[Lady of Yorkies]

I have several people all interested in the same puppy. How do I choose who to go with? The first person sounds like she wants the puppy but she might choose her sister instead. I am taking both girls to meet with her on Sat. Also, both girls are over 7# and she might not take either one because of their size when she sees them. Another lady doesn't have enough money but she's offering me pick of the first litter when she breeds. She does want a larger girl. This one definately sounds like she wants the puppy. How should I choose? There are others interested in the same puppy but these two sound the most interested. Sylvia
