<s>[INST] I was feeding a stray dog when it grabbed a biscuit from my hand. It's teeth seems to have scratched my thumb. Just a tiny dot as small as a pin head. There was no major bleeding. Just reddish a little blood appeared on the surface. I washed it with Dettol. Do I need to take an anti-rabies shot ? [/INST] hi,   I understand your concern.   Unless the biting dog is a pet /known dog & has been vaccinated-  /unknown dog bites need protection by anti rabies vaccine & Tetanus toxoid injection.    About stray dog bite, I would suggest use of human antirabies serrum along with anti rabies vaccination doses- after consulting local health officer.    Thanks. </s>
