DOG BITE / SCRATCH hi., a stray dog tried to bite my leg, failed to, caught hold of my shoe and when i tried to free myself its teeth caused a minor scratch on my ankle, was wearing socks. Seems to be a small scratch on my ankle, no sign of any blood.. The doc advised me a tetanus shot which i did take., is a rabies injection necessary? A bit worried as this is the first time this has happened..
