Older dogs, similar to this 10-year-old Neapolitan Mastiff, often grow grey hairs on their muzzles, and some dogs grow grey hair all over. Not all dogs gain grey hair when aging. Aging in dogs varies from breed to breed, and affects the dog's health and physical ability. As with humans, advanced years often bring changes in a dog's ability to ...
In this respect, if the aging process itself is addressed, then several age-related diseases could be delayed or avoided simultaneously. This is important because elderly individuals often have multiple chronic disease conditions. [4] The Dog Aging Project was founded in 2014 [1] [7] and received a US $200,000 seed grant from the University of ...

Senior dog food diets are pet foods that are catered toward the senior or mature pet population. The senior dog population consists of dogs that are over the age of seven for most dog breeds, [1] though in general large and giant breed dogs tend to reach this life stage earlier when compared to smaller breed dogs.
