Clarification: Single and double coats are both acceptable as long as they are not hard, long, or woolly. Guard hairs (when present) may be a little longer. The coat on the left is short and soft. The coat on the right is long and harsh.
Clarifaction: Apricot-fawn may vary from cream to deep apricot or reddish gold. Silver-fawn has a definate clear silver cast and is seen rarely today, if at all regardless of the fawn shade, the important point is that the color be clear and distinctly contrasted with the black pigmentation of the mask, ears, and nails. A smattering of black-tipped guard hairs, hardly visible unless inspected closely, is quite common: this should not be confused with a smutty coat. Black coats should be very glossy with no rust or grey.
Undesirable: Fawn, smuttiness: indistinctive colors; a 'bleeding' of the black areas into the fawn; broad saddles; white spots. Black: grey or rusty cast; white spots. Pugs should be judged with no preference for either fawn or black coat color. If the silhouettes are correct, the black Pug's outline is an advantage over the fawn's. If the silhouettes are equally faulty, the black will appear faulty to a greater degree. The black color also gives the optical illusion of finer bone, less substance, and smaller size. For this reason the judge must give particular attention to the black's head and substance to ascertain that all necessary quality are present and are not overlooked. A few white hairs found on the chest of either fawn or black are permissible on an otherwise excellent speciman. As both colors age they may develop frosting on the muzzle. This should not be penalized.
