Hello, Welcome to HCM, Rabies is a disease which is also transmitted by bite of the monkey, it is a 100% fatal disease but it is 100% preventable by proper and adequate treatment. As your mother was accidentally bit by your vaccinated pet puppy which has led to burning sensation at the bite site with out any open wound and the bleeding, according to WHO categorizes it has been categorized into Cat II. Cat II requires active immunization with antirabies vaccine on days 0,3,7,14 and 28, if the dog is healthy after the third dose she can discontinue the remaining two doses of vaccine in addition to this she should be given a shot of tetanus injection too. The aforementioned treatment will protect you against developing the disease rabies. Thank you.
