To correct a previous post, I have been informed of Don’s color through a portrait of him. He was a liver dog, and he was within our modern definition of liver. However, he did carry the color for yellow, because of his Tweedmouth ancestry.
Keep in mind that yellow or reddish flat-coats were often registered as livers until the yellow color was opened for them in 1908. The in black and white photos of Don, he does appear to be a light liver dog or a dark gold one, but the revelation of this portrait, shows that he was a liver dog with dark eyes and lovely yellow shadings (which you would expect from a dog possessing yellow ancestors).
Let the record stand corrected.
