Pounds. The dark band is where most Mastiff Blue Heeler Mix dogs end up; the light band is the full range between the smallest and largest parent.

Height runs 22–25 inches at the shoulder, against 27.5–30 in for the Mastiff and 17–20 in for the Blue Heeler. The parents differ a lot in size, so litters vary more than usual. Breeders normally use the larger breed as the mother to keep whelping safe.

Coat, energy and training

Shedding

Low to high

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

Energy

Moderate to very 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 low to moderate

The Mastiff rates moderate and the Blue Heeler very low; a puppy may lean either way.

Grooming

Very low

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

Temperament

The Mastiff is usually described as courageous, dignified, good-natured. The Blue Heeler as alert, curious, pleasant. A mix can take after either parent or land in between. If you can, meet both parents of a puppy before you choose.
