She is still only 7 months old and while to me - she doesn't look fullblooded ...she sure has most of the yorkie look to her ....and if you love her - then that's what counts. She looks like a little sweetie
There are alot of breeders out there who don't care what they're breeding as long as they get our money - and yes - some do NOT tell the truth -
If I were you - try to report that breeder if you can. I can see you love her and it's a shame someone would take advantage of you - but these days - it's happening more and more. The worst scams are the ones where people spend money and don't even
get a puppy - so You are a lucky one to have her and I wish you all the best ...
The other way to look at this is... she is HEALTHY !! That is a huge bonus - and we see lots of sad stories right here on this site & who knows ? she may change and end up with lots of hair -

Just looking at Jaspersmom's baby is proof of how much a yorkie can change....and go for it with the bows - if you start now - by the time she has longer hair she'll be used to them.
