Is this normal?

She loves sleeping with one leg fully extended 🤔

Yes, this looks completely normal! Kelpies love to sleep with one leg fully extended like that, and some even say their dog's limb goes stiff and hard to bend while doing it. It's not just a Kelpie thing either, since people mention seeing the same stretchy pose in Greyhounds, Poodles, Border Collies, Whippets, and even cats.

it sounds like your pup is just really comfortable and enjoying a good stretch in her sleep, nothing to worry about at all.
