There are about 900 breeds of sheep in the world.
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.
The sit for exam is a modified version of the Stand for Exam. It is generally used in novice level classes and requires the handler to order the dog to sit and then to move away from the dog the length of the leash. The judge will then approach the dog and pet the dog's head.
