A dog tag is typically worn by a member of the military for identity purposes. This item bears this name because of the similarity to actual tags put on a dog. These are usually made of a light-weight silver metal and will have the name of the military individual listed on it. Additionally, a dog tag can alert others to a medical condition that the wearer may have.
A dog tag tattoo is usually selected by people who have served in the military. Some people choose to have an exact replica of the dog tag tattoo that has been worn. They are a means of identification as well as a symbol of significance worn as a real dog tag, or a tattoo. Since both the female and male gender is active in duty, this tattoo design is select by both of these genders.
