Thank you for your post! Is there an odor to the skin? When skin changes color like this, it can be due to a skin infection or allergies. Some breeds have darker skin and this can develop later in life. If you are concerned about this I would schedule an appointment with your veterinarian to ensure there is no infection present that needs to be treated. Please feel free to contact me with further questions / concerns.

    Thanks for using Petco Pet Education Center, formerly Petcoach! This may be due to an infection, inflammatory disease, immune mediated disease, among other possibilities. This would require at least some diagnostics such as cytology and perhaps a biopsy. I recommend that you have Bear evaluated by a veterinarian for further assessment and treatment. They would be able to check for these possibilities and treat accordingly. Good luck and have a good night!

    There can be various reasons that a dog's nose turns pink including age, infections, autoimmune diseases, idiopathic (no known cause), allergies, etc. It may just be a harmless change but you could have your vet examine your dog to determine if treatment is needed.

    What a cutie!! This mild amount of pigment loss is normal as a dog ages. I would not be concerned about it and there is nothing really that can be done about it. As long as your dog is acting like his normal happy, healthy self, you do not need to worry. If there are any crusts, lesions, or oozing present then this could indicate an infection or autoimmune disorder. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
