I, too, think she looks like she has Border Collie in her, but then again, you never know with pups. They may look one way as pups, and grow up into something completely different as adults!

I have a friend who was told her dog was a purebred Australian Shepherd when she got it. This is what her "purebred" Aussie looks like now:

Notice the ridged back...

Whatever your pup is... CONGRATS!!!! She's a beauty!!

As for names.. I've always loved Hawaiian names..
Nani = Beauty or Beautiful
Kahi = One.. because she's the one for you
Hauoli = Happy
Kina'ole = Perfect.. nickname could be Kina or something
Lilia = Lily (like the flower) (my sister's name is Lilija, pronounced the same as Lilia ; it's a beautiful name)
Mahina = Moon
Lani = Sky
Hoku = Star
Pepe = Baby
Anela = Angel
Okay I'm going to stop now or else I'll be going on forever.
