Additional information (Wiki): These small but hardy dogs are courageous, remarkably intelligent and wonderfully affectionate. They can be assertive but it is not typical for them to be aggressive, quarrelsome or shy. They are energetic and thrive on an active life. They are eager to please but have definite minds of their own. They are sensitive to scolding but 100% Terrier. They should never be kept outside or in a kennel setting because they love the companionship of their owners too much. Norwich are not given to unnecessary barking but they will warn of a stranger approaching. Norwich are good with children. If introduced to other household pets as a puppy they generally co-habit peacefully, though caution should be observed around rodent pets as they may be mistaken for prey.

Norwich Terriers are hardy, active dogs, bred for a working life of pursuing vermin and accompanying their farmer owners on horseback. A good daily walk is therefore the minimum needed to meet the exercise requirements of a healthy Norwich Terrier. They are excellent walking companions. They are reasonable joggers for those who like to jog with their dogs, and with appropriate training can even accompany mountain bikes off-lead. Norwich Terriers compete in Earthdog competitions, and are increasingly common in Agility and Flyball competitions. (Note: US trials are a play trials staged on caged rats. In Europe a real foe, live fox is used). Note that these dogs were bred as working terriers, and thrive best with at least one hour of real activity daily, such as a good walk, run, or working session. Norwich are curious, independent dogs who may become bored by routine, repetitive walks/routes; they need more than access to a backyard for their physical and mental health. While these dogs are the smallest of the working terriers, they are not lapdogs and should emphatically NOT be confused with the toy breeds, which do not have the same need for activity, stimulation, and exercise.
