As dogs age, their metabolism, digestion, and joints change—so their food should too. Smart senior dog nutrition can support healthy weight, mobility, and energy, helping your aging best friend feel their best through the golden years.

What Changes in Senior Dog Nutrition?

Most dogs are considered “senior” around 7–10 years, depending on size (large breeds often age faster). Common shifts include lower calorie needs, reduced muscle mass, and higher sensitivity to rich foods. In Canada’s cold months, some seniors move less, making weight gain more likely.

Calories: Choose a senior formula or reduce portions if your dog is gaining weight.
Protein: Aim for high-quality, digestible protein to help maintain lean muscle.
Fibre: Moderate fibre supports digestion and can help with weight management.

How to Choose the Best Food (and When to Add Supplements)

Look for a complete diet that meets AAFCO/NRC standards and lists a named protein (like chicken or salmon) first. If your dog has kidney or heart disease, don’t “guess”—ask your vet about a therapeutic diet.

Joint support: Consider omega-3s (fish oil) for inflammation; many Canadian vets recommend it for arthritis support.
Dental-friendly options: Kibble size/texture or approved dental diets may help if chewing is difficult.
Wet + dry combo: Adding wet food can boost hydration—useful for seniors who don’t drink much.
Treats: Keep treats to <10% of daily calories; swap in carrots or blueberries (in small amounts).

Tip: Transition foods slowly over 7–10 days to prevent stomach upset.

Simple Feeding Checklist for Older Dogs

Feed 2 smaller meals daily to support digestion and steadier energy.
Track weight monthly and adjust portions by 5–10% as needed.
Watch for red flags: vomiting, diarrhea, picky eating, or rapid weight change—book a vet check.

With the right senior dog food, smart portions, and targeted support, you can keep your older dog comfortable and thriving. When in doubt, your veterinarian is the best partner for a personalized plan.
