What do you think about these tattoos I want to get?

Okay so, I have 2 of the most amazing dogs ever. I've had one for 2 years, and he's 3 years old. The other one, I've had since August of 2009. They mean a lot to me.. and when I turn 18, I want to get a paw print tattoo on each inner wrist, with the names Toby and Billy under each one. What do you think of this idea? Thanks..
