Yesterday's night a dog passed by my right leg touching the area between the knee and ankle of my leg. I have a little wound between the knee and ankle of my right leg. I think while passing the dog touched that wound by his body. There is no sign of bite , scratch, or any contact of saliva. He just passed touching that wound Is there any risk of rabies for me.
