The terrier breeds originated in Great Britain and Ireland. These feisty, energetic dogs were bred to help control vermin, rabbits, fox, badgers, river rats, and otters. The word terrier is derived from the Latin Terra, meaning earth, because they work as well underground as they do above ground, and in the water. Although they are not used as widely for controlling vermin or hunting as their ancestors, these dogs still show their attitude and willingness to engage in a spirited “argument”. These dogs may range from rather small to large in size and are all known to be bundles of energy. Terriers make great companions to the owner ready for a dog with lively characteristics.
