My dog's nose lost pigmentation suddenly. Is it serious? Vet visit?

Thanks for using Petco Pet Education Center, formerly Petcoach! Dogs can have changes in the pigmentation of their nose. This is rarely due to any significant medical reason. I do not think that you need to worry about this thankfully. Good luck and have a wonderful day and new year!

Thanks for using Petco Pet Education Center, formerly Petcoach! This is probably from him rubbing his nose against a cage or something like that. I would suggest checking on that possibility. Otherwise, if that is not possible and this continues have him evaluated by a veterinarian for further assessment and treatment to check on a possible infection. Best of luck!

Thanks for using Petco Pet Education Center, formerly Petcoach! The little area of discoloration is not necessarily anything to worry about. I see this commonly with time with dark skinned animals. As long as the skin does not seem irritated and the discoloration does not happen on the nose itself, I am inclined to just continue to watch it. Apply a dab of children’s sunscreen lotion before she goes outside to protect that area from sunburn. Best wishes to you and Luna!

There are a number of reasons for loss of pigmentation on a dog's nose, most of them just cosmetic, which is what yours appears to be. As long as the skin remains healthy and normally textured, I would just to bring it up to your vet the next time your dog is in for his annual visit or take a picture and send it to them now to see what they have to say about it.

It is hard to say what it is without seeing and examining your dog. It may be just de-pigmentation of the nose, potentially it could be a form of superficial infection. As long as your dog is not bothered by the change, is bright, is eating and drinking as normal it should be safe to wait until your vets re-open for consultations.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This could even be the site of an infection. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good night!

There are breeds of dogs that are prone to a seasonal lightening of the nasal planum (the hard, tough, hairless end of their nose). Sometimes referred to as “Snow Nose” these dogs (Siberian Huskies, Labradors and Golden Retrievers) can have darker noses in the summer months and lighter noses in the winter. These same breeds plus German Shepherds, Samoyeds, Afghan Hounds and Dobermans (among others) can also experience a gradual or waxing and lightening or fading of their nose color over time. This condition is known as “Dudley Nose." Vitiligo is a progressive disease in which the melanocytes are gradually destroyed causing unpigmented areas on the skin. They develop pigment loss from their skin or hair on their heads, but it can occur in other locations too. In some cases, antibodies against melanocytes have been identified in the serum of infected dogs indicating an immune component to the disorder. And skin biopsies of the affected areas will typically reveal a total lack of any remaining melanocytes. What all three of these causes for depigmentation have is common is the fact that they are not a disease that can bother or hurt your dog at all. There is no reason to worry about them and there is nothing to be done to ‘correct’ them. The depigmentation is purely cosmetic. Some depigmentation is cause for concern. For instance, any contact dermatitis/irritation can cause depigmentation as can certain chemicals in rubber that can affect the production of melanin pigment where the rubber touches the skin. The administration of certain drugs like ketoconazole, procainamide, and vitamin E have been reported to cause generalized changes in coat color in dogs, and injections of other drugs (glucocorticoids, for instance) can cause localized loss of pigment. Additionally, hormonal disorders (imbalances of thyroid, adrenal or sex hormones) can alter pigmentation as can bacterial and fungal infections and even cancers (neoplasias). Immune-mediated diseases also occur in dogs where the dog’s own antibodies attack different parts of the skin resulting in depigmentation. I recommend getting your dog seen by your vet just to be safe. She is young for some of these conditions to occur, but nothing is impossible.
