In real estate the saying is "location, location, location." Regarding getting a Norwich terrier the saying is "timing, timing, timing". Norwich have small litters. The average litter size is two to three. There are only around 400 to 500 Norwich born in the United States each year. So it is not unusual to contact a breeder when they do not have any puppies or older dogs to sell. But if you are persistant and patient, you can get a Norwich terrier.
The best way to find a Norwich terrier is to individually ask breeders if they have any Norwich for sale. Try to be as specific as you can about what you are looking for - age, sex, color, etc. (See Some things to consider about Norwich terriers.)
I suggest you start with breeders who are members of the Norwich Terrier Club of America (NTCA). The NTCA web site has a "NTCA Breeders Directory". Not all members of the NTCA are breeders; nor do all member-breeders list themselves in the NTCA Breeders Directory.
Not all Norwich breeders have web pages, but many do. I maintain a list of web pages of Norwich breeders. Warning - not all breeders are reputable breeders. Buyer beware! Do your homework!
The American Kennel Club has an online Marketplace where breeders can list puppies that are available. Again - buyer beware, and do your homework.
Good Dog is a commercial marketplace that screens breeders.
I strongly urge you to avoid generic web sites that sell puppies. You are likely to get a Norwich that is not AKC registered ... or even worse, is not a purebred Norwich terrier.
