My guess is it's normal, but I thought I'd ask you all...is it normal for a dog's nose to change color as it grows? Our pup is around 9 months and his nose started out black for the first few months we had him. I'm not sure when it started to changed, but somewhat recently his nose is turning brown up the middle (all along the crease up the middle). Normal or a sign of something going on?

Oh, I should add that he's a german shephard/australian shephard/other breeds mix.

its very normal for pigment to change right up untill about 2 yrs old.
if however it starts to look dry/cracked or 'odd" then have a vet check it

It's also normal for light coated, black or dark nosed dogs to have some pattern lightening such as you describe in colder weather.

Apparently their bodies are less efficient at manufacturing a particular pigment in colder weather, or maybe an enzyme in the metabolic process for that particular pigment doesn't work as well in colder temperatures, I can't remember, but at any rate you see it in the nose because it is always exposed to the weather and tends to be colder than normal body temperature in the winter. I am guessing that this is 100% normal.

Google "cold nose in dogs" or "snow nose in dogs".

Does he eat out of a plastic bowl? That can do it.

Never had a GSD with anything but a solid black nose for its entire life. But the aussies can have light noses.

Thanks all. He eats out of a metal bowl. He doesn't spend a lot of time outside since our yard isn't fenced in, so he's only in the cold when we go on walks or go outside briefly to go potty.

Our neighbors yellow lab has a black nose in Summer & a red nose in cold weather.
I thought they called that "rose nose" (???)
He eats out of a metal bowl . I thought I heard that metal bowls cause it.(???)

This yellow lab is 5-6 years old.

I've been trying to find a reference to seasonal nose color change in GSDs without success. I know that labs and goldens do it and that the exposure to cold that indoor dogs get (even in Texas) can be enough to trigger it, I also know that huskies and a few others do this as well.

Maybe that "other" the OP mentioned was lab.

Regardless of the standard, dark pigment is a major breed critieria for GSDs......could be why you don't see it so much. The founder of the breed and later ones associated lighter pigment with decreased scenting ability.

Then people argued it must be true because scent sensory cells arise from dermal cells, I believe.

But I do not believe there is any scientific support to that argument. For one thing others hold that a light pigmented dog is better in many bird dog breeds....

We aren't really sure what breeds he is, we got him from a shelter. He's a little over 45 pounds now. This pic was from Oct and his nose had already started changing colors then.
