A dog that scratches a person with its nails and breaks the skin, but there is no bleeding, is a typical secondary exposure. If there is bleeding, it is a case of tertiary exposure. Secondary exposure is subject to appropriate prophylaxis, which means that the person is given a shot, a rabies vaccine to prevent rabies. If the degree of exposure is tertiary, the person is given a rabies vaccine along with a serum injection. In the case of secondary exposure, no serum injection is required, only rabies vaccine. So in this case, it is not possible to exclude the possibility of transmitting rabies to a person. If a dog bites a person with its teeth, it is possible to infect the person with rabies by staining the wound with saliva. A dog that scratches a person with its paws and breaks the skin may also transmit rabies to a person from the wound due to the small amount of rabies virus contained on the paws. The dog’s paws may also contain dog saliva, although the amount of saliva contained is relatively small, but it is also possible. So a dog paw scratching a person should be treated the same as a dog’s teeth biting a person.
