Hi Sean,

It's possible your dog's nose is getting sunburned, wind burned or dried out from your heating system. You can try putting some Vaseline on it, which will help moisturize and protect it. But there is also a condition called discord lupus that describes what you are seeing as well.

Here are links to sites with more information on discoid lupus.

There are other causes of a loss of pigmentation that is discussed on the following site:

HiCustomer

Your vet can run tests to determine if it is discoid lupus which is the best way of determining if your dog has it. Vasoline on the nose should help stop sunburn from occuring where it won't help if it is discoid lupus. I have a smaller dog with mild discoid lupus. Just limiting his time outside in the sun seems to keep his nose problems under control.
