A dog's coat is composed of two layers: a top coat of stiff guard hairs that help repel water and shield from dirt, and an undercoat of soft down hairs, to serve as insulation. [1] Dogs with both under coat and top coat are said to have a double coat. Dogs with a single coat have a coat composed solely of guard hairs, with little or no downy ...
Dog fur is colored by two types of melanin: eumelanin (brownish-black) and phaeomelanin (reddish-yellow). A melanocyte can be signaled to produce either color of melanin. Dog coat colors are from patterns of: Eumelanin — black, chocolate brown, grey or taupe pigment;
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 types of colored patches generally appear in a merle coat: brown ...
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 Dog .
You could hide a whole new dog in there. One time, I had a very large foster dog with a very thick white coat. Like most fosters who come in off the street, there was no way of knowing her true breed.
When a dog has wild-type alleles at all three genes, it will have a yellow coat. When the dog has a loss-of-function allele at MC1R, it will have a yellow coat regardless of the genes it carries on the other two genes. Only a dominant black allele at CBD103 will produce a black coat color in dogs possessing wild-type alleles at MC1R and Agouti. [8]
