aww she's adorable!!! I'm partial to topknots...and my girls hair grows so slooooooooowly!!! ugh I love the long look on top...but with that look you have to always have her hair up...you might talk to your groomer she might have some suggestions...I prefer daizy's back to be short and her legs and face longer...too...plus it's a LOT easier to brush and keep her from looking so messy...right after she gets groomed!
And since Lexi's leg hair is so long...that cut would probably look super cute on her..legs and face long...and her back cut short....jmo.
