A specialty show is a dog show which reviews a single breed, unlike other dog shows, particularly conformation shows, which are generally referred to as "all-breed" because they are open to all breeds recognized by the sponsoring kennel club.
A specialty show may be regional or national. A "Best in Show" win at a national specialty show is tremendously prestigious, indicating that the winning dog or bitch triumphed at a contest which attracted entries from the most serious fanciers of that breed in the country or continent. Some specialty shows attract international entries.
Examples of specialty shows include:
