How to choose the Best Dog Food for Senior Dogs

As your dog ages, his digestive system, organs, muscles, and joints start losing the battle against time. Putting your best friend on a senior dog food diet is crucial to combatting these effects and ensuring he still enjoys a good quality of life in his winter years.

Senior dog food is specially engineered to contain all the vital nutrients needed to keep your aging dog mentally and physically strong. It’s also easier for your dog’s older stomach to digest, reducing the risk of constipation, or excessing flatulence or stooling.

The best senior dog foods have the following features as standard:

  • Vet Recommended – Top-quality senior dog foods have the approval of the veterinary community and are typically prescribed by vets. Before buying dog food for your senior dog, be sure to consult with your vet to verify the food has ingredients that will actually help your dog. It’s an effective way to avoid dog foods that may do more harm than good to the health of your aging dog.
  • High-quality protein content – Top-quality senior dog foods usually have a higher protein content. The high protein content keeps your aging dog’s muscles strong and aids the repair of deteriorating tissues. It also prevents kidney diseases. The protein source in the food is also important. Chicken is a common ingredient, but dog foods that use venison, lamb, and other lean protein sources offer better results.
  • Antioxidants, omega fatty acids, and glucosamine content – Antioxidants will keep your aging dog’s immune system functioning optimally. Glucosamine and EPA will support your dog’s aging joints, keeping him mobile and active.
  • Grain-free – A grain-free diet isn’t vital unless your senior dog has a grain or gluten allergy. Nonetheless, your aging dog’s body will benefit more from a diet that provides healthier carbs from low-fat foods like sweet potato, pumpkin, oatmeal, brown rice, quinoa, carrot, banana, and apple. These are easier to digest and won’t negatively impact your dog’s digestive or immune system.
  • Avoid artificial ingredients – Dog foods that contain artificial additives or preservatives, or animal by-products, should be avoided. Studies show that artificial foods can negatively impact your aging dog’s health, causing issues like allergies, tumors, digestive problems, kidney disease, and more.

Note that choosing the best dog food for your senior dog isn’t only about knowing the right features to look out for. You also need to identify your aging dog’s unique needs and know which dog food has the ingredients to meet those needs best.

What Things to Consider When Buying Senior Dog Food

To find a senior dog food with ingredients to best meet your aging dog’s needs, take the following factors about your dog into consideration:

Dog Breed

The senior dog food ingredients that work best for a small dog may not deliver the same quality of results to a large breed.

  • Small Breed Food: Small breed senior dogs need food that’s rich in protein, and that’ll help maintain their weight. If your small dog becomes overweight, it can cause a variety of health complications. Also, if it’s dry food, it should come in kibble size that’s small enough to fit into your small dog’s mouth and easily chew. If your dog has failing teeth, you might even consider soaking the kibble before feeding.
  • Large Breed Food: Large breed dogs age faster than smaller breed dogs. They also have shorter lifespans. As such, large breed dogs need foods that contain vitamins and supplements that’ll support their bones and joints, and possibly increase their longevity.

Nutritional Needs of Old Dogs

As dog’s age, they need food that they will have an easier time digesting. A high protein diet that uses real meat is helpful. Additionally, because older dogs are more prone to becoming overweight, their food must be nutrient-rich without increasing your dog’s chances of gaining too much weight.

It’s also important that the food contains less sodium and more fruits and vegetables. This will boost the cardiovascular health of your aging dog. Finding food with ample DHA, EPA, and glucosamine will support your dog’s aging joints, while antioxidants will keep his immune system strong.

To keep your dog’s skin healthy and fur shiny, Omega fatty acids must also be present in the food.

Health Conditions of Your Senior Dog

If your dog has any of the following conditions, he’ll require a special diet.

Joint Problems

Most senior dogs suffer from joint and hip issues, such as arthritis. To help with this, ensure your dog’s food contains glucosamine, calcium, phosphorus, chondroitin, or all four.

You can further assist your senior dog by adding ingredients like ginger, papaya, and alfalfa to their regular diet. These foods contain essential ingredients that’ll help minimize inflammation in your senior dog’s joints. While some of these, such as alfalfa, are common in dog food, you may have to look to treats to add in others.


Constipation is another common problem in elderly dogs as their stomachs become unable to properly handle food that they formerly could. You can minimize the likelihood of constipation by feeding your dog with a high protein diet that’s easy to digest and a high fiber diet that aids bowel movement. While looking for high fiber foods, though, avoid filler fiber. You want nutrient-rich sources from fruits and vegetables rather than grains.

Feeding your dog with senior dog food that contains prebiotics will also help.


If your elderly dog has diabetes, you can help him live a healthy, happy, and long life by feeding him food that contains high-quality proteins, complex carbohydrates, and fibers. This balanced diet must be supported by regular exercise to keep his glucose level under control.

Kidney Disease

If your senior dog is diagnosed with kidney disease, switching him to wet dog food that contains minimal sodium will help. More fruits and water, and less high-quality proteins will also help by reducing the workload on his kidneys.

Gum Disease

If your dog’s bad breath is worse, or his gums are bleeding, it could be a sign of gum disease. Dry dog food that’s rich in calcium and cleans your dog’s teeth as he chews can be helpful.


Is senior dog food necessary?

Dogs that are past their prime require fewer calories than younger dogs that are more active. Too many calories in your aging dog’s diet, and you could end up with an overweight dog, which only increases the risk of health problems.

Senior dog foods are designed to provide all the nutrients your dog needs, minus the excess they don’t need. For example, they contain more fiber to combat constipation, more glucosamine to combat joint issues, and more high-quality protein to support lean muscle mass.

While switching to a senior dog food may not be completely necessary, it is useful in keeping your older dog healthy and happy for more years to come.

When to switch to senior dog food?

Different dog breeds age differently. A smaller dog breed won’t be considered a senior until he turns seven. On the other hand, a larger dog breed is considered a senior by the time he turns five or six.

At these ages, an aging dog’s rate of metabolism will reduce. The immune system may also become less effective, making it the perfect time to switch your dog to senior dog food.

How much dog food to give to senior dogs?

The amount of food your senior dog needs will depend on his breed and size. Because your dog’s metabolism rate reduces as he ages, feeding him on the same schedule as before but with smaller portions is advisable. It will reduce his chances of becoming overweight.

For a more accurate recommendation of the right quantity of food for your aging dog, it’s best to consult your vet.

Can senior dog food cause diarrhea?

Senior dog food can only cause diarrhea if it contains ingredients your dog’s stomach doesn’t find agreeable. For example, the food may contain artificial ingredients or other ingredients that your dog is allergic to.

Diarrhea may also be caused by a sudden change in diet. It is why we advise slowly introducing your dog to senior food by mixing it a little at a time with his old food. This will give your dog’s stomach time to acclimate to the new diet.

If uncertain whether your dog’s diarrhea is caused by an ingredient in his new diet, consult your vet to verify.
