Purina ONE® Senior Dog Food

Dogs’ nutritional needs start to change when they reach age 7. That’s why Purina ONE Smartblend® Vibrant Maturity® Adult 7+ Formula dry dog food uses enhanced botanical oils and high-quality carbohydrate sources like oat meal and whole grain wheat. These help promote mental sharpness and healthy energy in senior dogs. You may even see an average increase in activity level over 20% when you feed it to your older dog! Plus, this easily digestible dog food is made with real chicken as the #1 ingredient to help keep him coming back meal after meal.


"I took the 28-Day Challenge when I switched Wacha to Purina ONE years ago, and absolutely saw a difference in his energy and coat. Now that he’s 7, we’re making the 7-Year Switch to Purina ONE Smartblend Vibrant Maturity Adult 7+ Formula."
