Kaika! The Australian Shepherd is very smart. My favorite aunt and uncle have one. Wondering if you could show us a picture of the puppy!
I know they do shed quite a bit, and have a thick undercoat as well.
I hope you get to keep her!
My aunt's Aussie does lots of tricks with the frisbee, and knows so many words that they have to spell some words they don't want her to hear!
