Australian Shepherds are easy-going, remaining puppy-like even in their adult years. This courageous dog makes a good watchdog for the home. Aussies are excellent with children, even with an active child, as they love to play. They are devoted, loyal friends and guardians, for they are naturally protective. Affectionate, very lively, agile and attentive—they are eager to please, with a sixth sense about what the owner wants. Australian Shepherds are highly intelligent and easy to train. Though aggressive when at work with livestock, the Aussie is gentle with human friends. Australian Shepherds are not the kind of dog to lie around the living room all day or live happily in the backyard with only a 15-minute walk. They need much more exercise than that and something to occupy their mind daily. Socialize well to prevent them from becoming suspicious of strangers. Working lines may be too energetic for people who only have a moderately active lifestyle. Some like to nip people’s heels in an attempt to herd them, and this behavior needs to be corrected, teaching the dog that humans are not to be herded. The Aussie is a quiet worker. This breed is not usually dog aggressive.
