If the dog's eye is slightly scratched, it can heal on its own, but it is best to disinfect it to avoid infection. If the injury is more serious, it generally cannot heal on its own, and the owner needs timely help and treatment. If the area around the dog's eyes is injured but the eyeball is not injured, you can use saline or chloramphenicol eye drops to clean it, and then apply anti-inflammatory and hemostatic ointment. If the dog's eyeball is injured, it needs to be taken to the hospital for treatment immediately to prevent the condition from becoming more serious.
