Best Dog Food For Seniors

Looking for the best senior dog food for your aging pup? As our beloved pups age, we need to think even harder about the food we put inside them. Just like us humans, his body will slowly start changing and getting weaker, and might not be able to tolerate the food he once loved. With his aging bones and weakening immune system, he will also need different nutrients and vitamins.

This is also an important stage in his life because the food that we feed him may well increase his lifespan, and the longer we can keep our pets healthy and with us, the better. In this guide, we will explore what it means to be a senior dog, what health issues he might start to face, or already face, and what key nutrients and vitamins he will need as part of his daily diet.

From here we have looked at the best foods available on the market for your senior dog, and we have put together our list of the very best natural dry kibble. Nutrition is the easiest way to keep your beloved dog healthy and if you stick to our list of recommendations below, you won’t go wrong!

Entering Their Senior Years

Some dogs, like humans, age a long time before they go grey, and some go grey long before they age. According to the American Veterinary Medical Association dogs do not age at a rate of 7 human years for each dog year, so this is an old wives’ tale! But it is generally thought that when a dog reaches the age of 7 he is a senior dog, after all that is 44 to 56 years in human years, depending on his size.

Smaller dogs tend to live a lot longer than large or extra-large dogs, therefore the life stages of a smaller dog are extended across a longer time frame, and the life stages of a larger dog are equally compacted into a shorter time frame. If he is a smaller breed, being 20 pounds or less, then he might be considered a senior dog at around the age of 8. If he is a large or extra-large breed, with a large breed being 51 pounds and upwards, then he is considered to be a senior dog at the ages of 5 to 6.

However, there are a lot of other factors to consider besides his age, if he is still really fit and active, then he may not need senior dog food just yet.  Or if he is really slowing down and appears stiff and lethargic, then he may need senior dog food slightly earlier. Lethargy is a big factor to consider for any dog age, and while it is normal for an aging dog to be less active, it is not common for him to become lethargic to the point where he doesn’t want to move at all.  If your senior sits in the corner staring at a wall or seems generally confused, then get him to the Veterinarian, as this may signal a more serious health issue.

Senior Dog Nutrition

Older Senior Dog
Your dog’s nutritional needs will change as they enter their senior years.

Health concerns are one of the main factors to consider when choosing the right food for your senior dog, this will be heavily influenced by his breed, as the Chihuahua’s food needs for their health are much different to that of an English Mastiff, so of course you need to look at his specific breed’s health concerns before you make a decision.

Generally, however, there are common age-related factors to consider when looking at senior dogs as a whole population. The main things to think about when it comes to feeding your senior dog are:

Weight Management

This is the biggest concern for senior dogs when it comes to their nutrition. As they get older, they will become less energetic over time, and eventually only really waking from a snooze for a toilet break or a cuddle from his master, therefore he will need less and less calories. If you were to feed him the same food as when he was running around for an hour a day, then he will become very porky very quickly. And not only that, but his metabolic rate decreases as he ages, so he is much more likely to become obese as he gets older if his diet is not controlled. Therefore, senior dogs should be fed senior formulas that are age and calorie appropriate.

Mobility Management

Senior dogs will inevitably slow down, and this is not solely due to less energy. Many older dogs will suffer from arthritis, joint pain or joint stiffness. Therefore, most senior formula will have extra nutrients such as Glucosamine and Chondroitin which helps support healthy bones and joints. In addition to this, another big factor to think about when it comes to his slowing mobility is his weight, because if he is carrying extra weight then this is going to have a massive impact on his bones and joints too, so be sure to manage his weight if he is struggling with his mobility.

Digestive Management

If there is something not quite right with his digestive system then you will soon know about it! Your dog will either have diarrhea or constipation, foul-smelling gas (more than normal!), become nauseous, or he might not want to eat anything at all. If your pup is struggling with any of this then it is best to get him to the Veterinarian straight away, but also try feeding him a high fiber diet too. Fibers, such as sweet potatoes, green beans and legumes, while they cannot be digested by his body, help his digestive system in so many ways, so check out our guide to feeding him a high fiber diet. Senior formulas take this into account, and therefore they tend to have extra fibrous content, with added probiotics that introduce friendly bacteria to his gut.

While many of his health concerns cannot be prevented or resolved simply by nutrition (although some can!), his symptoms can be alleviated somewhat with the right food and diet. Therefore, it is so important to listen and look at your pup, assess what he needs, and make the right nutritional choices for him.

We love the cost-effectiveness of this particular senior food.  If you can’t afford to go natural, this is a great alternative. We actually prefer Iams over Pedigree and several other budget brands.

Foods For Seniors With Dietary Needs

Senior Dog Food For Overweight Pups
If your senior is overweight, or has a sensitive stomach, there are several options to help.

Controlling his weight will not only help to reduce the risk of cardiovascular diseases, but it will also decrease the pressure on his aging bones and joints. In order for your senior dog to lose weight, he either needs to become more active and burn that energy off, or eat a lot less calories, and it is more likely to be the latter option with senior dogs. So, if he is struggling with his weight and joints, or even if his body shape has changed and you can’t see his defined waist anymore, then switch him to a specific weight management kibble with less fat and calories.

We love that this recipe is specifically formulated with overweight seniors in mind. Be sure to follow the package guidelines closely and continue his exercise routine as directed by the Veterinarian. You also need to ensure that you don’t feed him any unhealthy snacks, and carrots and apple slices are a good alternative if you can convince him!

We love that this food helps with both sensitive stomachs and sensitive skin.  Purina Pro has different formulas for many different needs, and this formula is no different.

Final Thoughts

Our beloved senior friends have blessed our lives for the last 7 years or so, and now that they are aging and have specific digestive and health needs, we should put the extra effort into giving him the age specific nutrients that his body needs and craves.

His nutritional needs will vary dependent on his age, breed and previous overall health, and now that he might face more health issues than he previously has done, you should ensure that you take him to his Veterinarian check ups regularly. If he has any particular requirements over and above his age, then your Veterinarian will be able to guide you with specific advice.

But if his health issues are just age related then sticking to the above recommended senior dry kibble will not only provide him with the extra nutrients that he needs to be happy and healthy, but you might just keep him with you for a little longer.
