I fell in love with my girls the day I met them and it just grew more everyday.
I really don't understand the need for such a tiny dog & see people like you part of the problem with what's happening to yorkies. I don't mean that to make you feel badly - it's just an observation - people are wanting smaller and smaller & I just don't get it -
WHY don't you get a Chihuahua ??? They're tiny !
I think you should give her back because you probably will resent her and she deserves better. But I have a feeling unless you dealt with a breeder who has ethics - you may not be able to return her. Poor thing...with all the sick puppies out there I'm surprised that someone would return a puppy because of her size a whole week after having her.
GOOD luck to her....I hope things work out.
Someone mentioned there is no guarantee on dogs size - that's true. Your next try you
may end up with a yorkie the same size....
