Norwich Terrier

At a Glance

Temperament

Despite their diminutive size, Norwich Terriers pack the bold personality of their terrier ancestors with a fearless hunting spirit. These spirited little dogs can be barkers and diggers—traits inherited from centuries of rodent-hunting work—but consistent early training helps channel their energy productively. They're affectionate and engaging companions who don't seem to realize just how tiny they are, displaying the confidence and determination of much larger breeds.

History

The Norwich Terrier emerged in 1880s Cambridge, England, developed from a mix of Irish Terriers, Yorkshire Terriers, and local East Anglian red terriers (known as 'gypsy dogs'). Dog dealer Charles Lawrence bred these small hunters to control rodent populations, refining the breed through selective breeding. The breed gained recognition as one of the smallest working terriers, with the drop-eared variety eventually becoming the distinct Norfolk Terrier, while prick-eared dogs retained the Norwich name.

Health Notes

Norwich Terriers are predisposed to portosystemic shunt (7.41% incidence) and cataracts (4.02% prevalence), both significantly higher than mixed-breed dogs. Some suffer from a unique upper respiratory obstruction syndrome linked to a mutated ADAMTS3 gene; genetic testing is now helping breeders reduce this trait. The breed also faces labour complications, with over half of females requiring caesarean sections and a concerning stillbirth rate.
