Dog Color Feature: White Spotting Modifiers

This is a supplement to my Theoretical Dog Genetics guide Theoretical Dog GeneticsAs a kid I remember being confused by the logic of dog genetics presented in cartoons. When two dogs had puppies, the boys looked like the dad and the girls looked like the mom. I can only guess that this lack of originality was an attempt to cash in on the new character's resemblance to an older character that had already won people over, but where's the fun in that? Being the animal nerd that I am, I wanted a realistic guide to prevent such blandness.
How to use
Much of this has not yet been proven in studies with real dogs, so if you want to learn more about a real dog it is useful to research the specific breed or likely breeds that are in the dog's background.
Each locus is a spot which can hold two possible alleles out of any number present in the whole species. All together the alleles (genotype) give the final appearance (phenotype). To decide the appearance of offspring, give each parent a full list of genes to describe their appearance and "breed" them by randomly sele. I am using thumbnails from dA so that artists will get the credit that would be harder to give taking pictures from other online sources. The goal is to educate anyone who is curious, as well as to provide artists with references that will improve the realism of their work.
I am still learning, and guessing the correct color can sometimes be difficult even with an ideal photo or the dog itself to examine. If you spot any mistakes let me know.
If you see your picture here and don't want it to be let me know and I'll take it down.
If you would like to contribute a picture for reference send me a link. Photographs need to be clear, in good lighting, and show enough of the dog to provide a good reference for markings.
I will be going back and adding to this whenever I find new references. My personal goal is to improve the quality of my art and educate myself because I like to know more about the patients I meet at the vet clinic where I work as an RVT.

Modifiers of White Spotting- Since white spotting covers all other patterns, any gene that lets color show through on a white area will reveal those colors as they would be seen on a solid colored dog.

Ticking: Small spots of color show through in white areas, especially on the legs and muzzle. Two copies of the gene could be responsible for heavier ticking patterns. Dominant.
    Australian Cattle Dog/Border Collie mix Australian Shepherd Beagle Bretagne Spaniel Bukovina Shepherd Dog Cattle Dog mix  Clumber Spaniel English Setters English Springer Spaniels Mixed breed
Dalmatian spots- A modifier of ticking that makes the spots larger and more evenly distributed. Larger patches of solid color are piebald markings.

Roaning: Heavy sprinkling of colored hairs in white areas. More dense and evenly distributed than ticking. Dominant.

Split Face: Causes half of the face in Irish or Piebald patterns to be white. Markings are not always symmetrical, but this amount of extra white could have a genetic basis.
Border Collie  Cardigan Welsh Corgi Whippet

Lozenge: A large spot of color appearing on the head, neck, or chest in a dog with white markings covering the area.
    Alaskan Husky Australian Cattle Dog  Beagle Great Dane mix Mixed breed  Siberian Huskies

White Spotting Pools: This may be a modifier of agouti locus patterns or caused by the heaviest expression of the mask gene ("chest shading" in solid dogs). The legs/chest show darker red than the rest of the body, as if the pigment is pooling and intensifying on the lowest areas bordered by white.
Saint Bernard

Scarring: White hair growing back after an injury, similar to freeze branding in livestock.

Age-related Graying:

Interesting Variations: Could be genetic, or just one of the cool random things that makes each animal unique.
