I'm back...Thanks for the advice...I didn't go ahead and get her .she was pretty but scared shaking all over....But she kinds didn't look like one My sisster put her down to see her better we wanted her to walk to see how she does...I seen there was a darker color showing and my ssister saw that too we looked at her closier and she didn't have hair under the top hair ...she is white with just a little strings of black through her hair and I seen on the skin a black mole.....Then on her stomach wa alot of small moles or dirt not sure .But she told me she jut gave her a bath before she brought her to me ..I said what if she messes you alot and she said she won't...That surprised me also she had her for 3 yrs she said so i figure the dog would miss her..So I didn't do it thinking she might be a yorkie but like you all said they lose hair sometime with differnt colors ...so we was on are way home and my sister told me sshe looked like a crested hairless dog...Barbie
