Urajiro

Urajiro is the name of a type of pattern that is most typically seen the japanese spitzes, but can also appear in other breeds all over the world, such as corgis, bulldogs and whippets. Urajiro is similar in placement to tan markings (though often covering more of the undersides). However, rather than being tan in colour, urajiro markings are pale white-cream. They appear to be able to appear on various patterns, such as sable, grizzle, brindle and tanpoint. They also appear to affect phaeomelanin but not eumelanin.
It is not known at this time how urajiro markings are inherited.

Could the same gene/s that give us uraijiro in dogs be responsible for the light markings seen in most wolves? This author suspects it is so, as the markings appear to be identic in placement and shade. Many breeds that come in grizzle, such as salukis, the jämthund and the shiba inu, express urajiro markings.
