Every animal is an individual causing nutritional requirements to vary extensively based on size, age, disease processes, etc. As dogs age, they tend to have decreased activity leading to decreased energy needs, gain fat, and lose muscle mass. Immune function and kidney function also decline with age although the degree to which this occurs depends on the individual animal.
It is important to do a careful nutritional assessment of the individual patient to determine an appropriate diet that will maintain proper body condition and provide optimal nutrient levels. If a dog has certain health conditions associated with aging, then dietary modification and supplements may be helpful, but if fed a high quality balanced diet, and the dog is in good body condition, then supplements are not really necessary.
The ones I recommend on a routine basis are more for joint mobility and decreasing inflammation in the body and include Glucosamine and Omega-3 Fatty acids.
