When To Switch To Senior Dog Food? (Vet Answer)

In contrast to puppy food and adult food, "senior dog food" is not strictly a food category. As with pups and adults, the AAFCO does not establish particular dietary guidelines for senior dogs. Still, you've likely seen senior dog food on the shelves of your local pet store. So, what is this all about?

Dogs are prone to acquire a number of health issues as they age. For instance, many senior dogs have joint difficulties (just like older people). A variety of extra components in senior dog diets may help delay the advancement of these conditions.

The majority of these senior dog diets are otherwise identical to adult dog foods. While elderly dogs tend to be less active, some have a lower calorie content. Yet, this will vary.

Certain dogs may benefit most from senior dog food when they begin to exhibit indications of age, according to this information.

Whether your dog has difficulties with his eyes, joints, or skin, senior dog food may be able to assist. There are other aspects to consider, such as your dog's current food. Hence, there is seldom a universal age at which your dog must transition.

To assist you choose when to start feeding your dog senior dog chow, let's examine all the relevant criteria in "When to Switch to Senior Dog Food? (%year% Vet Answer)" by BestForPets (bestforpets.org).

Factors to Consider When Switching to Senior Dog Food

Here are some of the most critical considerations to make when transitioning your dog to senior food. As you will observe, age is not among them.

  • Health Conditions: 

Changing to senior dog food may be necessary if your dog develops age-related health concerns. For instance, senior dog meals typically address hip and renal issues.

When in doubt, speak to your vet. Certain canines may benefit from a veterinarian diet as opposed to an elderly diet.

  • Weight Gain: 

Elderly dogs may not be as active as they previously were, leading to weight gain. If your senior dog begins to gain weight, you may choose to select a senior dog food with less calories. Instead, a weight-control adult meal may also be acceptable.

  • Weight Loss: 

Some senior dogs lose weight as opposed to gaining it. If this occurs, consult a veterinarian to rule out any underlying health issues. If your dog does not have an underlying health condition, you may choose to increase their caloric intake.

Consult with your veterinarian to pick a senior meal with additional calories. Do not assume that a senior dog food has more calories merely because it is advertised for older dogs; calorie content varies greatly across senior dog meals.

  • Current Diet:

High-quality adult dog diets typically contain the same ingredients “added” to many senior dog foods. Glucosamine, a typical joint supplement, may be found in a variety of high-quality human diets and senior dog foods.

If your dog is currently consuming one of these high-quality diets, it is usually unnecessary to modify their food.

Common Misconceptions About Senior Dog Food

There are some widespread myths regarding senior dog food. So that you don’t mistakenly transfer your dog to senior food, let’s examine a few of them.

  • At age 7, all dogs must convert to senior food.

There is no certain age at which a dog should move to senior food. Some dogs may never require senior dog food, while others may require it as early as age five. Thus, you need rely on other signs besides age.

  • All meals for senior dogs are same.

There is no statutory definition of the term “senior diet.” While some diets for seniors are low in calories, others are far more. Hence, while selecting a product, always examine the nutritional label, since they might differ considerably.

  • Older dogs require lesser protein.

There is no evidence that older dogs require less protein. In fact, a low-protein diet can be detrimental to the health of many elderly animals, as it may accelerate muscle wasting.

Some senior dog meals have more protein, while others contain lower protein. It is unknown if increased protein intake at this age is beneficial, but we do know that decreasing protein intake is not optimum.

  • Senior dog meals have a reduced phosphorus content.

Phosphorus has been associated with canine renal disease. Thus, many individuals believe that all senior dog chow is low in phosphorus.

Yet this is not the case. Many do not regulate the phosphorus content of their dog food. Due to this, a veterinarian diet is frequently the best option for dogs with severe renal issues.

  • Senior dog meals have a reduced salt content.

As many older individuals require low-sodium diets, many people also think that senior dog chow is low in salt.

Nevertheless, salt levels in senior dog food vary greatly, and not all senior dogs require sodium levels that are managed. In general, sodium restriction is not recommended for older dogs.

  • Senior canines require more fiber.

An excessive intake of fiber is not necessarily advised for elderly animals. In some instances, a high-fiber diet may be suitable, such as for overweight senior dogs. Conversely, a high fiber content might cause underweight dogs to eat too little, resulting in accelerated weight loss.

  • All seniors require nutritional supplements.

In most circumstances, if your dog is consuming a healthy diet, they do not require a supplement. Some illnesses may necessitate supplementation, but the normal senior dog certainly does not require additional vitamins or minerals.

Consult your veterinarian before administering any supplements to your dog, since they are all susceptible to adverse reactions.

Is Senior Dog Food Necessary?

No. Senior dog food is not necessary for the vast majority of dogs. While certain older dogs may benefit from particularly specific senior dog food formulations, the ordinary senior dog may continue to consume high-quality adult food.

Elderly animals in good health and physical condition typically do not require a change in diet.

Yet, dogs with age-related problems may choose to adjust their diet. In senior diets, renal disease, arthritis, and diabetes are frequently addressed.

Yet, these diets differ significantly. Hence, you must collaborate with your veterinarian to identify the optimal food for your senior pet. Do not assume all senior dog diets meet the criteria.


There are several excellent senior dog meals available. The AAFCO does not regulate this category, therefore anything can be labeled senior dog food.

Recipes vary greatly. Some are calorie-dense, while others are calorie-deficient. Certain foods have regulated salt and phosphorus levels, whereas others do not.

As mentioned in “When to Switch to Senior Dog Food? (Vet Answer)” by BestForPets (bestforpets.org), many senior dogs may not require dog food prepared particularly for elderly dogs. For the most part, a high-quality, well-balanced adult dog food will suffice.

But, dogs with age-related health issues may benefit most from a senior dog diet of any form. As producers make senior dog food, they frequently include arthritis, heart ailments, and renal issues.

Yet, senior dog food varies so significantly that it is essential to check nutritional labels. For instance, the caloric content of various foods varies greatly.

If your senior dog is gaining weight, you should not use a formula that implies all older dogs lose weight. This may exacerbate their weight gain.
