onset of the disease, it is important not to take any chances and should be vaccinated in a timely manner. Clinical treatment of patients bitten by dogs is mainly based on prevention, the only effective prevention method is to inject rabies vaccine, which needs to be injected within 24 hours. For deeper wounds, tetanus antitoxin injection is also required. Patients with bleeding dog bites should first squeeze the blood around the wound outward, and then use running water to rinse the wound repeatedly for more than 15 minutes, and then go to the hospital as soon as possible after the rinsing is finished.
