That is true,... a pug with this coloring is a sort of Siamese colored dog
i think ...it was was one of the cloring that was wanted the most after years of breeding and later accepted in the end for one of the accepted color pattern in the breeding book/kennel clubs...when i understand it right ^//^
i could be wrong, but are there not sighthounds with this color or a bit like this color too? and one of the large herd/stock protection dogs
and some horses.... and i think even one sheep breed that has the "siamese look"
would be interesting when one could find pictures
