Pounds. The dark band is where most Border Collie Saint Bernard Mix dogs end up; the light band is the full range between the smallest and largest parent.

Height runs 22–26 inches at the shoulder, against 18–22 in for the Border Collie and 26–30 in for the Saint Bernard. 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

Moderate

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 to very high

The Border Collie rates very high and the Saint Bernard moderate; a puppy may lean either way.

Grooming

Moderate

Brush a couple of times a week.

Temperament

The Border Collie is usually described as affectionate, smart, energetic. The Saint Bernard as playful, charming, inquisitive. A mix can take after either parent or land in between. If you can, meet both parents of a puppy before you choose.
