The Norwich is a small and smart Terrier, a great companion for children and tireless guard. It adapts well to life in the city, although it longs for the country, where it can play in the fields and hunting mice, etc. If it has been raised with a cat, they will get along; otherwise, it will want to chase them as well. These small Terriers enjoy the outdoors, and can run around and dig for hours. Their fearless nature and strong hunting instinct can easily lead them to trouble. For elderly people the Norwich and its cousin the Norfolk are delicious companions able to brighten the blackest of days.
As the Norwich and the Norfolk were considered the same breed until 1979, in the litters both types can emerge. These Norwich puppies are promising to entertain crowds and homes.
The size of the Norwich litters is usually small, four puppies or less. The weight at birth is about 140 g in average. The tail is docked (more or less to half the length) and the dewclaws removed during the first week. The Norwich grows and develops quickly. After eight weeks the weigh is at 1.5 kg; after six months, 5 kg. The ideal weight is between 6 and 7 kg. The erect ear characteristic should be raised after 10 to 12 weeks. The ears should drop and rise again during the dentition period. The maximum height is reached before a year. The Norwich puppies are extremely noisy and playful; they can even end their owner’s patience. It needs obedience training since it is small and plenty time to exercise. Adolescence is marked by the emerging of the adult rough coat. More hair care and “stripping” is necessary. The Norwich turns more serious and even calm with age.
The Norwich grows quite fast. The puppy is surprisingly strong and extroverted. The puppy weighs approx. 1.5 kg after eight weeks. 
The Norwich and Norfolk are closely related breeds. In fact, they were recently considered two separate breed. Sanitary information is similar for both breeds. An excellent health and relatively few serious hereditary diseases are breed qualities. In the Norwich C – section deliveries are frequent, not in the Norfolk. The largest concern for the owners is usually watching for injuries. The breeders mention skin problems as the largest health concern. Some allergic reactions have been reported (even to anti-parasite baths), and the owner should ensure an adequate diet (with essential fatty acids) and hygiene for their dogs. Hair care is relatively simple once the “stripping” is done properly, since only minimal grooming is necessary. The owner should inspect the eyes regularly for signs of injury or irritation. The most important thing is make it used to grooming sessions early, since this Terrier is tremendously independent and can strongly resist. It usually lives well past ten years.
