My Goldens have always had brown-pink noses. Roxy is the only 1 of the yorkies with a brownish-pink nose. I just say they were there hearts on their faces! They have dark black pigments around their eyes and mouths though.
I tried kelp with golden # 2, Laney. It did not work. It is genetic... I have friends who say that if the golden has a black roof of the mouth then it will have good pigment. And some golden noses fade in winter, but darken in the warmer months..snow nose.
