Selecting the best senior dog food requires knowing what your individual pet needs. Though things like teeth, joint health and weight are often the first things that come to mind when thinking of food for a senior dog (and rightfully so!) thereโs something that often goes overlooked: Maintaining lean muscle mass. As with people, sarcopeniaโthe loss of muscle mass that accompanies agingโis also a concern for dogs. For healthy senior dogs who donโt have a medical reason for needing a low protein diet, protein intake is a priority.
Though dietary protein alone wonโt help any of us maintain all the muscle mass of youth, it is an important component. With protein in mind, Iโve rounded up my choices for the best senior dog food from some of the best dog food brands. Please discuss your petโs individual needs with your veterinarian before making any changes.
This is an absolute first step. One senior dogโs dietary needs may be significantly different than the next. Factors that need to be evaluated before selecting a food includeโbut are not limited toโlab results (such as kidney and liver function), body condition score, muscle condition score, dental health (can my dog comfortably chew dry food?), fiber content (does my dog need less fiber to increase the digestibility of their food?), sodium content (does my dog have a heart condition?), and fat content, to name a few.
Your veterinarian may also choose to formulate a diet specifically for your senior pet. They may partner with a nutrition service, such as Balance It (which is recommended for healthy pets by Cornell College of Veterinary Medicine), or they may refer you to a specialty veterinarian who is board certified in nutrition.
Look for foods where the protein is primarily from animals. Dr. Joseph J. Wakshlag, DVM, PhD, DACVN, DACVSMR, the Chief of Nutrition at Cornell Universityโs College of Veterinary Medicine says that for senior dogs, animal protein sources may be better than plant protein because animal protein has a better amino acid profile for dogs. Animal protein is also more digestible than higher fiber-containing plant proteins, which becomes important as a dog ages. In general, dietary fiber decreases a dogโs ability to digest and absorb certain amino acids.
Dietary fat is another factor when selecting a food. As dogs age, the propensity for body fat increases. Dogs who are overweight and/or have decreased activity levels may need to be switched to foods with reduced fat.
An upside of dry food is that dogs may accumulate tartar more slowly compared to wet food. A downside is that dogs with dental pain or not enough teeth to comfortably chew kibble, may gulp down unchewed kibble. Food is meant to be chewed.
Wet food is great for dogs who have dental issues, such as no teeth or just a few teeth left. Wet food also has significantly more moisture content, which can help with hydration. Whether or not a senior dog needs wet food, a combination of wet and dry, or dry food with or without added water, should be determined on a case by case basis.
Keep in mind that when evaluating the percent of protein, fat and fiber on a label for wet food, because of the moisture content, these โas fedโ values donโt directly correlate to the values on dry dog food labels. There are calculators online to help determine what the percentages translate to on a dry matter basis. โDry matter basisโ is the percentage of nutrients in a food when all moisture has been removed. But to complicate things further, dry food is not void of all moisture. It contains up to 14%. For fresh pet food products, some of them have both the โas fedโ values and the โdry matter basisโ values on their website but some do not. A simple way to compare wet food to dry is calories per cup, however that wonโt be enough information if your petโs protein, fat and/or fiber intake need to be between specific values due to medical reasons. Your veterinarian can serve as a resource in sifting through pet food labels.
Due to various biological factors as dogs age, their muscle mass decreases. Dr. Wakshlag says, โWe may not necessarily see it because the dog remains the same weightโ due to the amount of body fat increasing. He says that veterinarians often focus on Body Condition Score (BCS) but don't assess Muscle Condition Score (MCS.) Even though dietary protein alone isnโt enough to maintain lean muscle mass in an aging pet, it is an important component.
Since senior dog foods (which are labeled for dogs older than 7) vary widely in their nutritional compositionโparticularly in the area of proteinโthey may or may not be suitable for your pet. For example, Blue Buffalo Life Protection Formula Senior Chicken & Brown Rice has 18% crude protein (min.) whereas Blue Buffalo Wilderness Senior High Proteinโthat I featured in this articleโcontains 30% (min.) Breed also needs to be taken into consideration. A small breed dog isnโt a senior until 8 to 10 years of age but a large breed is a senior at age 7, and a giant breed at age 5.
For some dogsโbased on their physical exam, lab work, breed and physical activity levelsโan adult food (labeled for dogs between 1 and 7 years old), or an all life stages food (for dogs of any age), may be more appropriate. Your veterinarian, or a board certified veterinary nutrition specialist, is your best resource on which food best suits your petโs needs.
Nom Nom is a newer dog food company, founded in 2014, that offers four, gently cooked recipes for dogs. Their All Life Stages diets were formulated by board-certified veterinarians specialized in nutrition and are sold frozen, either as a subscription or through PetSmart. One of the reasons I like this food is because it doesnโt contain peas, chickpeas, lentils or dry beans. These ingredientsโalso known as pulsesโare being further researched, as theyโve been linked to some cases of canine diet-associated dilated cardiomyopathy (DCM), a type of heart disease. It also doesnโt contain potatoes or sweet potatoes, which are a lesser concern than pulses but are also being evaluated to see if they play a role.
This veterinarian-formulated food is one of the best wet dog foods, and it can be fed as a meal or used as a topper.
Not all of Blue Buffaloโs senior dog foods have enough protein for a generally healthy senior dog, but this one does. It also avoids the potentially problematic pulses (peas, lentils, chickpeas and dry beans), instead featuring ingredients like chicken, oatmeal and brown rice.
This senior diet has a nice combination of reduced fat, 30% protein, and nutrients to support skin, coat and joint health.
The interesting thing about a lot of senior dog foods is they tend to be low in fat (thatโs good) but also low in protein, e.g. 18 to 23% for dry food (not so good.) As I mentioned, I like a senior dog food thatโs higher in protein, preferably 30 to 32%, which is the recommendation from Dr. Wakshlag for a generally healthy senior dog.
Many โAll Life Stagesโ premium dry foods (e.g. Earthborn, Zignature, Solid Gold,) hit this ideal protein amount. But for a senior, the fat content in these is often on the high end of the spectrum (17 to 18%.) That is, except in this Wellness CORE โAll Life Stagesโ food, an adult (i.e. not senior) small breed food that is surprisingly what I want. This food also contains nutrients for gut, skin/coat and joint health.
With its moderate fat, high protein, and nutrients for joint and gut health, this adult maintenance diet for small doggos can be suitable for some healthy seniors.
Due to the low protein content of some senior dog foods, Dr. Wakshlag says that he doesnโt always recommend a senior diet. Blue Buffalo Wilderness Large Breed is an adult maintenance diet with a good amount of protein (28%,) low fat content (9 to 12%,) and joint support from glucosamine, chondroitin and omega-3 fatty acids. With your veterinarianโs guidance, they can help you determine if this is suitable for your healthy, large breed senior dog. However, depending on your large breed dogโs needs, the amount of joint support may not be enough. You should talk with your veterinarian about whether additional supplementation with a joint health product is needed.
If your large breed senior dog needs to be on a low-fat food, this chicken-based, adult maintenance diet with joint support might be suitable.
This easy to digest, All Life Stages, human-grade food is great for senior dogs with a sensitive stomach but who arenโt allergic to chicken. Itโs minimally processed and contains nutrient packed produce, such as carrots, spinach and cranberries.
If your senior dog doesnโt have a poultry allergy and your veterinarian has determined that peas and potatoes are okay for your pet, this food is one to consider.
This All Life Stages diet is low-calorie for the senior dog who might be less active or needs to lose weight. With an array of nutrients coming from ingredients like Alaskan pollock, carrots, blueberries and salmon oil, this food might appeal to the seafood loving dog.
This low-calorie, fiber-rich food is for All Life Stages and helps support skin, coat, gut and joint health.
This low-calorie, adult maintenance food has a nutritional profile which can be suitable for generally healthy senior dogs. It may also be a good pick if your aging pet requires a limited-ingredient dog food for allergies. But your veterinarian should ultimately determine if a diet like this is suitable.
This limited ingredient diet has the benefit of containing a single protein source, itโs chicken-free and pulse-free, and itโs lower in fat (crude fat minimum is 13%,) which is ideal for older dogs who are less active.
This low-fat diet contains nutrients such as glucosamine, chondroitin and long-chain omega-3 fatty acids (such as EPA) to support joint health. Itโs more ideal for less active senior dogs or seniors who are overweight. For dogs who are still fairly active, another alternativeโwith the same amount of EPA as Hillโs prescription j/d diet for joint healthโis Zignature Select Cuts Trout & Salmon. This was also my overall top pick for the Best Dog Food for Sensitive Stomach. This Zignature diet, however, contains 14.5% fat (min.), which is a bit much for an arthritic dog who needs to lose weight. Granted, EPA alone isnโt the reason to pick a food, itโs worth considering. Blue Buffalo True Solutions Jolly Joints is another overall good option but it has 15% fat.
If your senior dog doesnโt have a poultry allergy and your veterinarian has determined that peas are okay for your pet, this food is one to consider.
This meat-first senior food is budget-conscious while still containing prebiotic fiber for gut health along with nutrients from chicken, carrots, egg and marine microalgae. It only comes in one flavor but they do offer a large breed formula and a canned food option.
This budget-friendly, low-fat food meets the basic needs of generally healthy senior dogs, though itโs possible some dogs will need more protein, as determined by their veterinarian.
With its ethically sourced and human-grade ingredients, this โAll Life Stagesโ food (and brand) is the Rolls Royce of dog foods. Even though it has more than one type of fish, if your pet needs a poultry-free dog food for allergies, this food is one to consider discussing with your veterinarian.
This premium food contains nutrients that support skin and gut health, and is made by one of the best dog food brands.
Prescription dog foods (which you need vet authorization to purchase) address a specific health issue, such as joint health, brain health, gut health, etc. The prescription foods available in the United States specifically for joint health, which is a significant concern for senior dogs, are Purina Pro Planโs JM, Hillโs j/d and Royal Canin Advanced Mobility Support. (Eukanuba makes a veterinary diet called Joint Mobility thatโs available in Europe.)
There are also prescription formulations that address more than one medical issue, such as Blue Buffalo Weight Management + Mobility Support. Despite this food having salmon as the first ingredient, the primary reason I didnโt select it for senior dogs was because of its 17% fiber (max.) content. Fiber reduces a foodโs digestibility, which I discuss a little later.
All of these diets have pros and cons, so I picked Purina because it has 30% (min.) protein, whereas Hillโs j/d only has 17% and Royal Canin Advanced Mobility has 23%. The first two ingredients in j/d are wheat. In JM itโs brewers rice, but the second ingredient is trout. In the Royal Canin diet they are brewers rice and wheat.
The world of prescription food for joint health is limited but with 30% protein and nutrients to support joint health, this food can be a part of managing your senior dogโs arthritis.
I selected foods based on the overall quality of ingredients, favoring meat as the first ingredient instead of non-meat ingredients, by-products or meat meal/by-product meal. There are two exceptions on my list (Earthborn Holistic Venture and Purina ProPlan JM,) however veterinary nutrition specialists say that a quality food can still contain these types of ingredients. I also tried to pick foods with at least 28% protein, but several of them didnโt meet this amount. Finding the โperfectโ ready-made food can be a challenge, which is why your veterinarian may decide to partner with a veterinary nutrition service who can help you create, or find, the ideal diet.
With the exception of the prescription JM diet and the Iams diet, the products I selected arenโt formulated with corn, wheat or soy. I also picked foods that contain nutrients which support digestion and overall health, such as prebiotic fiber and omega fatty acids. Some even contain glucosamine +/- chondroitin for joint health, though Iโll admit, they may not be in sufficient quantities to make a clinical difference.
All of the foods I chose are complete and balanced, and are from reputable brands. The diets meet the nutritional guidelines of the Association for the American Feed Control Officials (AAFCO) for the life stage for which they are labeled, with the exception of senior dog foods. AAFCO doesnโt have specific nutrient recommendations for senior dogs, so senior dog foods meet the AAFCO requirements for adult maintenance. This is all the more reason to discuss your senior petโs nutritional needs with your veterinarian or a specialty veterinarian who is board certified in nutrition.
I also chose foods based on their protein content and fat content. For protein, I aimed for 28% to 32% and for fat, I aimed for under 15%, though some of the foods fall outside both of these ranges. How much dietary protein and fat your dog requires should be determined by your veterinarian.
Whether or not a food contained pulsesโpeas, lentils, chickpeas or dry beansโin the first three ingredients was a big factor in the foods I selected due to the FDAโs concern that, for some dogs, these ingredients may be linked with some cases of diet-associated DCM, a type of heart disease. Since more research is needed, I avoided exotic protein sources (e.g. kangaroo, buffalo, etc) for the same reason.
Yes, but not always in a good way. Many senior dog foods have reduced protein (e.g. 18 to 22% min. for dry food) but Dr. Wakshlag says that in many casesโfor dogs who are generally healthy and donโt have medical conditions where protein needs to be decreasedโdietary protein may actually need to be increased, such as to 28 - 32%. However, senior foods do tend to be reduced in fat, and that is generally a good thing.
Senior dog foods (and even some All Life Stages foods) will have a type of omega-3 fatty acid called eicosapentaenoic acid (EPA.) EPA reduces joint inflammation and can improve mobility in dogs. However, the amount of EPA in most non-prescription dog foods wonโt be enough to make a noticeable difference. This means additional supplementation under the guidance of a veterinarian may be needed. Dogs may need other types of joint health products as well, such as collagen and/or non-steroidal anti-inflammatory drugs (NSAIDs.)
An important factor for maintaining or building lean muscle is exercise, specifically concentric exercises (e.g. weight lifting in the form of carrying a weighted backpack.) Eccentric exercises, like walking and running, are also important but this type of activity doesn't do as much for building and maintaining muscle mass. But to avoid injuries or worse, talk with your veterinarian before implementing concentric exercises into your dogโs routine. Realize that for some dogs, concentric exercises just wonโt be feasible.
And two products worth discussing with your veterinarian that pertain to muscle health are Myos Canine Muscle Formula and CanEVA PETS.
Just because a food contains glucosamine, chondroitin, and/or omega-3 fatty acids, doesnโt necessarily mean the amounts are going to be sufficient for a dogโs joint health needs. In fact, itโs likely that the amounts in non-prescription dog foods arenโt going to be enough. Depending on what stage of arthritis your dog has, they may need additional joint health products. Your veterinarian can help you determine what those are.
Another interesting factor is that research is showing that though they are helpful for joint health, glucosamine and chondroitin donโt actually improve a dogโs mobility that much. So these two ingredients alone arenโt going to be sufficient for an arthritic dog with joint-related mobility issues.
That depends on your petโs breed. For small and medium breed dogs, they are a senior at 8 to 10 years of age. Large breed dogs are a senior at 7 years, and giant breeds at age 5. That being said, some dogsโ nutritional needs may be better met with an adult maintenance food or an all life stages food.
There is no one food that is the โhealthiestโ for all senior dogs. The nutritional needs of a 15 year old chihuahua with heart disease will be different from, say, a large breed senior dog who is generally healthy and active.
There is no one best food for a very old dog but factors to consider are the dogโs ability to chew food (do they need a smaller kibble size or wet food?), moisture content (would the additional water of wet food benefit this specific pet?), protein content (more or less?), fiber content (more or less?), sodium content (less?), fat content, and of course, palatability.
Keep in mind that dogs may turn their nose up at diets with less sodium and less fat. Letโs face it. In certain amounts, salt and fat can make food taste better! Ultimately, my personal take is that the quality of a dogโs life is more important than the quantity. That is, being miserable and hating your foodโbut living longerโis something to consider when assessing quality of life. And of course, this is a very personal decision.
Senior dogs donโt automatically need to be switched to wet food. Wet food is great for dogs who have dental issues, such as no teeth or just a few teeth left. Wet food also has significantly more moisture content, which can help with hydration. Whether or not a senior dog needs wet food, a combination of wet and dry, or dry food with or without water added, should be determined on a case by case basis. A downside of wet food is that dogs tend to accumulate tartar more quickly.
That depends on the dog. Some older dogs have medical issues that require them to be on a lower protein food. Other dogs may be generally healthy, and keeping them on a food thatโs around 28 to 32% protein is important to help them maintain as much muscle mass as they can. However, diet alone wonโt prevent the loss of muscle as a dog ages. Dr. Wakshlag says that even with a higher protein diet, older dogs will still lose muscle mass, partly because of their decreased ability to produce muscle. However, he says dogs on a higher protein diet may lose less muscle compared to dogs on lower protein diets.
