Tibidou's nose in summer:

Tibidou's nose in winter:

Same here – we’ve noticed a bit of depigmentation on the left side of our Ridgeback's nose during the cold spells.
The vet put him on a course of antibiotics for a week, just in case it’s an ulcer caused by some kind of fungus.
We cleaned it with Betadine for about a week too.
It’s looking a bit less pale now, but then again, it’s not been quite as cold lately, so I couldn't really say for sure.
Either way, it looks very much like "snow nose"...
Tibidou is one of those pooches with a 'snow nose'—pink in the winter and black in the summer. He’s definitely got some Yorkie in him!
Hi there,
You're right, this change in colour can indeed be seasonal: a dog's nose often lightens in the winter and regains its pigment in the summer.
However, it would be best to see your vet for a specialist dermatology consultation. Depending on the cause of the pigment loss, the vet can then decide on the most appropriate treatment.
Also, bear in mind that most types of nose discolouration make the skin much more sensitive to the sun. During the summer, you'll need to make sure you protect it to avoid sunburn by applying sunscreen—ideally a gel, as it absorbs more quickly and is harder for them to lick off.
Best wishes,
Manon
It could be what’s known as "snow nose" – this loss of pigment often happens in winter, which is where it gets its name.
As long as there are no signs of infection, itching, or discharge, I’d suggest waiting a few months. If the colour hasn’t returned by the summer, you'll need to take them to the vet to get it checked out.
