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

Height runs 22–24 inches at the shoulder, against 17–19 in for the Pit Bull and 27.5–30 in for the Mastiff. 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.

Pit bull is a type, not one AKC breed. Size figures use the American Staffordshire Terrier standard.

Coat, energy and training

Shedding

Low

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

Energy

Moderate

Daily walks and some play are enough for most of these dogs.

Trainability

Moderate

The Pit Bull rates moderate and the Mastiff moderate; a puppy may lean either way.

Grooming

Very low

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

Temperament

The Pit Bull is usually described as confident, smart, good-natured. The Mastiff as courageous, dignified, good-natured. A mix can take after either parent or land in between. If you can, meet both parents of a puppy before you choose.
