"A house without either a cat or a dog is the house of a scoundrel."
– Portuguese Proverb
Man's relationship with dogs and cats goes back to times of antiquity. Over the 12,000 years of domestication, man has selectively bred these species to meet specific purposes. Some were selectively bred to hunt, some to retrieve, and others were bred for human companionship. It is only natural that humans would want to showcase the talents of their beloved pets and working dogs. So the concept of dog and cat shows was formed to allow man's best friends to compete with one another in an effort to distinguish who had the best pet.
However, when shows were originally developed, not all dogs were "pets". In fact, most owners were showing off how well their dogs worked and boasted that their dog could beat other local working or hunting dogs. Performance was the first quality evaluated in competitions after which came competition for the "looks". Hunting and working dog contests were organized well before any conformation ring show, even though they were less official. Dogs with specific performance talents were bred to the same and great breeds were the result. At that time the breeders had to keep their own breeding records to insure the breeding of the traits they desired. Recording pedigrees started with the breeders.
The very first recorded conformation dog show was in Newcastle, England, in 1859. In America, interest in purebred conformation competition didn't take hold until after the Civil War. It wasn't until 1877 that the first Westminster Kennel Club Show took place. During this time, dog clubs for specific breeds and specific talents were becoming customary, such as hunting clubs (like hounds and gun dogs), and breed fancy clubs. Cat Fanciers caught the competition bug in the early 1900s. The very first cat shows in America were held in 1906.
The necessity for National Breed Dog Clubs or Breed Parent Clubs grew in importance, as there were more and more breeders and competitors every year. This provided the owners of specific breeds the avenue to communicate with one another, promote their breed, and gave the founding members of those clubs the opportunity to set the standards for their breed. With the concept of showing dogs growing all over the world, it became increasingly important to have uniform show rules, and to document the winnings and pedigrees of the top rated dogs for "many" different breeds. The year 1884 saw the development of the first all breed, purebred dog registry in America, The American Kennel Club, or AKC. The AKC works with National Breed Clubs, and other organized dog groups that will serve as the Parent Club for a breed, which will apply to the AKC (or other registry) for breed acceptance. The clubs must meet The AKC breed acceptance criteria before going into the miscellaneous group, after which it may move up to a permanent dog group with all criteria being met.
Different all breed registries were formed through out the world, each with different breed acceptance criteria based on their philosophies. The National Breed Clubs, Parent Clubs, or other organized groups, decide which registry works for their goals and locale. With any breed club's registry acceptance attempt, the "very important" breed standards have to be detailed, and its format and information have to be accepted by the registry. Three are some exceptions such as the UKC, which actually sets the breed standard based on the input of that breed's professionals and original function of the dog. All breed registries will differ somewhat with what they want to see in the breed standards, but not necessarily the actual wording. Formalizing a breed standard can be a very political event. The decisions made will affect the breed forever, be it good or bad.
There are breeds that end up with two clubs who disagree on breed function, or breed standards, and choose to register their breed with different registries. The breed standard set for a specific breed with the AKC may not be the same as with the UKC, not only because the registries may differ in their criteria, but also because more than one breed club may have existed, thereby creating two different breed philosophies of form and function. One club (be it National Breed Club or organized fancy group) may have divided and chosen different paths, such as with the famous Jack Russell Terrier also known as the Parson Russell Terrier, depending on to which registry your referring.
