Is Blaze a hamster? I would say use a breast or a butt cheek for an elegant, tasteful profile of the beast, and reserve the other breast/cheek for a facing profile of Blaze II. Use of white and / or pink inks adds class.
Seriously however tattoos are very 1990s - if you want to honor a pet, make a donation to an appropriate charity.
I think it's weird. Maybe get a tatoo (if you must get one, because I think they are not good on girls especially, but guys either) of your spouse's name, or your kids, but not your pet. pets come and die too quickly to have something so permanent in honor of them. if you want to honor them get a little charm for a charm bracelet with their name or something.
