Coat, energy and training

Shedding

Low to very high

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

High

The Bernese Mountain Dog rates high 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 Bernese Mountain Dog is usually described as good-natured, calm, strong. 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.
