What is the difference between senior dog food and regular?

Food for senior dogs meets the nutritional needs of older dogs, which differ from those of younger dogs. Senior dogs are typically less active and have slower metabolisms, so they need fewer calories and fat. Elderly dogs also have a harder time digesting protein, so their food often has a lower protein content than regular dog food, helping to increase their quality of life.

Senior dog food may also contain additional nutrients that are beneficial for older dogs, such as;

  • - Glucosamine and chondroitin to help to support joint health.

  • - Omega-3 fatty acids that hold anti-inflammatory properties and can help improve skin and coat health.

  • - Antioxidants to help to protect cells from damage.

Choosing the healthiest food for senior dogs

This may vary depending on the dog's size, body weight, breed, health status, and activity level. 

As dogs age, some breeds, especially smaller breeds, may develop dental issues, so we would recommend soft dog food for older dogs. Look for foods with higher moisture content or specially formulated small-breed senior dog food.

Consult your veterinarian to get a recommendation for the best senior dog food for your pet, or alternatively, contact one of our customer service team to discuss. 


Other FAQ's

What age should dogs switch to senior food?

The ideal age to transition your dog to senior / mature adult dog food can vary by breed and size, but it's generally around 7 years old, while others may only show signs of ageing once they are 9 or 10 years old.


If you are determining whether or not your dog needs to be switched to senior dog food, talk to your veterinarian. 


Signs that your dog may be ready to switch to older dog food are:


  • - They are losing weight, or their muscle mass is decreasing.

  • - They are becoming less active.

  • - They have difficulty digesting food.

  • - They have developed health problems such as arthritis or kidney disease.

How much should I feed my senior dog?

Determining the right portion size for your senior dog is crucial to their well-being. 


A good rule of thumb is to start by feeding your senior dog 20-30% less food than you were feeding them when they were younger. You can then adjust the amount of food you feed them based on their weight and body condition.
