Here’s there breakdown in no particular order
1. The Schipperke

Bred as a watch dog, good in small spaces, loves killing rats, and needs more training than most dogs.
2. The Australian Shepherd

Bred as a herder, eager, and needs agility training.
3. The Blue Heeler

Needs to be ran, rugged coat, and nippy without training.

I hope this helps someone out there make a wise choice.
