Senior Dog Nutrition: Feeding Your Aging Best Friend

As dogs age, their metabolism, digestion, and muscle mass change—so their food should, too. Smart senior dog nutrition can support healthy weight, mobility, and energy, helping your older companion stay comfortable for years.

What to Feed: Key Nutrients for Senior Dogs

Look for a complete and balanced diet that matches your dog’s new needs. In Canada, choose foods that meet AAFCO standards or equivalent feeding trials, and ask your veterinarian if your dog has medical issues (kidney disease, diabetes, dental pain) that require a therapeutic diet.

High-quality protein to maintain muscle (unless your vet recommends restriction). Meat-first ingredients and clear protein sources help.
Moderate calories to prevent weight gain as activity drops; excess weight worsens arthritis.
Omega-3s (EPA/DHA) for joints, skin, and brain support—often from fish oil.
Fibre + prebiotics to support digestion and stool quality.
Joint-support add-ons like glucosamine/chondroitin may help some dogs, but results vary—confirm appropriate dosing with your vet.

How to Feed: Practical, Actionable Tips

Small adjustments can make a big difference for aging dogs.

Switch slowly over 7–10 days to avoid GI upset.
Measure every meal with a true measuring cup or kitchen scale; reassess portions monthly.
Feed 2–3 smaller meals daily to improve comfort and steady energy.
Choose easier textures: soften kibble with warm water or try wet food if dental issues exist.
Use treats wisely: keep treats under 10% of daily calories; swap for low-cal options like small carrot coins (if tolerated).
Track changes: appetite, thirst, weight, stool, and mobility. Book a vet check twice yearly for seniors.

Bottom line: the best senior dog food is tailored to your dog’s body condition, health, and lifestyle. With measured portions, senior-friendly nutrients, and regular veterinary check-ins, you can help your aging best friend thrive.
