Nutrition Guide: What nutrients does a senior dog need?

It is true that the best dog food for older dogs may cost well over $50, while another bag of the same size might cost less than $20. The reason for the astronomical difference in dog food prices has to do with the quality of ingredients.

To sell their dog food cheaply, some dog food manufacturers have no qualms about loading the kibble with filler: wheat, corn, and meat and vegetable byproducts. In some cases the ingredients (especially the “meat” ingredients) are unrecognizable.

To truly understand the quality differences between dog foods, let’s closely examine beneficial and harmful ingredients.

Good ingredients for senior dogs

  • Alpha Lipoic Acid: a powerful antioxidant that fights cancer, supports a healthy metabolism, and improves eye and brain function.
  • Other antioxidants: help your senior dog avoid cancer.
  • Glucosamine and Chondroitin: support joints so that your senior dog can continue to effortlessly glide across your backyard, with a smile of course.
  • Digestive enzymes and Probiotics: senior dogs may have a more sensitive tummy than their younger peers. Digestive enzymes and probiotics ensure healthy digestion and regular elimination. Specific enzymes include protease, which breaks down protein; amylase which digests carbs; lipase which breaks down fat; and cellulase which digests fiber.
  • L-Carnitine: this amino acid prevents unhealthy weight gain. It is a surefire ingredient to maintain your dog’s youthful physique.
  • L-lysine and Taurine: amino acids to keep muscles and bones healthy and strong.
  • Healthy fats and oils: healthy fats and oils help regulate metabolism so that your senior dog will not become overweight. They also keep her coat shiny!
  • Whole grains loaded with fiber: the fiber in whole grains feed the probiotics (healthy bacteria) and smooth the digestive process.
  • Whole animal products (preferably raised hormone and antibiotic free, free-range): in contrast to animal byproducts, whole animal products have the right nutritional composition to keep your senior dog healthy, strong, and energetic.
  • Essential vitamins and minerals: these boost immune function.

Harmful ingredients to avoid in senior dog food

  • Fillers like wheat and corn: these have little nutritional benefit and can actually block the absorption of nutrients.
  • Unidentifiable meat and veggie by-products: far from being innocent bystanders, these actively work to create imbalance in your dog’s digestive system.
  • Corn syrup: this is a fancy name for sugar. It can cause diabetes and obesity.
  • Chemicals: dogs are particularly sensitive to chemicals and synthetic ingredients. These can cause cancer.

How to compare wet and dry food

A note of caution: If your dog prefers wet dog food, pay extra attention to her oral hygiene, as it tends to worsen without proper care on a wet food diet.

When you see that a majority of the canned dog food is moisture, you may wonder if it contains the nutrition your senior dog needs. It is difficult to compare wet dog foods to dry dog foods with the variable moisture content.

But a simple dry matter basis calculation will allow you to easily compare to ensure that your dog is getting optimal nutrition. To calculate protein dry matter, take the percentage of protein divided by the percentage of dry matter (100% - moisture content). Then multiply by 100, and you have the dry matter protein content.
