Want to show sharrre after the post? How to do?

Hi, I want to show sharrre button after the post. How can I do that? How to change location from post side pane to post footer after content ?

And also I am not able to find Google+ sharrre icon. Facebook, Twitter, and pinterest is available and working fine.
