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

Height runs 21–22 inches at the shoulder, against 14–15 in for the English Bulldog 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.

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

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

Trainability

Moderate

The English Bulldog rates moderate and the Mastiff moderate; a puppy may lean either way.

Grooming

Very low to moderate

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

Temperament

The English Bulldog is usually described as friendly, courageous, calm. 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.
