What about PG (as in PG Tips) but if you are American then this will probably be lost on you. I say this because we do not recognise 'teacup' poodles in the UK, we have Toy, Miniature and Standard, and I believe the name teacup is given by breeders who breed particularly small versions of breeds or crosses.
What about - Velvet
or - Ebony
or -Blackberry
or - Lucky
Do let us know what you eventually choose.
Just be careful you don't tread on her if she's so tiny. :)
