A Labrador exhibiting a yellow coat colour. Domestic dogs exhibit diverse coat colours and patterns.In many mammals, different colour patterns are the result of the regulation of the Agouti gene, which can cause hair follicles to switch from making black or brown pigments to yellow or nearly white pigments.
Labrador Retrievers are a popular dog breed in many countries. There are three recognised colours, black, chocolate, and yellow, [1] that result from the interplay among genes that direct production and expression of two pigments, eumelanin (brown or black pigment) and pheomelanin (yellow to red pigment), in the fur and skin of the dog.
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.
Merle is a distinguishing marking of several breeds, particularly the Australian Shepherd and Catahoula Leopard Dog, and appears in others, including the Miniature American Shepherd, the Koolie in Australia, the Shetland Sheepdog, various collie breeds, the Cardigan Welsh Corgi, the Pyrenean Shepherd and the Bergamasco Shepherd.

When you take your dog to the vet, the fur around the affected area may be clipped, and the skin will be cleaned. The vet might recommend antibiotics, pain relief, or ongoing topical treatments. 4.
One version produces yellow dogs, and a mutation produces black. All dog coat colors are modifications of black or yellow. [2] For example, the white in white miniature schnauzers is a cream color, not albinism (a genotype of e/e at MC1R.) Today, dogs exhibit a diverse array of fur coats, including dogs without fur, such as the Mexican Hairless ...
At first glance, they may look the same but white dogs and albino dogs are actually different. White dogs produce the color white, whereas albino dogs appear white because of a lack of pigmentation.
Sometimes gene variants that give cats (and dogs) white fur can also cause deafness, though that doesn’t seem to be the case with w-salmiak. It’s one of many ways in which gene mutations that ...
