i said it before and i'll say it again, a teacup is not a dog,a teacup is a CUP for TEA....
"oh hey lets breed the worlds smallest chihuahua!" what a great idea....NOT!
also always entertaining, the breeder who even top the "teacup" expression with calling them "tiny toy teacups" (interesting enaugh the IQ of the breeder seems to shrinks with the size of the puppy)
