Answer
Hi Gill-

Schnauzers tend to have slight color changes as they grow, and the change in the climate is most likely a bit responsible as well. I would not think that it is due to diet. However, without seeing the dog I would not be able to really diagnose, so I would suggest if you are concerned to take him to the vet. Thanks!
