i really have no advice but she is a DOLL!! I agree...don't let them cut the hair on her head or muzzle...I have regretted cutting the muzzle. no i am having a hard time letting it grow because i can't stand that phase where it is sticking straight up everywhere.
anyway, I would just tell them to "trim" it a tad to even it out, if you think it needs it. just make sure and stress to them what you DO NOT want.
good luck and please send pics
