The Bulldog, is not recognised in any colour not listed in the breed standard by the Kennel Club. For example Tri/ Black and White /Black /Blue/Lilac /Chocolate are all marked on their Pedigree as Unrecognised Colours.
The Kennel Club refuses to register Merle in this breed as it is known to have proven health issues. Unethical Breeders are promoting these colours as ‘RARE’ Don’t be fooled into purchasing one of these puppies and paying outrageously high prices.
Please find a reputable knowledgeable breeder who will help advise you in your hunt for a healthy Bulldog Puppy.
Look up Breed Club secretaries on this site who can help you contact breeders.
No responsible & ethical breeder will ever breed these colours intentionally.
KENNEL CLUB GUIDANCE FOR JUDGES FOR NRC IN BULLDOGS
“Judges are required to judge dogs against all elements of the breed standard, it is a balanced view. Judges cannot ask for a dog to be withdrawn due to colour – the term withdrawn relates to temperament and canine health and welfare issues (Regulation F(1)21o refers). Similarly a judge cannot exclude a dog from competition due to it having a nonstandard colour (Regulation F(1)21n refers). Colour is only one part of the breed standard and judges must judge dogs against all elements of the breed standard and then weigh up the merits of each dog and place accordingly. Of course awards can be withheld if there is a lack of sufficient merit in an exhibit and/or class and it is possible that reference to non-standard colour could be considered within this general term.”
