Every dog is an individual and all dogs are completely different to one another. They are all different shapes and sizes; some have long hair, short hair, sickle tails, curly tails, brown eyes, blue eyes, pricked ears, button ears, single coat, double coat and many more unique features.
Due to their individuality certain breeds of dogs can suffer with pigmentation on their nose. Sometimes this is completely normal and part of the ageing process, but other times it can be a medical concern that needs investigating further.
During the winter months certain breeds such as Siberian Huskies, Golden Retrievers and a few others are susceptible to a condition known as ‘winter nose’. Winter nose is where the dogs nose changes colour from Black to either Pink or White in the winter and then changes back to Black again in the summer. Other breeds that also have Black noses have had their noses turn Brown or Pink as part of the natural ageing process. A breakdown in the enzyme Tyrosinase is thought to be the root of the cause for both these conditions.
Injury could also be the cause of pigmentation in your dog’s nose, normally after a cut or scrape the nose may turn pink while it heals but then after the full healing process the dog’s nose should return to the normal colour again. Contact Dermatitis is also sometimes responsible for a colour change in your dog’s nose. Your dog may be sensitive to or allergic to contact with plastic bowls and this is why stainless steel bowls are normally recommended. Another cause of pigmentation could be Vitiligo which is an immune disease, certain dogs such as; German Shepherds, Dobermans and a few others have a higher chance with suffering from this disease. When antibodies are formed with Vitiligo they destroy the pigment cells and that is why pigmentation occurs.
Sun exposure, allergies, drug reactions or infections are all factors that can affect the pigment of your dog’s nose and cause it to change colour.
If your dog has a colour change in his nose but otherwise looks and acts healthy there is probably no cause for concern but if you notice ulcers, inflammation, or crusts this could be a sign of a more serious illness and needs urgent attention as if you notice any changes in your dogs appearance or in your dogs behaviour it is best to have him checked over by a vet because your dog may need some treatment.
