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 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

Moderate

The Mastiff rates moderate and the Catahoula Leopard Dog 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 Catahoula Leopard Dog as loyal, independent, watchful. A mix can take after either parent or land in between. If you can, meet both parents of a puppy before you choose.
