I use Preemie baby jackets that I found at wall mart for $3.99. Preemie size fits Yumi Yasha perfect ( she is 4 pounds 9 ounces ) but they are to big for Jeter ( he is 2 pounds 12 ounces) I put his step in harness over the jacket to help hold it in place
I got Axl a new born size and that fits him he is 8 pounds. Also if you have a sewing machine then you can alter the preemie dresses into very cute doggy dresses
