The Miniature Australian Shepherd was developed to be a small to moderate sized, intelligent, all-purpose stock dog of great character and endurance.  Many MASs today do the work they were bred for, and even those that have never seen sheep or cattle usually have a strong herding instinct.  This means that MASs need fenced yards and leashes, as the temptation to herd dogs, children, and traffic can simply overwhelm them.

Being bred as a working dog means that most MASs are not content to be couch potatoes, although each dog has an individual character and therefor some are more sedate and quiet-natured than others.  For the most part, however, these are high energy dogs who need a purpose in their lives-a job as it were.   Owners must be committed to give these dogs the time and attention they require through play and training, for as with any dog, undirected energy can turn towards destructive behaviors such as digging and chewing.  Running, jumping, and rough-housing are all a part of being a normal Aussie.

Obedience training is highly recommended as a means of teaching owners how to channel the typical Aussie's innate desire to please into appropriate behaviors.  MASs learn very quickly, so be certain you are willing to keep your dog occupied with walks, play, and training to benefit both mind and body.

Although many MASs are friendly with everyone, the breed tends to be somewhat reserved and cautious around strangers. With dogs of this nature, owners should encourage the dog to meet people but not force encounters.  MASs are often quite protective of their family and property, a desirable trait in some situations but not acceptable in others, and some dogs never accept strangers.  As with all dogs, poor socialization may become aggressive without proper training.

MASs are generally healthy dogs and can be expected to live up to 12 years or more, so ownership can be a lengthy commitment. Although minimal, there is some grooming required to keep the coat clean and conditioned, such as regular brushing and nail trimming. To maintain their high energy levels, typical active MASs may eat more than other more sedate dogs of similar size, so be prepared to feed plenty of high quality food.
