That's a toughy! I'm not sure what to tell you since she is both cotton AND silky - but I CAN tell you that I LOVE the "all cotton" coats shorter. If either of my babies had a cotton coat, they would DEFINITELY be cut short as I personally love that look with the cotton coats. The short cuts on them always look so "puppy-ish"
If you ask me though, I think - ok nevermind - I KNOW Maggie would look cute either way, short OR long hair!
