Guaranteed analysis: Rather than fixating on dog food ingredient lists, our experts say to examine the guaranteed analysis of important nutrients, including protein, fat, fiber, and other essential vitamins and minerals. Adult dog food must have a minimum of 18% protein and 5.5% fat to fulfill a dog's nutritional needs. As the AAFCO doesn't set specific standards for senior dog foods, the guaranteed analysis of these foods can vary significantly between recipes. Before selecting a food, our experts recommend asking your vet about the best food for your senior pup. To select foods for this guide, we spoke with two board-certified veterinary nutritionists and two small animal veterinarians. They helped us understand the unique dietary needs of senior dogs and what makes the best senior dog food. We've also had the chance to get input from our dogs by feeding them many different brands and types of food, some of which we included in this guide.

Wet dog food has a higher moisture content, typically 75% to 78%, whereas dry dog food contains only about 10% to 12% moisture. This is a perk for pups prone to dehydration or ones with reduced kidney function, which is common in older dogs, says Dr. Mark Freeman, a veterinarian and assistant professor of community practice at Virginia-Maryland College of Veterinary Medicine. These foods from Hill's, Wellness, and Blue Buffalo are formulated for senior dogs with sensitive stomachs.Contrary to what you may have heard, byproduct meats and meals help make pet foods more affordable, sustainable, and nutritious, Luisana says. That's why many budget foods will contain byproducts — typically organ meat, like liver, says Dr. Nancy Welborn, a veterinarian and associate professor of community practice at Louisiana State University School of Veterinary Medicine. "Meals are cooked meats or bones, ground up. They provide things like calcium, phosphorus, and protein," Welborn says, adding that pet food companies aren't permitted to include inappropriate animal parts in their products.

Healthy extras: The best senior dog food will contain extra ingredients that support their unique needs. For example, Freeman and Welborn highlight the potential benefits of antioxidants in supporting healthy aging. Welborn suggests a diet rich in antioxidants, such as Purina Bright Minds, if your dog experiences cognitive dysfunction. Other healthy extras for seniors include joint-healthy omega-3 fatty acids, glucosamine, and chondroitin. Freeman says some changes occur in older dogs' digestive tracts, such as reduced surface area for nutrient absorption. But generally, he says older dogs can digest foods and absorb their nutrients at nearly the same level as younger pups. Dr. Julie Churchill is a board-certified nutritionist, a Diplomate of the American College of Veterinary Internal Medicine-Nutrition, and a professor of nutrition at the University of Minnesota College of Veterinary Medicine. After completing veterinary training at Michigan State University, Churchill pursued Internal Medicine and Nutrition residencies and earned her Ph.D. from the University of Minnesota. Her interests include seeing patients in the clinic, mentoring students, and finding more effective ways to teach nutrition and facilitate the integration of nutrition into the care of all patients by healthcare teams.

Our experts say the following criteria are important to consider when shopping for senior dog food:

Calorie content: A dog's metabolism typically slows as they age, and many seniors are less active. So, senior dog foods usually contain fewer calories than adult formulations, according to Churchill. Freeman adds that overweight senior dogs are at greater risk of weight-related conditions like arthritis and diabetes. That said, feeding your dog less food could result in a nutritional deficiency. That's why Freeman recommends switching to a low-calorie senior diet or a weight-management diet based on guidance from your vet. Finding a food that your dog enjoys and knowing they will thrive on when they have a sensitive digestive system can be a challenge, but it isn’t impossible. Our wet food range has been formulated with the nutritional requirements of working dogs and dietary sensitivities in mind. No, our entire grain free wet dog food range can be fed to dogs as a topper to any of our dry foods or as a complete meal on its own. Does Skinner’s use mixed protiens in their recipes?Yes, the Skinner’s Field & Trial wet food range is grain free, as is the brand new Get Out & Go! range. is grain-free dog food just for dogs with sensitive stomachs? Feeding large breed dogs food specifically formulated for their size is crucial to reduce the risk of orthopedic issues. These problems can arise as early as puppyhood and become even more prevalent in their senior years. That's why Luisana recommends senior pup parents take a proactive approach and monitor dogs for early signs of joint and bone diseases. While some changes in behavior, like decreased activity, may be attributed to aging, Luisana says not to overlook the possibility of underlying orthopedic issues such as arthritis. Expert formulations: The dog food brands we recommend meet quality control standards. In other words, the brand employs a full-time board-certified veterinary nutritionist and potentially a PhD-level animal nutritionist, as recommended in the WSAVA guidelines. While you'll find wet food generally contains more fat per serving than dry food, it tends to have fewer calories per serving than kibble, and the water content can be more filling. When it comes to protein, the AAFCO recommends a minimum of 18% for adult dogs, but Luisana says senior dogs experiencing muscle loss may need more, and pups with renal or liver disease may need less.

Dr. Mark Freeman is a board-certified veterinarian and assistant professor of community practice at Virginia-Maryland College of Veterinary Medicine. Freeman earned his BS in Biology at Morehead State University and earned his DVM at Auburn University. His research interests include animal behavior and molecular biology. Instead of solely relying on the ingredient list to evaluate food quality, Luisana suggests considering other factors. For example, most quality brands will employ veterinary nutritional experts, provide ingredient tracing, maintain quality control measures, and contribute to research efforts. Senior dogs who have multiple tooth extractions or dental disease may also benefit from a soft food diet such as canned or fresh food, says Dr. Emily Luisana, a veterinary nutritionist at Friendship Hospital for Animals in Washington, DC.

Feeding-trial tested versus formulated foods: The best senior dog foods have been formulated — and in some cases, feeding-trial tested — to meet the AAFCO's nutritional standards for adult maintenance or all life stages. If your dog's food has an AAFCO label, you'll know the recipe fulfills the recommended protein, fat, and nutrient requirements for adult dogs. A label indicating feeding trials confirms the food's safety and palatability based on testing with a group of dogs. For this reason we've calculated the approximate 'as fed' percentages for the main ingredient categories in the finished product. Freeman says it's not unhealthy to transition older dogs to a senior diet based on their age alone. However, a more reliable indicator is overall healthier rather than age. Some dogs remain healthy throughout their senior years, so they may not need or benefit from a senior diet like other dogs might, he says. AAFCO nutritional adequacy statement for adult maintenance or all life stages: The AAFCO is a nonprofit organization that recommends nutritional profiles based on an animal's life stage. They don't approve pet foods or establish specific standards for senior dog foods. However, choosing a senior food formulated for adult maintenance or all life stages ensures the recipe fulfills the recommended protein, fat, and nutrient requirements of adult dogs. The best dog foods for senior pups will also contain beneficial extras such as glucosamine and chondroitin to support joint health and have fewer calories per serving than adult dog foods.
