I urge you to reconsider getting rid of them just because they are too small. I did that when Addie outgrew her XS then had to buy new outfits when Skeeter came along. He outgrew his XS's and I, again got rid of them only to later adopt Gracie who is an XS!!!!!
Just pack them up until you are sure there will never be another yorkie puppy in your house! Just like baby clothes!!!!!
