This guide covers how the 2019 AAHA Canine Life Stage Guidelines define a senior dog, what to check on a dog food label, and a few senior-labeled dry foods sold in the US. It is general information, not veterinary advice. Your veterinarian is the right person to decide what your dog should eat.

When Is a Dog Considered a Senior?

The 2019 AAHA Canine Life Stage Guidelines define the senior stage as "the last 25% of estimated lifespan through end of life." Estimated lifespan is breed and size dependent, so the age at which a dog becomes a senior differs from dog to dog. The same guidelines state that "the senior dog should have at least semiannual exams."

How to Choose a Senior Dog Food

1. Check the Nutritional Adequacy Statement

According to the FDA, a food whose nutritional adequacy statement says "complete and balanced" is intended to be fed as a pet's sole diet. To make that claim, the food must either meet an AAFCO nutrient profile or pass an AAFCO-procedure feeding trial. AAFCO has two dog profiles: one for growth and reproduction and one for adult maintenance. Treats, snacks, and supplements are typically not intended to be a pet's sole diet.

2. Ask Who Formulates the Food

The WSAVA Global Nutrition Committee suggests asking the manufacturer whether it employs a nutritionist, and lists appropriate qualifications as a PhD in animal nutrition or board certification by the American College of Veterinary Nutrition (ACVN) or the European College of Veterinary Comparative Nutrition (ECVCN). It also suggests asking who formulates the diet.

3. Talk to Your Veterinarian

The 2019 AAHA guidelines say nutritional assessment should be part of every visit to the veterinary practice, and note that senior dogs often have other conditions that should be considered when doing it. If your dog has a health condition, follow your veterinarian's guidance on what and how much to feed.

Frequently Asked Questions

At what age is a dog considered a senior?

The 2019 AAHA Canine Life Stage Guidelines define the senior stage as the last 25% of a dog's estimated lifespan through end of life. Estimated lifespan depends on breed and size, so there is no single age that applies to every dog.

When should I switch my dog to senior food?

There is no single answer for every dog. The 2019 AAHA guidelines say nutritional assessment should be part of every veterinary visit and that senior dogs should have at least semiannual exams. Ask your veterinarian whether and when a diet change makes sense for your dog.

Is grain-free senior dog food better?

In July 2018 the FDA began investigating reports of dilated cardiomyopathy (DCM) in dogs eating certain pet foods, many of them labeled grain-free. The FDA has not reached a final conclusion and has said it does not intend to release further public updates until there is meaningful new scientific information. Talk to your veterinarian if you have questions about your dog's diet.
