The black muzzle is a sign of puppy in wolves - as far as I know the pups are removed from the pack hierarchy until around half year old, unlike in dogs.
Domestification actually causes preservation of some infant characteristics in adult dogs - like infantile behavior, big eyes, round head, smooth hair - some of them were even further supported by selection in pet breeds. It seems this was also true for black muzzle.

Ina, do you know what is the usual time for the muzzle to get light in carpathian wolves? It seems to me that most of wolfdogs have the light mask fully developed by 3 months of age, and i have seen some cca 2 months old pups with very distinct light masks in photographs...
