I would not call him a saddleback but probably black with brindle trim or black brindle.
There is a big controversy going on now within the plott breed over solid colors. either bucksins or solid black are not acceptable colors in UKC. I myself think if you have either to registered ukc parents they are just as pure as the brindle ones. Never breed for color but ability.jmo
Great point Cajun, form always need to follow function imo. Once people start breeding for color or looks it is the first step in the wrong direction imho. I have never seen a maltese, could any of you post some pics of some?
