[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 ...
It is an inherited type of follicular dysplasia. It most commonly affects dogs with blue or fawn coats, which are dilutions of black and brown, respectively Dilution is caused by irregularities in melanin transfer and storage. Melanosomes may clump within melanocytes of the skin and hair follicles, causing the hair shafts to easily fracture. [5]
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 ...

Below, we compiled expert-recommended and NBC Select staff-favorite dog brushes, combs and deshedding tools for all coat types, including long-haired, short-haired and tangle-prone dogs.
The project took samples from 38 different breeds to find the gene (a beta defensin gene) responsible for dog coat color. 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 ...
