Australian Shepherds sind sehr aktive und arbeitseifrige Hunde. Sie brauchen aktive und erfahrene Hundehalter, die das richtige Maß zwischen Auslastung und Ruhe finden. Auch für diese Welpen gilt: Ruhetraining ist wichtiger als Beschäftigung, diese wird allerdings mit zunehmendem Alter wichtiger. Bei der Verpaarung sollte auf den Merle-Faktor geachtet werden, da gesundheitliche Probleme damit einhergehen können.
