I'm very sorry about your allergies! But if you end up needing to sell her I would love to take her. I have a male yorkie that is the same age as her. I'm currently looking to find him a girlfriend, she would have an amazing home and if you every wanted another Yorkie I would be happy to let you have a baby
And just so you don't think that's all I want her for I will let you know that she will only get bred once a year and she is a present for my boyfriends mentally handicapped sister.
