What is a Breed Standard:
A Breed Standard is a written 'blueprint' of a Standard of perfection for a Breed. It outlines the physical characteristics and temperament qualities to which a breeder strives to achieve in their breeding program. The Standard outlines correct structure, movement, coat type, colour and many other physical attributes specific to the Breed. It also describes the appropriate temperament that is expected and what role the Breed was bred to fulfill, ie guarding, herding etc. The Standard also outlines what is not allowed for in the Breed, under two categories, Faults - which are not preferred - and Disqualifications - which should exclude the dog from both the Breed Ring and a Breeding program.
The role of the Judge:
The Judge's role is to compare each dog to the Breed Standard. They are not to attempt to visualize how the dog may mature but are to judge the dog as it appears before them 'on that day.' When competing against another exhibit (which is what a dog is called when competing), they are to be graded against the Standard and placed in the position of quality as interpreted by the Judge. How the Judge interprets the dog's quality can also be influenced, positively or negatively, by the way in which the dog is presented to them (the handling) and the quality of the presentation (the grooming).
The role of the Exhibitor:
The physical and temperament qualities of the dog can be enhanced or detracted from by the abilities of the exhibitor or handler (the person showing the dog) and the quality of grooming (each breed has a specific grooming process).
Exhibitors can be owners, breeder/owners, professional handlers, and Junior Handlers and it is their role not only to learn how to groom their dogs but to know the movement that is appropriate to their Breed as laid out in their Breed Standard under "Gait".
