Cody is 6 yo. He is having problems with prostatitis. This seems to come on when females in our neighborhood go into heat. Sometimes it just goes away other times he gets painful and continues to worsen, then the vet puts him on steroids to get rid of the inflammation. She recommended neutering. Cody also is the sweetest dog but at these times he can get very taciturn. He will lash out at Lucy if she plays too much and at us if we accidently do something to him, like step or trip over him. After lashing out he will follow you around and not leave your side just looking pitiful because he knows he did wrong. Will neutering help or harm?
