I have to agree with most who said she does look like a dwarf. Having one of my own ...... I know, full well, just how adorable they can be.
And your little girl is as adorable as they come!
As for movement....don't let anyone tell you that dwarfs can't "move". There are many exceptions. Our "little girl", who is a yearling now & only 20" tall...can strut with the best of them. She flips her tail over her back & flags it high & proud as she picks up those little legs & prances around with a hesitating trot you would only expect to see on much bigger, refined, "normal" mini. Here is a Christmas card I did up for her, showing some action photos.
I don't think it will take very long for you to realize just how "blessed" you are to have your special little girl....and you will know exactly what I mean the longer you have her. They have a very unique personality & a way of wrapping themselves around your heart very quickly!
