Yes, neutering is recommended as the first step however, it is not a guarantee that it resolve the issue. Testosterone levels take about 30 days to go down after neutering so you may not notice a change right away. I strongly suggest you get him neutered and also seek the help of a professional trainer before this dog hurts somebody.
