This winter my dog's nose turned from black to a little pink, should I be worried A: There are several reasons a dog’s nose may turn a little pink. De-pigmentation or loss of pigment is usually harmless. It typically occurs in the winter and is called “snow nose”. We are not exactly sure, but experts believe it is due to the breakdown of tyrosinase – a temperature-sensitive enzyme responsible for producing melanin. Melanin is what is responsible for our skin, hair, and eye color. Some breeds are more prone to snow nose than others such as Bernese Mountain Dog, Golden Retriever, Labrador Retriever, Husky, and Shepherd.

Other things such as old age, allergies, injuries, and infection can cause changes in the color of the nose. If it is weather related, the nose will usually become darker in the summer. If you are unsure, call your veterinarian.
