Height runs 22–24 inches at the shoulder, against 28–32 in for the Great Dane and 15–17 in for the Boston Terrier. 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

Very low to moderate

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

Moderate to very high

The Great Dane rates moderate and the Boston Terrier very high; a puppy may lean either way.

Grooming

Low

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

Temperament

The Great Dane is usually described as friendly, patient, dependable. The Boston Terrier as friendly, bright, amusing. A mix can take after either parent or land in between. If you can, meet both parents of a puppy before you choose.
