Blue merle Border Collie puppy Red merle Australian Shepherd. Merle is a genetic pattern in a dog's coat and alleles of the PMEL gene. It results in different colors and patterns and can affect any coats. The allele creates mottled patches of color in a solid or piebald coat, blue or odd-colored eyes, and can affect skin pigment as well. Two ...
[4] [3] The breed is known for its unique colorations and variable coat patterns, it being said no two dogs sharing a coat. [3] The breed standard allows for blue merle, red merle, solid black or solid red, with or without white markings and with or without tan points. [6]
Blue eyes on Great Danes are “permitted” by the breed standard in dogs with merle patterns or harlequin coats, a stunning black and white cow-like print. Otherwise, most Danes have dark eyes ...
The merle gene does not normally affect the entire coat of the dog, but dilutes the color only in areas that randomly present the characteristic of the gene. Deeper colors are preferred; predominantly white coats are discouraged. Since Catahoula is a working dog, coat color is not a primary consideration. [1] [6]
Erect ears, short fur, black, red, black-and-tan or merle, often with some white on neck or over shoulders. (Note: the name "German Collie" is also applied to a cross between a German Shepherd and a Border Collie.) Huntaway Developed in New Zealand from a mixture of breeds, probably including some collie – but it is not of the collie type ...
The second way blue eyes can appear is when a dog has a lot of white fur on the face. Since the white areas cannot produce any pigment, pigment from the eyes and nose may be lost as well. [68] The third way is when dogs are affected by albinism. [68] A different gene, unaffected by coat color, can make the eyes blue. However, this gene is rare.
The breeding of two Merle dogs runs a high risk (in all breeds) of sight and hearing defects in the offspring. As a “solid” (dog not showing the Merle pattern) may still genetically be a Merle, it is vital to perform a full DNA Merle sequence test to determine the “lengths” of Merle in each dog so that the safest breeding practices are ...
The Old English Sheepdog is a large breed of dog that emerged in England from early types of herding dog. Other names for the breed include Shepherd's Dog and bob-tailed sheep-dog. [1] The nickname Bob-tail (or Bobtail) originates from how dogs of the breed traditionally had their tails docked. Old English Sheepdogs can grow very long coats ...
