Nala's Winter Nose

Nala's nose is turning pink. So Kyle and I did a little reasearch and found out that she has winter nose! I took the first picture today and the picture on the bottom in October. You can really tell a difference in color.

Did you know.....

"The intensity of black pigment on yellow Labs is controlled by a separate gene independent of the fur coloring. Yellow Labs usually have black noses, which may gradually turn pink with age called "snow nose" or "winter nose". This is due to a reduction in the enzyme tyrosinase which indirectly controls the production of melanin, a dark coloring. Tyrosinase is temperature dependent—hence light coloration can be seasonal, due to cold weather—and is less produced with increasing age (two years old onwards). As a result, the nose color of most yellow Labs becomes a somewhat pink shade as they grow older."
