About the breed
Australian Shepherd
The Australian Shepherd is a brilliant, high-drive herding dog — devoted, energetic, and always ready to work. Aussies are reasonably long-lived for their size and stay active for years.
Care basics
Caring for a Australian Shepherd
Exercise and work. An Aussie needs a job. Without intense daily exercise and mental challenge it becomes anxious and destructive.
Mental stimulation. One of the smartest breeds — training, agility, and puzzles are not optional.
Senior years. Aussies often stay active late. Around age 9 to 10, scale activity to keep an aging Aussie comfortable.
