If a pug dog has a white patch on its chest does this mean it is not a purebred?

QUESTION: If a pug dog has a white patch on its chest does this mean it is not a purebred? I have heard that there are no white pugs so where would the white on one come from if not crossed somewhere.

ANSWER: No it can be purebred. A white spot on the chest is a sign of incomplete pigmentation. It is common in nearly all breeds. This is from the breed standard:’DisqualificationsWry mouth teeth or tongue showing. White anywhere but the chest. The white on the chest not to be larger than a dime.’’disqualifications’ means they can’t show in conformation but can in agility or obedience and can be registered.
