Hi Ming! Post dog bite treatment consists of Local treatment of the wound, Inj Tetanus toxoid, Vaccine therapy - FIVE doses of Inj Antirabies vaccine given in the deltoid muscle (on 0, 3, 7, 14 & 30 days schedule) should be initiated immediately with the bites of categories II and III. For category III bites immediate vaccination and administration of rabies immune globulin ( along with the first dose of vaccine) should be given. Types of dog bite are: Category I – touching or feeding animals, licks on the skin Category II - nibbling of uncovered skin, minor scratches or abrasions without bleeding, licks on broken skin Category III – single or multiple deep bites or scratches, contamination of mucous membrane with saliva from licks. Treatment may be discontinued if the dog or cat remains healthy throughout an observation period of 10 days; Regarding the treatment of bite inflicted by a vaccinated dog. A vaccinated dog is not always a guarantee that it is not rabid. Vaccine failures may occur because of improper administration or poor quality of the vaccine, poor health status of the dog, and the fact that one vaccine dose does not always provide long-lasting protection against rabies infection in dogs. Hence, appropriate documentation of vaccination status of dog and proper history should be elicited before deciding to defer post-exposure prophylaxis after bite by vaccinated dog. Hope the suggestions given above could be of great help in getting the prophylactic treatment following a dog bite. A feed back is highly appreciated.
