Understand Your Senior Dog's Nutritional Needs

As dogs age, their nutritional needs shift. You can't feed your senior dog the same diet you once fed him as a puppy.

Older dogs are less active but still require essential nutrients to support body functions, muscle tone, and a healthy immune system. It’s not just about feeding them more or less; it's about giving the right kind of food with specific nutrients tailored for senior dogs.


Provide your senior pup with a balanced diet of high-quality protein to meet their changing nutritional needs.

High protein diets provide amino acids needed for maintaining lean body mass, antibody production for effective immune responses, and cellular repair mechanisms which are vital in aged animals who may experience injury or disease more frequently than younger ones.

Protein quality is important and is recommended to come from animal protein sources.

The American Kennel Club suggests that proteins should be highly digestible and among the first ingredients listed on the bag or can of higher protein dog food because older dogs have decreased metabolic rates.


Fat adds flavour making meals appealing but remember – moderation is key. Fat content must be controlled since seniors tend to gain weight easily due to lower energy requirements.

Not all fats are bad though - Omega fatty acids can be beneficial in moderation. Omega-6 fatty acids promote skin health while Omega-3 helps reduce inflammation associated with arthritis common amongst aging pets.

Vitamins and Minerals

Vitamin E acts as an antioxidant supporting immune function whereas B vitamins help prevent kidney disease prevalent in elderly pooches.

Micronutrients like calcium aid bone health, potassium fights heart disease and phosphorus is crucial for energy metabolism.

But it’s not just about quantity; absorption also matters. Hence, foods with highly bioavailable minerals should be preferred.


Ian's Tip: 

It's not just about giving your older dog less food, but the right kind. They need a diet packed with high-quality protein and low in fat, alongside just-right amounts of crucial nutrients.

Choose a High-Quality Food

Your senior dog needs top-quality food. It's not just about filling their belly, but choosing a diet that supports their health as they age. 

But how do you choose the best food to guarantee your dog healthy senior years?

Finding Quality Ingredients

Look at the ingredient list on the pack - it should be filled with recognisable foods rather than hard-to-pronounce chemicals.

The first thing listed on any dog food label should be a quality source of protein – chicken or beef are good options here. Steer clear from anything vague like 'meat derivatives' or 'animal by-products'. 

It is usually best to buy food from pet stores, not grocery stores. Grocery store brands are usually full of cheap fillers that can be difficult to digest.

Balanced Diet is Key

A balanced diet isn't just about protein though; consider carbohydrates for energy and fibre to keep your dog regular.

Make sure there are plenty of veggies included too. Treat your dog by occasionally adding green beans, carrots or sweet potato to their dinner.

Senior Dog Foods

Purchasing foods designed especially for senior dogs helps ensure they are getting the right nutrients for this life stage.

Quality senior foods should be high in antioxidants, omega-3s, protein and low in fat.

Choose a High-Quality Food

Wet vs. Dry Food

When deciding whether to buy wet or dry dog food, know that both types have their advantages and can be beneficial for older dogs depending on their specific needs.

Wet Food

Wet food, usually purchased in cans or pouches, is easy to chew for older dogs that are missing teeth.

Most dogs also prefer the taste and texture of wet food. A diet that your dog enjoys is more likely to be eaten regularly, helping them stay healthy and vibrant.

However, canned food is usually higher in fat. It can also stick to your dog's teeth, causing dental disease.

Dry Food

Dry kibble is usually lower in fat and helps clean your pet’s teeth as they chew.

However, some older dogs may struggle with hard kibble due to missing teeth or reduced jaw strength.

Mixing It Up

No need to stick solely with one or the other. Many pet parents find that mixing wet and dry food gives their senior dogs the best of both worlds – taste from wet food and dental benefits from kibble.

This approach also allows for adjusting ratios as needed. For example, if your dog is gaining weight, you can lower the amount of wet food but keep the same amount of dry food.

Ian's Tip: 

Choosing high-quality food for your senior dog isn't rocket science: look out for real ingredients, and ensure there's plenty of protein and fibre, plus antioxidants and omega-3s to support the ageing process.

Monitor Calorie Intake

A key part of caring for a senior dog involves watching their calorie intake.

Elderly canines usually aren't as energetic as when they were in their heyday. This change in lifestyle can lead to weight gain if not managed properly.

Unlike younger dogs who can burn off excess calories with seemingly endless energy, senior dogs don't have that luxury.

To keep your elderly pooch healthy and happy, it’s important you make sure they're eating the right amount of food each day – not too much and certainly not too little.

Vets suggest counting your pet’s caloric intake is a critical step towards successful weight loss.

When your vet recommends how much to feed your dog, they will consider your dog's breed and size. Small breed dogs tend to eat less than large breed dogs.

Tips to Monitor Calorie Intake

  • Use a measuring cup or scale to ensure consistent serving sizes.
  • Limited use of treats. If used, make sure to account for them in their daily caloric count.
  • Avoid giving table scraps – they often contain hidden calories and aren’t formulated for dogs' nutritional needs.

Feed Smaller Meals More Frequently

Caring for an elderly canine can be a challenge, but we can assist them in staying content and healthy by making minor alterations to their diet. One such change is feeding smaller meals more frequently throughout the day.

Digestive Benefits

This method of feeding helps manage hunger better than serving one large meal. This practice not only keeps your pet's energy levels steady throughout the day but also eases digestion. 

Serving up numerous smaller feeds allows a dog's stomach some respite instead of being overwhelmed with a large quantity at once. This approach aids in reducing bloating and discomfort which are common issues amongst older dogs.

According to the American Kennel Club, this eating style has been shown to support better absorption of nutrients as well — an important factor considering that nutrient absorption can decline in senior dogs.

Maintaining Healthy Weight

Beyond aiding digestion, frequent small meals can help maintain weight control too – essential for our less active seniors. A constant intake ensures they're not overeating while keeping their metabolism working efficiently.

A study published in the Journal of the American Veterinary Medical Association highlights that regular feedings prevent sudden spikes or crashes in blood sugar levels - another win towards managing weight healthily.

Switching to Smaller Meals

Transitioning your senior dog to this feeding method should be a gradual process. Start by splitting their usual meal into two portions and gradually increase the frequency while reducing portion sizes.

It's key to getting good-quality, nutrient-packed meals for your elderly pup. You want each small meal to pack a punch nutritionally. For personalised advice on diet alterations for your senior dog, it's always wise to consult with a vet.

Ian's Tip: 

Help your senior dog stay healthy and happy by switching to smaller, more frequent meals. This change eases digestion, manages hunger better, and supports nutrient absorption - vital as these can decline in older dogs. It also helps maintain weight control, important for less active seniors. Always remember to consult with a vet for personalised diet advice.

Consider Supplements

Senior dogs often benefit from a bit of extra help in the form of supplements. As they age, certain functions can start to decline and that's where targeted supplementation comes into play.

Always purchase supplements designed especially for dogs, never give your dog human supplements.

Glucosamine & Chondroitin

A common supplement for older dogs is glucosamine. This nifty compound helps support joint health and can give your ageing pooch some pep back in their step. 

Think about supplementing your older pup with glucosamine as well as chondroitin; the two of them together can really help to enhance joint performance and ease arthritis pain.

Omega-3 Fatty Acids

Found abundantly in fish oils, omega-3 fatty acids are an essential nutrient that contributes not only towards luscious fur but also aids cognitive function too.

Include sardines in your dog's diet for an omega-3 boost!

Consult Your Vet First

 Always consult with your vet for a pro plan before starting any new supplement regime. Just like humans, dogs have individual dietary needs and tolerances.

Consult Your Vet First

Provide Plenty of Water

Your dog's water intake plays a vital role in keeping them healthy. It aids digestion, helps maintain body temperature, and provides joint support to ease movement.

A constant supply of fresh water is key to keeping your older mate hydrated. Ensure your dog has access to fresh, pure drinking water throughout the day. 

Check and refill their bowl frequently as some dogs may drink more due to health issues like poor kidney function.

Choosing the Right Bowl

Regular water bowls can be difficult for older dogs to bend down and drink from. This can deter them from drinking as often as they need and lead to dehydration.

All For Paw's Elevated Food Bowl is a great option to help manage an older dog's hydration. It has 3 height options to make it easier for your dog to bend down plus you can adjust the tilt to reduce neck strain.
