The owner should soothe the dog's emotions and give it psychological comfort. If the wound is bleeding, you need to use sterile gauze to stop the bleeding, then use scissors to trim the hair around the wound to expose the wound, then clean the foreign matter in the wound with saline, disinfect it with disinfectant, and then apply antibacterial and anti-inflammatory ointment.

Finally, bandage the dog and put an Elizabethan collar on the dog to prevent the dog from scratching and licking. It should be noted that if the wound is large, it will need to be sutured in the hospital. If necessary, you need to take your dog to the pet hospital for vaccination.
