Senior Dogs' Diet: Essential Nutrients And Foods To Include

what do older dogs need in their diet

As dogs age, their nutritional needs change. Senior dogs have different nutritional requirements, and these needs vary depending on the dog. For example, the size, breed, weight, lifestyle, health, and individual metabolism of a dog will impact its diet. It is important to consult a veterinarian to determine the best diet for your senior dog, as they can help identify any medical conditions that may require a special diet. Senior dogs are prone to developing arthritis, and there are dietary changes that can be made to slow its progression and reduce symptoms. Obesity is a common issue in older dogs, and it is important to prevent it to promote the dog's health and well-being. Lower-calorie foods with an increased nutrient-to-calorie ratio are recommended for overweight and inactive dogs. Protein is a critical nutrient for senior dogs, as it helps to maintain muscle mass. Overall, by understanding the unique nutritional needs of senior dogs and making the necessary dietary modifications, owners can support their ageing companions and ensure their health and happiness.

The importance of protein

As dogs age, their health and nutritional needs change. Senior dogs have different nutritional needs, and these needs also depend on the individual dog. While it is important to consult a veterinarian for specific advice, it is generally understood that protein is a critical nutrient for maintaining good physical health in older dogs.

Protein is necessary to build and maintain muscles, and as dogs age, they often stop synthesizing as much protein on their own, increasing the need for it in their diet. Loss of muscle mass is a major problem in older dogs, and some seniors lose so much muscle that they can no longer walk unassisted. According to Veterinarian Ernie Ward, older dogs need about 50% more protein to maintain muscle mass compared to younger dogs. Diets formulated for adult maintenance often do not have enough protein to satisfy these needs.

Protein is also important for a dog's immune health and skin and coat health. When protein is broken down, it creates amino acids that can be reassembled into the proteins a dog needs. Ten essential amino acids are needed for dogs to maintain a healthy life, and these nutrients must be supplied in their diet. Animal protein sources have the highest amounts of essential amino acids, and while dogs can be sustained on a completely plant-based protein diet, it is best to consult a veterinary nutritionist if you are considering a vegetarian or vegan diet for your dog.

While the optimal amount of protein that should be fed to senior dogs is still a topic of discussion, there is an agreement that higher protein quality is important. It is also important to note that, while high-protein food has not been shown to cause kidney disease in healthy older dogs, it is valuable to re-evaluate the protein and phosphorus levels in a dog’s diet once kidney function is compromised.

Omega-3 fatty acids

Eicosapentaenoic acid (EPA), another important omega-3 fatty acid, plays a central role in reducing inflammation and improving cardiovascular health. It is a key component in treating joint pain and improving mobility in dogs with arthritis or related mobility challenges. EPA is also found in fish oil supplements and fatty fish like sardines and anchovies.

For dogs on a vegetarian diet, flaxseed and chia seeds provide alpha-linolenic acid (ALA), which is a precursor to EPA and DHA. While ALA is not as potent as EPA and DHA, it still offers notable health benefits. It is important to note that dog food manufacturers often use meat from corn-fed animals or refined oil, which are high in omega-6 fatty acids. Therefore, it is necessary to balance the intake of omega-3 and omega-6 fatty acids in a dog's diet.

Consulting with a veterinarian is crucial to determine the appropriate dose of omega-3 fatty acids for a dog's specific weight and health needs. They can provide guidance on adding omega-3 fatty acids to a dog's diet through supplements or dietary sources like fish oil, fatty fish, or plant-based options. By incorporating omega-3 fatty acids, you can enhance your dog's overall health, vitality, and quality of life.

Calorie control

As dogs age, their dietary needs change, and their calorie intake must be controlled to maintain their health and happiness. Obesity in dogs is linked to a range of health issues, including osteoarthritis, heart disease, kidney disease, cancer, and a shorter lifespan.

A dog is generally considered a senior when it has reached half of its life expectancy, and this differs according to breed and size. Smaller breeds tend to age more slowly and are considered seniors around 10-12 years of age, while larger breeds age faster and are seniors from around 7 years old. As a dog ages, its daily energy requirements may decrease by 12-13%, so it is important to control their calorie intake to prevent obesity.

Senior dogs that are overweight can benefit from a lower-calorie diet with an increased nutrient-to-calorie ratio. This can help to minimise the loss of lean body mass and manage any health conditions that may arise, such as arthritis, heart disease, or kidney disease. It is important to note that very old dogs may need to increase their caloric intake as their body condition and weight naturally decline with advanced age.

The amount of calories needed to induce weight loss varies among individual dogs due to differences in their MER (Minimum Energy Requirements) and level of activity. MER decreases in response to caloric restriction and weight loss, so it is crucial to regularly adjust their calorie allowance to maintain ongoing weight loss. Monitoring a senior dog's weight and body condition can help identify obesity early on and manage it effectively.

It is recommended to consult a veterinarian before making any dietary changes for your senior dog. They can advise on the appropriate calorie intake and help create a diet plan that suits your dog's individual needs, taking into account their breed, size, health, metabolism, and activity level.

Veterinary diets

As dogs age, their health and nutritional needs change. Senior dogs have different nutritional needs, and these needs also depend on the dog. It is important to consult your veterinarian before making any dietary changes for your dog.

Senior dogs with arthritis or related mobility challenges may benefit from long-chain omega-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). However, high doses are necessary to see improvements. Glucosamine and chondroitin supplements can also support joint health, but it is important to use veterinary formulations.

It is important to note that nutritional needs vary for every dog, and it is recommended to consult a veterinarian to determine the best veterinary diet for your senior dog's specific needs.

Supplements

As dogs age, their health and nutritional needs change. Senior dogs have different nutritional needs, and these needs vary depending on the dog. It is important to consult a veterinarian to determine the best diet for your dog.

Senior dogs must visit the vet twice a year to detect any changes in organ functions and other internal issues. The vet can advise on any supplements your dog may need. It is important to choose supplements carefully, as they are not always well-regulated. It is best to purchase supplements from a veterinarian or another reputable source to avoid any counterfeit products.

Glucosamine and chondroitin supplements can support your dog's joints, and there are other options such as "avocado and soybean unsaponifiables" and curcumin. SAMe (S-adenosyl methionine) is good for liver health, and omega-3 and omega-6 fatty acids can be beneficial for brain function. Long-chain omega-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) may be beneficial for dogs with arthritis or related mobility challenges, but high doses are necessary to see improvement.

If your dog is still active, there is no need to decrease portions. However, if your dog is less active and starting to gain weight, you should decrease portions or switch to a lower-calorie food. Senior dog food formulations tend to be lower in calories. If your dog has lost interest in food, sardines can help pique their appetite, but these should be given in small amounts due to their high fat and sodium content.
