Best Dog Food for Older Dogs

When it comes to nutrition, dogs are just like people – their needs change depending on their age and individual health. As dogs age, they can develop problems with their weight, digestion, and teeth. Many dogs tend to slow down and become less active as they age. They need food with lower calories to fight obesity and the additional health problems that it can cause. Older dogs also tend to become constipated easily so their food needs a more balanced diet. Gum and oral diseases can make eating painful. The best dog food for older dogs is specially formulated to address those common health problems that are prevalent in senior dogs.

When is a Dog Considered Old?

There is no set age for a dog to be considered a senior. The age category of a dog depends on the dog’s breed and his or her overall health. Smaller dogs, like terriers and toy breeds, reach adulthood quickly but then age more slowly than their large dog counterparts. A Chihuahua, for instance, is generally not considered to be a senior until he or she is 10-12 years old. Large and giant breed dogs are considered senior citizens around age 5 or 6. As a general rule, dogs can be considered seniors when they reach over half their lifespan.

Petmd offers a useful chart comparing the average life span across dog breeds.

A dog’s final age is also effected by their weight and overall health. This is especially true for mixed breed dogs whose age limits cannot be otherwise determined. Dogs under 20 pounds have an average lifespan of 10+ years. Larger dogs, 90 pounds are more, generally live only 8 years. Finally, a dog’s individual health plays a role in determining his or her lifespan. Diseases and breed-specific anomalies can alter the ranges provided above. A dog with specific health problems, like kidney disease or diabetes, requires an individualized diet provided by a veterinarian.

How can Dog Food Help Older Dogs?

There are some common ailments that can be addressed through a balanced diet specially designed for senior dogs:


With age comes a loss of energy and a propensity to pack on extra pounds. Some conditions, like arthritis and joint pain, can lead to reduced activity in older dogs. Long-term obesity can lead to heart disease and diabetes. Dog foods that are specially formulated for senior dogs are lower in calories and made with foods that create a full feeling. Dog foods low in calories and sodium are good for dogs with heart disease. If a dog has diabetes, his or her dog food should be low in calories and higher in fiber. This diabetic diet allows the dog to absorb the nutrients slowly which reduces spikes in the dog’s blood sugar. In addition to feeding their dogs a specialized dog food, owners of obese, senior dogs should practice portion control and exercise the dog regularly.

Obese dog


Senior dogs tend to have digestive problems that lead to constipation due to their decreased activity level and muscle atrophy in their gastrointestinal tract. Specialized dog food for senior dogs contains more fiber than the average dog food. An increase in fiber in a dog’s diet will help the dog have regular bowel movements. The dog foods also tend to contain a higher protein count that can maintain muscle mass the dog developed in his or her youth.

Kidney Problems

The risk of kidney disease (or renal failure) increases as a dog ages. Specialized dog food for senior dogs contains higher quality proteins which are more easily digested and utilized by the kidneys. High quality proteins include things like eggs, dairy, and poultry. Regular dog food is also very low in water which can dehydrate and stress a dog’s kidneys.

Arthritis and Joint Pain

Arthritis and joint pain is common in small and large senior dogs. The pain encourages a sedentary lifestyle which leads to obesity, heart disease, and diabetes. Dog foods that contain omega-3 fats and natural anti-inflammatory formulas can reduce the swelling and pain associated with these conditions. The less discomfort the senior dog feels, the more likely he or she is to be active. An active dog is a healthy dog.

Gum and Oral Diseases

A majority of adult and senior dogs have gum disease from a lack of oral hygiene over the course of their lifetime. Gum and oral diseases can cause chronic pain, missing teeth, lack of appetite, and even bone loss. Some dog foods are great for scrubbing and scraping the plaque off of a dog’s teeth. Specialized food can also have additives that prevent the buildup of plaque and tartar. Senior dogs, who suffer from advanced gum disease or who have already lost teeth, can benefit from dog food formulas high in moisture content which is easier for them to consume.

Lack of Appetite

Not all senior dogs suffer from obesity. A long-term lack of appetite or disinterest in food can cause weight loss and muscle atrophy. A senior dog may not be eating due to a loss of smell or difficulty in chewing due to gum or oral diseases. Dog foods made with smaller pieces, added moisture-rich nutrients, and more appealing ingredients can encourage senior dogs to eat.
