Hello

I have had an encounter with a small stray dog, who playfully jumped on my foot when I was walking by. I didnt feel or notice any bites at that moment, however 2 days later I noticed a very small dot like wound with scabbed blood on my leg, unsure if that could have been that dogs bite or something else. I have been vaccinated for rabies in the past. I have had 5 shots about 7-8 years ago, and then another 5 shots about 2 years ago. I have tested 2 months ago for rabies antibodies and titer was > 4.0 IU/ml. Should I be concerned with this and go for booster shots or is the titer protective enough
