So What is the Best Senior Dog Food?

As with anything, the best food for your senior dog is going to vary based off of quite a few factors.

Your dog’s age, breed, health, and activity levels are just a few of the variables we can name.

Making it pretty confusing and difficult to determine precisely when to make the switch from adult to senior dog food.

For example, smaller breeds tend to mature faster. And once they reach adulthood, start to age slower.

Larger breeds could be considered senior citizens at around age 5 or 6. That said, most vets consider dogs to be part of the elderly once they become 7 or 8 years old.

With age comes an assortment of health issues. Requiring veterinary care and maintenance, making the best dog food for senior dogs a prescription diet in some cases.

Signs of Aging to Keep an Eye Out For

If your dog is showing any of the following signs, it may be time to switch them to senior dog food. The hints of aging in dogs to look out for include:

  • Lack of energy, sensitivity or intolerance to exercise, or a limit in mobility.
  • Sudden loss of appetite or weight loss/gain.
  • Gray, thinning, or drier fur and coat.
  • No restraint or other bathroom issues.
  • Getting tired quickly or sleeping more than usual.
  • Getting lost or confused – this could be a sign of Canine Cognitive Dysfunction Syndrome or Alzheimer’s.
  • Behavioral changes – such as increased whining, or apprehension and fear of loud noises.
  • Lack of response to commands – may be a symptom of Alzheimer’s or an indication of hearing problems.

Health Issues That Come With Age

As with humans, when dog’s age – their health and stamina slowly decline. The body’s ability to maintain normal functions and repair itself deteriorates.

Their metabolism starts to slow down, and they struggle to adapt to the stresses and changes in their environment.

Senior dogs also can experience a few health problems as well. Such as:

  • Joint Problems – like hip dysplasia or arthritis.
  • Diabetes
  • Kidney Failure
  • Liver Disease
  • Heart Disease
  • Constipation
  • Weight Gain or Loss

The more common of them being joint problems and constipation. It’s highly important to ensure your senior dog’s food caters to these health issues.

However, as previously mentioned, for the more serious ones – a veterinary prescribed, specialized diet may be required.

Nutritional Adjustments for Senior Dogs

A few of the nutritional adjustments that will be required once your dog joins the rankings of senior citizenship are laid out below.

Higher Protein Content

Just like with humans, senior dogs start losing muscle mass as they age. As a result, the protein stores of older dogs get depleted more quickly than in younger dogs.

To make up for that muscle loss and replenish their protein supplies – senior dogs require foods that have high protein content.

That said, it is recommended that per 1000 calories, there should be at least 75 grams of protein in an older dog’s diet.

However, if your senior dog has kidney disease, this could be detrimental and worsen the illness. As in most adult dog food, the phosphorous content increases parallel to the protein.

Something you want to avoid with kidney disease is the increase of the phosphorous content.

Therefore, you should consult with your vet on how to reduce phosphorous intake while still being able to increase the needed protein.

More or Less Fiber

Psyllium is a fiber blend of both soluble and insoluble fibers that is commonly used in senior dog foods. Which is great for improving the general health of your dog’s gastrointestinal system.

Too much fiber can compromise the ability to absorb other essential nutrients.

Whereas a diet rich in fiber, but not too much, will help relieve your older dog from constipation.

Calorie Density

As with any dog, there is no one-size-fits-all answer when it comes to the calorie intake for senior dogs. It depends on whether your senior needs to lose or gain weight.

Most vets and experts recommend low-calorie diets of around 350-450 calories per cup of kibble. Since senior dogs are not as active as they were when they were young.

Digestibility Ease

Older dogs are more vulnerable to digestion-related problems as they age. Such as food allergies, inflammatory bowel disease, and pancreatitis.

Senior dog foods that use high-quality, naturally sourced ingredients that are hypoallergenic are a good preventative measure. Especially if they are easier for their digestive system to break down.

Joint Supplement Additions

Older dogs, especially if obese, are more susceptible to arthritis and other joint issues. You should supplement their diet with glucosamine and/or chondroitin to reduce these symptoms.

Also, consider foods that have nutrients proven to minimize inflammation in the joints. Such as omega-3 fatty acid rich EPA and DHA.


The great thing about all of these products is they don’t need a veterinary prescription to purchase them.

And quite a few do target special needs of senior dogs – like joint problems and digestibility.

Senior dogs need a well-balanced dog food that’s high in fiber, low in calories, and contain sufficient amounts of fat and protein.

There were two that it was tough to decide on a winner between, but alas, there can only be one victor in the end.

With Hill’s Science Diet Adult 7+ Small Bites Chicken Meal, Barley & Brown Rice Recipe Dry Dog Food as a close runner up.

The best dog food for senior dogs in our opinion and the winner out of all the products we reviewed is Nutro Wholesome Essentials Senior Farm Raised Chicken, Brown Rice & Sweet Potato Recipe Dry Dog Food.

They source a lot of high-quality, natural ingredients and not a lot of fillers or additives.
