"Senior" isn't one thing — a 7-year-old Great Dane is senior, but a 7-year-old Maltese is middle-aged. And once a dog is truly senior, the nutritional priorities shift: joint support, kidney protection, controlled calories, and cognitive-support omega-3s matter more than in adult food.
When does "senior" start?
- Toy and small breeds (under 10kg): senior from ~10 years
- Medium breeds (10–25kg): senior from ~8 years
- Large breeds (25–40kg): senior from ~7 years
- Giant breeds (40kg+): senior from ~5 years
Don't switch to senior food just because you hit the age — transition only if your dog shows one or more of: weight gain on the current food, visible joint stiffness, slower eating, dental concerns, or vet recommendation based on blood work.
What to look for
- Glucosamine + chondroitin — for joint support. Minimum 400mg/kg glucosamine for effect.
- Lower phosphorus (< 0.8% dry matter) — easier on aging kidneys.
- Moderate protein (22–26%) — maintain muscle mass without overtaxing kidneys.
- Omega-3 (EPA + DHA) — joints, cognition, coat. At least 300mg EPA+DHA per kg body weight.
- Lower calorie density — senior dogs need 10–20% fewer calories.
- Softer kibble or wet options — dental disease makes hard kibble painful for many seniors.
Our picks
Best overall: Hill's Science Diet Adult 7+ (Senior Vitality)
Clinically formulated for dogs 7+, with published peer-reviewed evidence for maintained cognitive function. Protein 20–24%, phosphorus controlled, glucosamine and chondroitin included. Size-specific formulas available. $130–180 for 7.5kg.
Best for joint issues: Royal Canin Mobility Support (or Size-specific Senior)
Royal Canin's mobility line has high glucosamine/chondroitin/green-lipped mussel. Aussie large breeds with visible stiffness see real improvement in 6–8 weeks. $170–220 for 12kg. Pairs well with a prescription joint supplement (4CYTE, Antinol).
Best value: Advance Senior All Breed
Aussie-made, moderate protein (24%), phosphorus controlled, joint support included. $80–100 for 8kg. Solid nutrition without the price tag of Hill's or Royal Canin.
Best for kidney concerns: Hill's k/d or Royal Canin Renal (prescription)
Only use these on vet advice after blood work confirms reduced kidney function. Phosphorus and protein are both controlled aggressively — harmful to a healthy dog but essential for CKD management. $160–200 for 5–7kg.
Best for weight loss in seniors: Hill's Metabolic + Mobility
Combined weight-loss and joint formula — targeted at the most common senior issue cluster (overweight + stiff). $190–230 for 7.5kg. Expect 5–8% body weight loss over 3 months on correct portion sizes.
Wet food or kibble?
For most seniors, a mix of 70% kibble + 30% wet food is the practical sweet spot. Wet food supports hydration (important for kidneys), adds palatability for dogs with reduced appetite, and is easier on sore teeth. Try Ivory Coat Senior Wet or Advance Senior Wet Pouches.
Supplements that actually help seniors
- Omega-3 fish oil — 500–1500mg EPA+DHA daily for dogs over 10kg. Joints + cognition + skin.
- 4CYTE Epiitalis Forte — prescription joint supplement, Aussie-made, strong evidence base.
- Antinol Plus — green-lipped mussel formula, effective for mild-moderate arthritis.
- SAMe / denamarin — liver support for dogs with elevated enzymes; vet-prescribed only.
Transitioning to senior food
Transition gradually over 7–10 days to avoid GI upset. Start with 25% new + 75% old, progress to 50/50, 75/25, then full new. Seniors are more sensitive to abrupt food changes than adult dogs — err slow.
