The Newfoundland (‘Newfie’) is a very large and heavy Mastiff type dog whose ancestors probably come from the polar regions. His sheer size means that he needs to live in a large house with a large garden and requires plenty of exercise. Many Newfies love water and are good swimmers. His coat is very thick and will need grooming daily. He is not usually aggressive but will warn if strangers approach the house. He has a shortened average lifespan of under 10 years.
Inbreeding coefficient – COI
(should be as low as possible)
The breed average COI is 6.1%
Effective population size (EPS) 276.27
EPS is a measure of how many individuals are contributing genetically to a breed population (KC registered dogs). It is a measure of the size of the gene pool in a breed. Lower than 100 is considered critical by conservation biologists and below 50 puts a breed at grave risk.
Health and welfare problems due to conformation
(body shape and physical characteristics)
- The overall shape of a Newfie is free from exaggerations but his sheer size and weightiness results in a much lower than average lifespan.
- Gastric bloat/torsion – stomach dilates with gas and can twist. Urgent vet attention required. Common in deep chested breeds.
- Medial canthal pocket syndrome (upper and lower lids inside the corner of the eye roll outwards creating a ‘pocket’ in which irritating substances such as dirt and dust can collect) Due to breed head shape.
BVA/KC Health Schemes http://www.bva.co.uk/chs
- Hip dysplasia (abnormality of the hip joints causing pain and disability): breed mean score 15.9 (parents should be lower)
- Elbow dysplasia (abnormality of elbow joint causing pain and disability) score should be as low as possible (ideally 0:0)
Estimated Breeding Values (EBVs) are now available for Hip Dysplasia http://www.thekennelclub.org.uk/about-ebvs/
DNA tests available
Parents should be tested for:
- Cystinuria (CU) (urate stones form in the bladder)
Unofficial (breed club) schemes
- Breed club Heart testing
- Bitches not to produce a litter under two years of age.
- Bitches over 7 years not to be bred
Ask the breeder to show you the certificates for the above tests/screening for both parents (or check the KC’s health test results finder). 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)
- Heart disease: Subaortic stenosis (fibrous ring develops below aortic valve – causes a heart murmur and may progress to heart failure; can also cause sudden death)

- Heart disease: Dilated cardiomyopathy (disease of heart muscle leading to heart failure)
- Heart disease: Mitral stenosis (thickened leaves of the mitral valve)
- Cancer: osteosarcoma (cancer of the bone)
- Ciliary dyskinesia (causes dogs to have recurrent respiratory infections)
- Atopic dermatitis (hypersensitivity to some pollens and other protein particles causing intense itching)
