I have found a lady with a yorkie puppy. She only sell yorkies and as 1-2 litter a year. Now, my question is that she wants 1/2 the cost for this female because her ears are not standing up and she weights more then her average puppys. She also has a male for sale that she is asking more for than the female but still 1/2 cost. This is a red flag to me? What do you all think??
