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

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

Very high

The Border Collie rates very high and the Boston Terrier very high; 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 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.
