3. Book Reviews I'm 13 and I got the pack of the 2 dog tags books at a book fair. I just got done reading Semper Fido and I loved the story! I love dogs and I love the military so this has probably got to be one of the greatest book series in my life! p.s. It would be cool to have a book with a modern day navy sailor with his dog or a continuation of the 1st book. Review by Anonymous on Sun, 11/18/2012 - 2:25pm.
