The average lifespan of a Norwich Terrier is between 12 and 14 years.

Norwich terriers are only brown (or have a brown stripe down their back) and have thick wire hair. Cairn Terrier fur is light brown and can have a little black--usually around ears and nose/beard (others are all black), and is much softer and not as dense as a norwich terrier.

I have both, I think they have the same temperament, even though I find my Norwich male to be the most affectionate dog I have ever owned.

An interested, caring, and responsible family can adopt a Norwich Terrier, a popular breed of dog, from any local humane society or pet rescue center.
