Early, consistent training will help produce a directed, yet spirited, companion. Although some tolerant individuals provide great companionship for children with their playfulness and high energy level, in general, close supervision with children is advised for all terriers. Not all terriers are equally feisty. Among the easiest to live with are the Soft-Coated Wheaten and Airedale, along with some Cairn Terriers. The hardest may be the Fox, the Jack Russell, and the Bull Terriers.
All terriers require a commitment to training and discipline.
Without it, they will become bossy and snappy. With proper direction, they can be playful and spirited companions.
