Dogs are often categorized as senior dogs by a combination of their breed and age, with small breeds considered "senior" at 10-11 years, medium-sized breeds at 8-10 years, and giant breeds at 5-6 years.

The appearance of gray on a dog's face and muzzle is often the first reminder a dog owner will be caring for a senior dog soon.
