Norwich Terrier

The Norwich Terrier is a toy-sized dog belonging to the Terrier Group. The breed traces its roots to England. AKC registration statistics place it at #104 in popularity. Adults typically stand 9–10 inches (23.4–25.4 cm) at the shoulder and weigh 9–12 pounds (4.3–5.4 kg), with males at the upper end of those ranges.

Published breed data puts a typical Norwich Terrier lifespan at 12–15 years. The main levers behind that number are body size (smaller dogs usually outlive bigger ones), genetics, and how consistently a dog stays lean, exercised and current on preventive veterinary care. Against the average dog, toy-sized breeds like this one sit on the longer-lived end of the spectrum. Individual lifespans vary widely with genetics, body condition, preventive care and disease; published ranges describe populations, not predictions for one dog.

Energy is moderate: a daily walk plus some playtime keeps most of these dogs content. Trainability is average — consistent, reward-based sessions work well. With socialization, children and this breed get along well; supervise the early years. Other dogs are usually accepted, particularly with early socialization.

Medium-sized homes suit this breed fine; true apartments depend on the dog and the schedule. Twice a year the coat blows noticeably, and the rest of the year shedding stays tolerable. Grooming is moderate, with regular brushing and periodic baths keeping the coat healthy. No low-shedding claim applies here. Allergy sufferers should spend time with the breed before committing.

Two numbers on this page earn their keep more than the rest: 4.9 kg of average adult weight (heavier than 10% of the 153 breeds catalogued here) and a 12–15 year expected lifespan. Insurance pricing leans on exactly these figures, which is why comparing plans early, before any condition becomes pre-existing, is the standard advice for this breed. Feeding portions, crate sizing and first-year costs below all start from the same AKC-sourced numbers as this page.
