Did you know that aging in dogs covers the impact of aging in the domestic dog, common medical and clinical issues arising, and life expectancy. Older dogs, like this 10-year-old Neapolitan Mastiff, often grow grey hairs on their muzzles; some dogs go grey all over.
As with humans, advanced years often bring changes in a dog's ability to hear, see and move about easily. Skin condition, appetite and energy levels often degrade with geriatric age, and medical conditions such as cancer, renal failure, arthritis and joint conditions, and other signs of old age may appear.
