My sister has a PM #12 named Amy, and she sheds horribly! I gave her a little trim to even things out, but her hair is really bad. I have a #20 and her hair is just fine, and we got them at the same time (1996).
Here's a picture of Amy and Josefina.
My girls: PM Felicity, PM Kirsten, Samantha, Rebecca, PM Molly, Jess, Mara (#8), Shannon (#15), Marjorie (#20), Margie (#21), Dawn (#27)
