There is no scientific evidence to suggest that the chances of contracting the rabies virus from a dog scratch are zero, and patients need to be actively vaccinated against rabies to prevent infection. Even though the rabies virus is mainly found in the saliva of dogs, it cannot be assumed that the chance of infection at the site of a scratch is zero. Canines are the main carriers of the rabies virus, and their saliva may carry a large amount of rabies virus. Although canines do not have the habit of licking paws as cats do, it cannot be assumed that 100% of dog paws do not carry the rabies virus, and it can be assumed that scratches from dogs have a smaller chance of infection than dog bites. After being scratched by a dog, the injury should still be treated promptly and great care should be taken to prevent rabies infection. Since rabies is preventable and not curable, it is recommended to get vaccinated in time under the guidance of a doctor, and it is not believable that the chances of contracting rabies from dog scratches are zero.
