Foods that are formulated for specific life stages are designed to provide optimal nutrition for a pet during a specific age-range or life event. The most obvious example of foods like this are those formulated for puppies, and it makes sense that puppies would likely have different nutritional requirements than other dogs, since they are growing rapidly. The specific nutritional needs of senior dogs are a bit less clear-cut, however a diet that is slightly restricted in calories is likely of benefit to them, as many of them aren’t as active as younger dogs. Many can also benefit from the addition of ingredients such as omega-3 fatty acids, as well as supplements that may improve joint health, such as glucosamine, chondroitin, and MSM. In general, senior diets are a good choice for most older dogs.
