La longevity of a dog, which is of the order of 11 years and 3 months on average all breeds combined, varies according to its adult size (related to its breed): small dogs live between 15 and 16 years old, medium and large dogs 10 to 13 years old and some giant breed dogs such as mastiffs from 7 to 8 years old, although the latter become adults 12 to 15 months later than smaller breeds.

According to a recent study, puppies of large breeds have a very high rate of free radicals compared to small puppies. This would be due to a faster metabolism and growth increasing the amount of free radicals in the body of these puppies leading to irreversible damage to the cell participating in the shorter life expectancy of dogs of large breeds.

The longevity of a dog also depends on its heredity and its lifestyle. Its life expectancy improves if the animal receives daily a healthy and varied food (with vitamin and mineral supplements), sensory stimulation and emotional testimonies (hugs, games, visiting other congeners), practices physical activity ( long walks), has a bowl of clear water that is changed regularly and a quiet and comfortable place to rest.

The regular visit to the vet is also important. Sterilization and castration increases their life expectancy, because it prevents the development of certain diseases.

1 year The age for the dog corresponds approximately in humans to the age of a young adult (18 to 19 years on average, 16 years in the largest dogs and 20 years in the smallest). After 3 years, 1 year of dog is equivalent to 6 (dog under 15 kg) to 10 years (dog over 40 kg) of human age. Depending on the breed, a dog is considered to age between 7 and 10 years, although this depends on the individual (tarnished or graying coat, less energetic animal, weight loss or gain, difficulty in moving, etc.).

Over the past 15 years, dog life expectancy has increased by 25% in Western Europe.
