white hair on dog's snout
my GSD just turn 4 about 2 months ago, I have notice that since about 3 yrs and on he has white hair around his snout. now he had his share of skin problem (allegy and the recent weird wart on his lip) btu otherwise he is quite healthy and still have the energy of a teenager. Is white hair on the snout a sure side of age or other health related problems? my gsd is mainly black dog and his snout is compeletly black, could white hair appear earlier on dog with black snout?
