I would honestly look for another breeder. You really want to make sure that you are taking home a little one that wont develop health issues down the road. There are certain issues that are genetic and a reputable breeder is aware of this a only breeds dogs with no genetic problems and as Lovetodream88 said only dogs that meet the breed standard. I would worry that if she is breeding a dog that is not a standard color that she wouldnt be selective with genetic health issues. Bottom line is that you want to feel that you can really trust your breeder. I want you to be very happy with your future yorkie
I can tell you that once you do find the right pup you are in for such a treat. Yorkies are the most amazing dogs. I have had other breeds but none have come close to capturing my heart the way that my little girl has
Can I ask how much the breeder is asking for the pups?
Hope that we are helping with your concerns and welcome to YT!!!
