Senior Dog Nutrition: Feeding Your Aging Best Friend

As dogs age, their metabolism, digestion, and joints change—so their food should, too. In Canada, many dogs are considered “senior” around age 7 (earlier for large breeds). The goal isn’t just to add years, but to keep your best friend comfortable, lean, and energetic.

What to Feed: Key Nutrients for Older Dogs

Look for a senior formula or a well-balanced adult food adjusted for your dog’s new needs. Prioritize:

High-quality protein to protect muscle (chicken, fish, turkey). Seniors still need protein; they just need the right calories.
Moderate calories to prevent weight gain—extra pounds worsen arthritis and strain the heart.
Joint support like omega-3s (EPA/DHA from fish oil). Some foods include glucosamine/chondroitin, but evidence varies.
Digestive help with fibre (pumpkin, beet pulp) and prebiotics for steadier stools.
Dental-friendly options: kibble size/texture can help, but brushing and dental care matter most.

Tip: In Canada, choose foods that meet AAFCO or NRC nutrient profiles and buy from reputable brands with clear quality control.

How to Feed: Simple, Practical Adjustments

Switch slowly over 7–10 days to avoid GI upset.
Measure meals with a real measuring cup; recheck portions monthly based on body condition (you should feel ribs easily, not see them).
Split into 2–3 smaller meals to improve digestion and energy.
Add water or use a senior-friendly wet food to boost hydration—especially during dry Canadian winters.
Use supplements carefully: fish oil can help, but ask your vet for dosing, especially if your dog is on medications.
Watch for red flags (new picky eating, weight loss, drinking more, vomiting/diarrhea). These warrant a vet visit, not a food guess.

With the right senior dog diet—plus regular weigh-ins and vet checkups—you can support mobility, healthy digestion, and a brighter golden chapter together.
