I have attempted a color chart like
this before. It confused even me. I’m going to try again, listing
the main colors and modifiers. This chart is listed with only
genotypes. You may not necessarily know the genotype of your dog.
However, if the listed results match what you have in a litter of puppies,
hopefully this list will help you guess!

Conclusions:
Guessing your dog’s genotype is the one of the
oldest games in the book. A brindle can carry any number of other
colors. We know a brindle carries at least one red gene, but do they carry
both red and tri? Does he carry sable, or chinchilla, or one of the
dilutes? Look carefully at the chart. Sometimes certainly
color combinations give you a better chance at identifying your dog’s underlying
genetic makeup.
My stud dog is a bright red brindle. His
sire was a sable, his dam another red brindle. Looking back one more
generation (grandparents) didn’t help me much — they were all brindles.
Knowing that his sire is sable helps me with one clue — he couldn’t be
homozygous brindle because one parent is a solid color. In his first
breeding he was bred to a red and white bitch. It was the first breeding
for both dogs, so we waited to see if the puppies would give us any clues as to
the recessives each parent might carry. The first puppy born was a
tricolor. Eureka! We now know that the sire and dam both carry
tri. With the appearance of one puppy we knew the color genotype of both
parents. It usually isn’t that easy.
In Cardigan we have mostly dominant
modifiers. Dominants genes are easy — you must have a parent that color
to get a puppy that color (with the exception of sable, because brindle masks
sable). The recessives are more difficult because they can remain hidden
for countless generations. Chinchilla is that way, as well as both dilute
factors.
I hope this helps new breeders understand
Cardigan colors a little better.
