Coat, energy and training

Shedding

Very low to moderate

Neither parent has a low-shedding coat, so expect dog hair around the house and seasonal heavy shedding.

Energy

High

Plan on long daily walks plus real exercise, such as running, fetch or a sport. A yard alone will not tire this dog out.

Trainability

Very high

The Australian Shepherd rates very high and the Boston Terrier very high; a puppy may lean either way.

Grooming

Low

A weekly brush and the odd bath keep the coat in shape.

Temperament

The Australian Shepherd is usually described as smart, work-oriented, exuberant. The Boston Terrier as friendly, bright, amusing. A mix can take after either parent or land in between. If you can, meet both parents of a puppy before you choose.
