In our opinion, it is normal for Labradors to have black noses, but many owners will find that this is not the case. Many times the noses of Labrador retrievers are not black. , this phenomenon is related to many factors. Some labradors may have black ears when they are young, but as they age, the color of their nose also changes, which is mainly related to their own genes, so it is difficult to change, but for some We can still improve the discoloration of the nose.

Labrador red nose is related to temperature and genes

In our opinion, it is normal for a Labrador to have a black nose, but many owners will find that this is not the case. In many cases, the nose of a Labrador is not black. This phenomenon is related to many factors. . Some labradors may have black ears when they are young, but as they age, the color of their nose also changes, which is mainly related to their own genes, so it is difficult to change, but for some We can still improve the discoloration of the nose.

The reason why some Labrador Retrievers do not fade away is related to their own genes, while others are related to the external environment. We know that dogs in winter, Discoloration of the nose occurs. This is because it is related to the enzyme responsible for the production of melanin on the nose of the yellow Labrador dog. It is just the opposite of tyrosinase. It is not stable at low temperature, so in the low temperature in winter, this enzyme will stop producing. chemical reaction. The rate of conversion to eumelanin on the skin will slow down, and the melanin on the nose will slowly fade away. In addition to this, certain drugs or toxic substances are also one of the reasons for the pigmentation to fade.

Melanin is a black substance that produces color in the skin, eyes, and hair of humans and animals. Sufficient to protect humans and animals from intense sunlight exposure, two pigments have been found in Labrador retrievers

Eumelanin is the pigment responsible for producing black and Phaeomelanin is responsible for producing red/yellow. It is important to note that Phaeomelanin is only found in cells that make up coat color, not in cells that make up skin.

Generally, the nose of a Labrador is black or dark brown. If a Labrador's nose is pink, it means there is no pigment. It is called Dudley's nose. This situation will be deducted during competition. Yes, but that doesn't mean the dog isn't a Labrador, it's just a lack of pigment.

Sun exposure improves dog nose fading

About Dudley: Dudley is a yellow labrador with a recessive chocolate chromosome More, it can also refer to the nose or the eye frame, which is a pink, labrador without any pigment, but it's actually not very common. Perhaps the cause of this phenomenon is a genetic mutation, of course only possible. It's important to understand, though, that even though having such a trait isn't an ideal situation, it doesn't mean it's a genetic mutation. There is currently no evidence that Dudley noses are associated with poor health.

In fact, not only will Labrador retrievers die, but many dog breeds will have pink noses, such as: Samoyed, Alaska sled dogs, Husky, etc., this is also due to the change in temperature, which leads to the occurrence of pink noses. Many yellow lara have black noses in summer, and their nose color will fade in winter, and it is cyclical, which occurs almost every year.

This kind of pink nose is also called Winter nose or Snow nose. To distinguish the pink nose formed by fading of the nose, what is the difference between the pink nose and the other kind called Dudley If so, just check your dog's eye sockets and mouth. Normal dogs have melanin in these areas, while Dudley's dogs are pink or tan.

Therefore, the reason for the fading of the Labrador's nose is caused by the weather, in addition to its own genes, so in general, the owner does not need to worry, usually pay attention to nutritional supplements and sun exposure can get a certain amount. improvement.
