The Norwich Terrier closely resembles the Norfolk Terrier except that his ears stand up. His small size means that he will adapt to most home environments, although being a Terrier he would appreciate a garden. He is a sturdy little dog who should have daily exercise. His coat is medium length, thick and coarse and should be groomed regularly.
Inbreeding Coefficient - COI
(Should be as low as possible)
The UK Kennel Club breed average COI is 8.1% - see 'A Beginners Guide to COI'
Effective Population Size - EPS46.20
EPS is a measure of how many individuals are contributing genetically to a breed population. It is a measure of the size of the gene pool in a breed. Lower than 100 is considered critical by conservationists and below 50 brings a breed close to extinction. For more information see the Kennel Club article.

Unofficial (Breed Club) Schemes
Ask the breeder to show you the certificates for the above tests/screening for both parents. If any of the above tests have not been considered necessary by the breeder (and there may be good reasons), ask her to explain why.
Other Diseases Reported
(For which there are currently no genetic or screening tests for sire or dam)
- Lens luxation (the lens of the eye is displaced into an abnormal position)
- Epileptoid cramping syndrome (muscle spasms and loss of control with varying degrees of severity and frequency)
- Upper airway syndrome (elongated soft palate and other changes)
- Patellar luxation (dislocated knee joint)
- Heart disease – cardiac murmurs are present in some Norwich Terriers and can sometimes lead to heart failure.
Ask the breeder about the medical history of the parents, grandparents and great grandparents. Consider carefully whether to purchase a puppy if some of these or other diseases are in the family line.
Ask about the breeder’s policy in cases of serious genetic diseases occurring to your puppy in later life. Good breeders will request to be informed of such events in order to improve future breeding decisions. Some breeders will also agree to contribute towards medical costs or refund purchase price.
