Looks like a beautiful pup!
Never had one, but known several over the years.
They strike me as very energetic, protective, smart, and loyal. It's in their genes.
A couple I've known have been great "people" dogs, a couple hesitant to strangers (good thing), and a couple just plain nasty to everybody, including the owners.
Obviously, it's all in their up-bringing.
Like a Beagle and scent-hunting; those genetics are strong with an Aussie's herding and protection. Good dogs when properly trained.
We've had Boxer's for a while. Not herders, but can be a little hard-headed sometimes, real goofy others, but always protective of his Mom.....
I like that, even when he's barking at me!
