The Norfolk Terrier is a short legged and compact little dog, typically with a delightfully cheerful and ‘gutsy’ disposition. Apparently once used on farms to catch rats, he is now a great little companion dog. His dwelling does not need to be large, but he would prefer to have a garden and be given plenty of opportunity to explore. Although small he does need daily exercise. His medium length coat will need frequent grooming to keep it looking its best.
Inbreeding Coefficient - COI
(Should be as low as possible)
The UK Kennel Club breed average COI is 13.7% - 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.
Health and Welfare Problems due to Conformation
(Body shape and physical characteristics)
Estimated Breeding Values (EBVs) are now available for Hip Dysplasia and Elbow Dysplasia:
DNA Tests Available
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)
- Patellar luxation (slipping kneecap)
- Heart disease: Mitral valve disease (degeneration of the valve leading to heart failure)
- Coloboma (optic nerve defect – a fissure in the eye – effect on sight varies)
- Lens luxation (dislocation of the lens)
- Muscular dystrophy
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.
