Senior Dog Care Guide
When Is a Dog Senior?
Senior age varies dramatically by breed size: toy breeds (under 5kg): senior at 8-9 years, geriatric 12+. Small breeds (5-10kg): senior at 9-10 years, geriatric 13+. Medium breeds (10-25kg): senior at 8-9 years, geriatric 11-12. Large breeds (25-45kg): senior at 6-7 years, geriatric 9-10. Giant breeds (45kg+): senior at 5-6 years, geriatric 7-8. Why this matters: larger breeds age faster and have shorter lifespans. A 7-year-old Great Dane is geriatric — needs senior-specific care. A 7-year-old Y
Senior Nutrition Priorities
Senior dog diet priorities: high-quality protein — 25-30% (NOT reduced as old guidance suggested). Protein needs INCREASE in seniors to combat muscle loss. Reduced phosphorus — kidney health. Joint support — added glucosamine, chondroitin, omega-3 (EPA/DHA from fish oil). Antioxidants — vitamin E, C for cognitive support. Reduced calories — typically 10-20% fewer calories than young adult dogs (metabolism slows). Fibre — for regular digestion. Dental considerations — softer food if dental diseas
Exercise for Senior Dogs
DO NOT stop exercising senior dogs — gradual gentle exercise is essential. Maintains muscle mass, joint mobility, cognitive function. Adjustments: shorter, more frequent walks. Multiple 15-20 min walks better than one 60-min walk. Soft surfaces — grass, dirt paths easier on joints than hard pavement. Hill avoidance — particularly going down (eccentric load on muscles and joints). Swimming — excellent low-impact exercise for senior dogs. Hydrotherapy pools available for older dogs with arthritis.
Health Monitoring
Senior dogs should see vet every 6 months (vs annually for younger). Annual health screen recommended: blood test panel (kidney, liver, thyroid). Urine test. Blood pressure. Dental check. Weight and body condition. Watch for: increased thirst and urination (kidney disease, diabetes). Sudden weight changes (cancer, diabetes, organ disease). Changes in appetite. Lumps and bumps (have all checked — most benign but some serious). Behavioural changes (CDS — Canine Cognitive Dysfunction — like dementi
