• Like a locket or a bracelet, you can use a dog tag to highlight something of importance in your life. Whether you want to highlight medical information or honor a loved one, you can engrave a dog tag however you'd like. Although a dog tag is very small, it can represent something of great value.
  
  

Picture

• If you have a loved one currently serving in the military or had one who died in the line of duty, go beyond carrying around their picture and get their image engraved on a dog tag. Bring a picture of your loved one to the engraver. Choose a picture of your loved one in civilian clothes to honor his commitment to you and your family or one of him dressed in his uniform to serve as a reminder of his commitment to his country. Consider engraving a picture of you and your loved one together.
  
  

Semper Fidelis

• The motto of the U.S. Marine Corps is "Semper fidelis," a Latin phrase which translates to "always faithful." Engrave your dog tag with this saying, whether you or a loved one is serving in the military. Adopted by the U.S. Marine Corps in 1883, the phrase "guides Marines to remain faithful to the mission at hand, to each other, to the Corps and to country, no matter what," according to the Marines website. Whether or not you or a loved is a Marine or member of the National Guard, the phrase "Semper fidelis" works well on a dog tag, highlighting eternal commitment.
  
  

Medical Information

• A dog tag in the military contains information like surname, blood group and Social Security Number to help identify the dead and wounded. Engrave your dog tag with personal medical information to guarantee proper medical care if you are found hurt. Consider information such as allergies, diseases, doctors' phone numbers, whether or not you have a heart stent and other vital medical information. Include a caduceus symbol or other symbol related to medicine to alert medical personnel that the dog tag contains vital health information.
