Hi sir I am 20 years old I was taking a walk yesterday outside my office and there was small street dog we sometime feed him. I feel like he did something on my right leg was not sure though coz he did from the back I didn't saw him coming and then I went inside office and saw a scratch on my leg but not sure it was from dog side or ot was there earlier. I didn't see anything like sign of biting or a mark of dogs biting or scratching on my jeans that I was wearing. I immediately applied dettol on that spot and after 10 hourms I took titnus injection do I have to take anything else I am really worried
