The transition from adulthood to senior age in dogs and cats varies greatly and is partly subjective. For example, dogs differ in life expectancy and body size depending on their breed. However, regardless of the arbitrary moment when an animal is classified as “senior,” the biological changes associated with aging are evident, along with an increased occurrence and progression of various chronic diseases.
Cognitive Decline, Digestion, and Intestinal Bacterial Composition
Several physiological processes change with age, affecting overall quality of life. One of the most significant effects is cognitive decline, which can severely impact a dog’s emotional and social well-being, influencing daily interactions and overall life quality.
Moreover, aging affects digestion and the composition of intestinal bacterial populations. Over the years, the so-called “digestive fire” tends to weaken. This term, used in both traditional and modern contexts, refers to the energy and efficiency with which the digestive system transforms food into essential nutrients. The causes of this weakening include:
Impact on the Immune System and Metabolism
Aging significantly affects the immune system of dogs and cats, leading to a weaker immune response and an increase in chronic inflammation. At the same time, changes in energy metabolism occur: cells produce energy less efficiently, resulting in greater oxidative stress.
Mobility Issues
As animals age, many develop joint problems, such as osteoarthritis, which can limit mobility and negatively impact their quality of life.
Finally, a personalized nutritional plan, developed in collaboration with the veterinarian, is the cornerstone for addressing the specific needs of each senior animal in the best possible way.
A targeted nutritional approach is essential to counteract the physiological changes associated with aging and improve quality of life. A well-balanced diet, supplemented with specific nutrients, can help maintain overall health and an ideal body weight. Here are some key aspects:

Conclusions
Adopting a personalized nutritional and integrative management approach is essential for improving health, prolonging life, and promoting the well-being of dogs and cats as they age. The use of specific complementary feeds helps to compensate for nutritional deficiencies, improving quality of life.
For example, DogoSenior offers a balanced mix of natural ingredients designed to support mobility, brain function, and the immune system, thanks to the action of medicinal mushrooms Cordyceps sinensis and Ganoderma lucidum (Reishi), known for their energy-boosting, antioxidant, and immunomodulating properties.
Finally, a personalized nutritional plan, developed in collaboration with the veterinarian, is the cornerstone for addressing the specific needs of each senior animal in the best possible way.
