Tattoo should be interesting, carefully reasoned design with particularly deep symbolic meaning.
Not necessarily, no. As I said, tattooing is not (more) only sign of belonging to any social, religious or ideological group, but simply decorating the body and is now actually more associated with a fashion trend. If the tattoo represents a puppy (because you just picked that) represents the puppy. If this is an abstract pattern, then there is the result of the most aesthetic effect, and the like.
Sure, there are special traditional tattoo styles that have evolved over the centuries. Mostly, however tattoos represent a concrete, living motive: tiger, Scorpio, ship, soldier, devil, or say with a knife pierced bleeding skull ...
You can attribute the tattoo deeper meaning, or identifies in this way that you personalized set design - if you have tattoo of a Lion, you may think you are brave as a lion, and the like. This is perfectly acceptable and normal, but it is not necessary. All tattoos do not have a hidden, higher, or any deeper meaning.
