The breed standard offers a distinct picture in words, which outlines the ideal size, weight, colour, length of coat, tail structure, temperament and movement for each of the 175 dog breeds recognized by the Canadian Kennel Club. Each breed's parent club creates the standard, which acknowledges the primary characteristics related to the function that the dog was bred to perform, whether it be tracking game, herding livestock or hunting vermin. The CKC orders each breed into one of seven groups, which also serves to identify the function that those dogs were bred to perform and categorizes the breeds into a logical structure for shows and trials. A conformation dog show tests how closely a dog conforms to the breed standard. So, in essence, the various entries in a dog show, whether they are a Chihuahua, a Labrador or a Wolfhound, are not only competing against each other, they are in a contest with their own breed standard.
