A week ago I was sitting in a park talking to my friends . Some of my friends are dog lovers they were giving biscuits to street dogs . Suddenly one of the dog came behind my back and startled me. Now I am thinking that somehow that street dog bit me and I didn't even noticed it. After 3 days of incident I check my back there were 2 red marks spaced 1 cm apart. It could be pimples. But I am very frightened now. Could I have been infected by rabies. Can anyone be bit by a dog and didn't even noticed. Plus the dogs were very playful and looking healthy. Please help me as anxiety is getting the better of me and I am feeling like loosing control over myself.
