I've checked yesterday with a local GSD breeder/exhibitor & there are no rules under which a non standard coat colour cannot be shown in
the UK, apparently under the rules for European shows are different & non standard coat colours are a disqualifying fault. There are no longer non standard coat lengths, but all dogs must have a correct undercoat as not having a correct under coat is also a disqualifying fault on the continent not only for
showing but also for registration &
breedingUK:-
<Faults Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded should be in exact proportion to its degree and its effect upon the health and welfare of the dog and on the dog's ability to perform its traditional work>
Europe: -
<Colours are black with reddish-brown, brown and yellow to light grey markings; single-coloured black, grey with darker shading, black saddle and mask. Unobtrusive, small white marks on chest as well as very light colour on insides are permissible, but not desirable. The tip of the nose must be black in all colours. Dogs with lack of mask, light to piercing eye colour, as well as with light to whitish markings on the chest and the insides, pale nails and red tip of tail are considered to be lacking in pigmentation. The undercoat shows a light greyish tone. The colour white is not allowed.>
<Dogs with
eliminating faults such as e.g. unsound temperament, congenital deafness or blindness, hare-lip, cleft palate, substantial dental defects or jaw anomalies, PRA, epilepsy, cryptorchidism, monorchidism, albinism,
improper coat colours or diagnosed severe hip dysplasia may not be bred.>
