Both breeds are extremely energetic, and their high energy means they require:
- Daily exercise
- Mental stimulation
- Tasks or training to curb destructive behaviors
Border Collies tend to be extremely intense and focused; their herding style is characterized by a fixed, hard stare (“strong eye”) and a low stalking posture, allowing very precise control of livestock.
Australian Shepherds are generally more playful and outgoing, and they herd sheep with a looser, more upright style — often driving stock with less reliance on the intense stare (sometimes using a bit of barking instead).
Aussie Sheperhds may not be the best choice for those without time for physical exercise and mental stimulation. Without this, they may develop destructive behaviors.
