=== Grooming === Norwich Terriers generally have small litters of 1 to 3 puppies. Generally, if a female is healthy, its optimal breeding period is between the ages of 2 (after all genetic health testing is complete - heart, eyes, hips and patellas) and six years. At seven years of age dogs are considered geriatric. The small supply and the high price of a purebred Norwich Terrier - often around US$4,500 in 2020 - has attracted fraud, as unsuspecting buyers pay full price for Cairn Terriers with docked tails, or mixed-breed puppies. The Norwich Terrier has two coats - a harsh, wiry topcoat and a soft warm undercoat. Ideally, the coat is combed  with a steel comb daily to once a week to remove the loose, dead hairs and prevent matting. Proper maintenance of the Norwich coat, like other hard wiry coats, requires 'stripping,' or pulling the oldest hairs from the coat (using fingers and/or a 'stripping knife,' a special grooming comb).
