A Breed Standard is the guideline which
describes the ideal characteristics, temperament and appearance including the
correct colour of a breed and ensures
that the breed is fit for function.
Absolute soundness is essential.
Breeders and judges should at all times
be careful to avoid obvious conditions
or exaggerations which would be
detrimental in any way to the health,
welfare or soundness of this breed. From
time to time certain conditions or
exaggerations may be considered to have
the potential to affect dogs in some
breeds adversely, and judges and
breeders are requested to refer to the
Breed Watch section of the Kennel Club
details of any such current issues. If a
feature or quality is desirable it
should only be present in the right
measure. However if a dog possesses a
feature, characteristic or colour
described as undesirable or highly
undesirable it is strongly recommended
that it should not be rewarded in the
