The Norwich Terrier is one of the smallest working terriers — around 10 inches tall and roughly 11-12 pounds — a stocky, hard-coated little dog with prick ears that distinguish it from its drop-eared near-twin, the Norfolk Terrier. It looks like a soft companion lapdog and is sold as one, but the wiring underneath is a fearless ratting earth dog. Norwich are confident, busy, sometimes bossy, and they bond hard to their people, equally happy to play fetch for an hour or sleep in your lap afterward. They are one of the more biddable and people-oriented terriers, which makes them a popular choice — but they are still a terrier, with the prey drive, the digging instinct, and the bark to prove it. The practical headline for this breed is health, not behavior. The Norwich Terrier has a recognized, serious breed-specific problem with breathing — Upper Airway Syndrome (UAS) — that the breed's own parent club has flagged as a research priority because there is no screening test for it. Any honest Norwich profile has to lead with that, because it is the single biggest hidden cost and decision factor in the breed, not coat or exercise. Day to day, the Norwich is manageable: 30-60 minutes of daily exercise plus play and training suits it, and it adapts well to apartments and to families with older children. It is alert and will bark at arrivals, but it is not typically a chronic nuisance barker like some terriers if exercised. Who the Norwich is right for: an owner who wants a sturdy, affectionate, adaptable small companion with terrier spark, and who will buy from a CHIC-screened breeder and accept the breed's airway and cost realities. Who it is wrong for: bargain buyers (the breed is expensive and litters are small), anyone who cannot tolerate a dog that may need airway management, and households with free-roaming small pets. Decide on the airway risk and the price, not the cute face.

The Norwich Terrier originated in East Anglia, England, in the late 1800s and early 1900s, bred from small working ratting terriers kept by farmers and, famously, popular as ratters and mascots among Cambridge University students (the breed was once nicknamed the 'Trumpington Terrier' after a Cambridge street). It was developed to bolt and kill vermin, hunt rats around stables and barns, and work in packs alongside larger hunting hounds — jobs th…

Norwich Terrier day-to-day care is light; the care that matters is monitoring for the breed's airway problem and managing the coat. Breathing surveillance: this is the single most important care task. Watch for noisy breathing, snorting, exercise or heat intolerance, gagging, or laboured breathing — these can signal Upper Airway Syndrome, which has no screening test and ranges from mild to surgical. Keep the dog lean, avoid heat and over-exertion, use a harness not a neck collar, and raise any new breathing noise with a vet promptly rather than dismissing it as 'just a small-dog thing.' Coat: a hard, wiry double coat that is hand-stripped every 8-12 weeks to keep texture and weather resistance; clipping softens and fades it. Between strippings, brush weekly. Shedding is low. Budget for stripping as a skill or a recurring groomer cost. Exercise: 30-60 minutes a day of walking plus play and training. Enough to satisfy a busy terrier brain, not so much that an airway-compromised dog overheats — moderate and consistent beats intense. Prey drive and containment: genuine ratting instinct. Secure, dig-proof fencing and a leash near roads and wildlife; do not trust recall around small fleeing animals. Weight: keep two ribs easily felt — extra weight directly worsens airway function and patellar strain. Weigh monthly; adjust portions 10% and recheck in four weeks. Decision rule: if a Norwich shows persistent noisy breathing, blue-tinged gums, collapse, or severe distress in heat or exercise, treat it as an emergency — airway crises in this breed escalate fast and are far cheaper to manage early than after a collapse.
