Hmm sorry if this double posts… my post disappeared after submitting
Senior foods really do not have anything special about them compared to adult foods. In fact, the label will usually state something along the lines of “complete and balanced for maintenance of adult dogs” even on senior foods.
Some differences in senior foods can include added glucosamine and chondroitin but you are already using a joint supplement anyway. Some lower the fat and calories because some dogs become less active as they age so may gain weight on higher fat/calorie foods. Some will also have lower phosphorus levels so the food is easier on their aging kidneys. None of Purina’s foods are particularly high in phosphorus though so you would not need to worry about an even lower amount unless your dog has current kidney issues. Some will also lower the sodium level for aging hearts, but again Purina’s foods typically are not that high anyway. If your dog had a heart or kidney issue due to old age that needed these nutrients lowered, you would be best off with a prescription food than a senior food. Because NONE of these things are actually a requirement to label a food as “Senior” so feeding a senior food would not even guarantee any of these benefits.
Most healthy seniors can stay on their original adult food for the rest of their life
The only supplements are personally use for my oldies are CBD oil for joint pain and CoQ10 for heart health. I do not bother with supplements much unless my dogs have a specific issue that needs to be addressed.
