All Dog Breeds >>Health of Norfolk Terrier
The life expectancy of a Norfolk Terrier is 12–15 years, with some growing as old as 19 years. Norfolks do have incidences of mitral valve disease, luxating patellas, and incorrect bites (where the teeth do not align with the breed standard, i.e. overshot or undershot). Norfolks most often have shallow hip sockets and many breedlines are dysplastic. There has never been a Norfolk Terrier recognized by the Orthopedic Foundation for Animals (OFA) as having "excellent" rated hips.
Therefore responsible breeders are testing for hip dysplasia. Breeders that do not radiograph hips and have them evaluated by either OFA or PennHip, cannot answer questions regarding hip dysplasia in their breeding program. Norfolks generally have small litters. Responsible breeders only breed healthy dogs who are of good temperament, good pedigree lineage and best reflect the breed standard. The demand for Norfolk is far greater than the supply.
The environment in which they are raised directly impacts the temperament of the puppy for its lifetime.
