Age of a cocker spaniel with white hair on it's chin?

The presence of white hair on a cocker spaniel's chin can indicate that the dog is aging, as graying is common in older dogs. However, the exact age cannot be determined solely by the color of their fur. Cocker spaniels typically start showing signs of aging around 7-8 years old, but individual factors like genetics and health can influence this. Regular veterinary check-ups can provide more insights into a dog's age and health status.
