So let's address the ago old QUESTION,  where does Merle come from? Is it part of the breed and why are we just noticing it now ?

ANSWER:The Merle Genetic is a pattern associated with all dog breeds and most animals domestic or wild, it is sometimes assigned or referred to under different terms/names (ie.)cow patched, patchwork, partied, brindle, spotted, dapple, roan, harlequin, merlequin, mottled, splotched, blotched, salt & paper ect.)  sometimes confused with ticking which it is not , but non the less there are "Merle Ticked Dogs". - "Merle Genetic' is a diluting gene that will lighten the base coat of any dog it is bred to while producing a broken pattern of color/s over the entire coat and eye color. The patches can be any shape or size and can be located anywhere, unlike the patches on a piebald dog (which are generally spherical yet confined to the head and body starting above or behind the shoulders and that are crowned with white as seen in a cow's pattern ). The edges of merle patching may appear jagged/ruff or torn. The M locus is the home of the merle allele. Merle is dominant, and so denoted by the capital letter M. Merle is pretty unique because all normal merles are heterozygous (M) or (m lowercase m). A homozygous merle is actually a double merle(MM) that may or may not carry an Albino trait/(most do). Merle affects only eumelanin pigment containing melanin. That means that any black, liver, blue or isabella/(greyish-yellow color) in the coat, eyes or nose can also be merled, whether it's the whole of the body, a mask on a sable/red, shading, brindle stripes, or even a saddle or smut color pattern. Phaeomelanin (red) is not nearly affected as much and sometimes will appear as a normal red coat color displaying permanent faint merle patterns\A.k.a Ghost Merle, you may also experience dark red merle pattern or spotting on the top of lighter red, fawn or champagne pups when newly born or delivered and may carry the pattern on it's coat temporary only too fade away with age and time\A.k.a Phantom Merle. This type of dog is still merle just un-NOTICEABLE to the untrained eye. The severe inbreeding/linebreeding of merle dogs is not encouraged and prohibited by the registry due to the chance of creating extreme cases of; lack of pigment in certain vital areas of the animal (ie.) the eyes and inner ear hair. Most heterozygous merles have plenty of pigment because they still have an m (non-merle) allele to help them to create pigmentation melanin in the inner ears and eyes.  a simple visual examination of a dog or pups head, eyes and inner ears can tell alot about the amount or "lack of" pigmentation in those vital areas, too ensure dark pigmentation for a healthy merle pup or litter locus testing is always advised. - " EVEN THOUGH THE GENETICALLY bred MERLE PUPPIES IN THE PICTURE BELOW ARE 80% ALL WHITE THEY CAN STILL HEAR, SEE AND FUNCTION NORMALLY , BECAUSE OF THE PRESENT MELANIN of HEAD PIGMENTATION " - This is a very important requirement for the production of a healthy merle litter verses an un-healthy merle litter which may consist of 100% All White Albino Genoytpe Pups. Merle Genetics have always been a part of the BULLDOG/PITBULL and bull baiting breedtypes both Bully or Terrier VARIETIES and always will be. Merle Genes/traits  are a pattern that occurs in all breeds and cannot be simply removed or culled from a breed due to its Dominant traits that have the ability to hide its-self or become\act and perform as a recessive gene would for many years before re-occurring modifying and mutating into the beautiful color\pattern morphs we call MERLE.

Example of a Merle American Bully pup who does not display any merle pattern on her coat but does carry the genetic merle trait .

Above is an excellent example of a Clean and Correct Black\Blue\White & Merle\Pied Pattern "Classic American Bully" produced and owned by Blueswaggerline Kennels.

John P. Colby pictured above with "Goldie" a RED MERLE APBT who was also pregnant in this photo at the time it was taken. John is smiling in this photo an was always very proud of his Merle APBT "Goldie" as should we all be of our very own living legends within the merle area the breed and #Merlemovement.

Even though we do not put emphasis on dogs weight or size for registration overall, we will recognize all styles and classes of APBT or Am.Bully according to CBR Standard  (ie.) Standard,Pockets, Extremes,  Classic, Exotics, Micros, & XL's . We have additionally incorporated a newer classification for the massive in size which will include the  XXL  with merle genetic trait fitting Creole Bully class or standard types.  Any dog in excess of 165lbs. or more will be considered XXL type under the Creole Bully Breed.
