Predicting the coat colors of dogs is can be tricky, and genetics can be hard to understand so we've tried to break it down here for you! Dog Breeder Pro is a web-based software solution for dog breeders, with a range of useful features to help you keep track of pedigrees, waiting lists, test results and more. It also features a new advanced colour and coat genetics calculator that I've helped to design, so you can get detailed predictions for litters before you breed. There are several genes that contribute to your dog's outward appearance - but perhaps the most obvious are those related to your dog's coat color.
All dog coat colors start with two basic pigments, those for black (eumelanin) and red (pheomelanin). The coat colors we see are a modification of these pigmentation cells (called melanin). Learn all you need to know about coat color genetics in dogs with VCA.

Canine Coat Color and Type Background Mammals have two pigments that are the basis of hair color: eumelanin (black) and phaeomelanin (red or yellow). One of the genes involved in the production of these pigments in many species including dogs is Melanocortin 1 Receptor (MC1R) which is also known as the Extension locus.
Canine Color Charts A-Locus (Fawn, Sable, Black-and-Tan/Tricolor, Recessive Black) This chart explains what a dog's phenotype will be based on his genotype. This chart assumes the dog is "n/n" for the K. The Dog Color Genetics Calculator functions by using Mendelian inheritance principles across 21 loci to calculate potential coat color outcomes.
Each locus represents a specific gene that affects pigmentation, pattern, dilution, or modifiers in a dog's coat. Dog Color Genetics Summary: Genes & Alleles Overview This page is a quick reference to show you the possible alleles at each locus. Summary A list of variants and genes affecting coat colors and patterns in dogs: B locus The B locus determines if a dog has black or brown eumelanin.
B: Black Eumelanin b *: Brown Eumelanin. Dog coat genetics Dogs display wide variation in coat type, density, length, color, and composition Dogs have a wide range of coat colors, patterns, textures and lengths. [1] Dog coat qualities are governed by how genes are passed from dogs to their puppies and how those genes are expressed in each dog.
The genetic basis for these patterns is further complicated by breed-specific modifiers that can enhance or diminish certain traits. For instance, the Australian Shepherd's varied coat patterns, including merle and tri-color combinations, highlight the influence of multiple genetic factors working in concert.
