Hi! I have a 1 year 10 month old yellow American lab. He has cream colored whiskers. Just in the last week or so we have noticed just one whisker has a black outgrowth of about 1/4 inch, the rest of that whisker is still pale cream colored. Does anyone know what this means? Is it an aging thing where then all his whiskers will eventually change color? Or is it a sign of something medical? Thank you in advance for insights!
