Why does my Coton de Tulier have a pink nose?

A Coton de Tulear may have a pink nose due to a lack of pigmentation, which is often influenced by genetics. Some dogs have naturally lighter or pinker noses, especially if they are not exposed to sun or if they have a specific genetic trait. Additionally, changes in nose color can occur due to health factors, such as seasonal changes or certain medical conditions. If you're concerned about the color change, it's best to consult with your veterinarian.
