Gus is almost 17 monthes and he's only 2.9 lbs. I love SpoiledYorkie
http://www.spoiledyorkies.com/index.html Robin is very sweet and will custom make clothing. I have been ordering from her from day one. Gus was only 1.4 lbs when I brought him home at 10 weeks. She makes xxs and will go even smaller if you need. It's so funny because I kept all of Gus's clothing just incase we are blessed with another yorkie. For laughs we like to put his tiny shirts on him,,,,,, He looks so funny. they still fit,,, just a bit short. They look like belly shirts on him. SpoiledYorkie is a bit costly but they sure do have darling clothing.
