When two different looking dogs had puppies, the boy puppies looked like the dad and the girl puppies 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 resolved to give myself a way to design 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 you the final appearance (phenotype). To decide the appearance of offspring of two characters, g

Here I tried to create something that looked like an Akita that came in chocolate, but the program I use to randomly select genes didn’t quite cooperate.
