For years now, human medicine has moved from a disease based model to one of prevention and proactive care. Since about 70% of aging changes in our bodies are due to lifestyle and environmental factors, this approach has helped to increase our own longevity. Veterinarians are also making the shift and recommending more complete wellness programs for their patients in addition to multiple visits on an annual basis.

Most scientists believe that aging is due to damage in our cells caused by free radicals. The presences of molecules with an unpaired electron can create serious, cumulative damage in our cells leading to loss of function and ultimately, death.

Antioxidants are a popular answer to the free radical damage. These compounds, such as Vitamins A, C, and E or even melatonin or retinol, slow and prevent destructive changes to cells. Despite some proven benefits, antioxidants are still regarded with skepticism. Experts state that diet alone is not capable of providing enough antioxidants without serious consequences, such as obesity.

Maintaining a lean body weight, or caloric restriction, is another means to slow aging. Studies have shown in many species that reducing the intake of calories can lengthen life span.

Overall, pet owners should consider proactive disease prevention and prompt intervention to help their pet's live longer. These actions, combined with a good diet, exercise and regular veterinary visits are the cornerstones of your pet's good health.
