Medium Senior Dog Food Guide

Medium breed senior dogs (7–8+ years, 10–25 kg) face increasing joint issues, gradual metabolic slowdown, and reduced digestive efficiency. Senior food tailored to these changes supports a better quality of life.

Daily Calorie Guide by Weight

Based on RER × 1.2–1.4 for senior dogs with reduced activity. Reference food: 400 kcal/100g.

WeightDaily Calories (senior)Approx. Amount (400 kcal/100g)
10 kg~275–315 kcal/day~69–79 g
15 kg~370–425 kcal/day~93–106 g
20 kg~455–525 kcal/day~114–131 g
25 kg~545–625 kcal/day~136–156 g
These figures are estimates. Individual metabolism, health status, and activity level affect actual needs. Use body condition scoring to fine-tune.

Key Food Selection Points

  • Medium breed senior formula or senior all-breed formula
  • High-quality digestible protein for muscle mass maintenance
  • Glucosamine & chondroitin — critical at this stage
  • Omega-3 (EPA+DHA) for joint and cognitive support
  • Lower phosphorus for kidney protection
  • Regular vet bloodwork (CBC, chemistry panel) annually — more frequently if health issues are present

Frequently Asked Questions

Q. What should I look for in a medium senior dog food?

Quality animal protein as first ingredient, glucosamine and chondroitin for joints (essential for medium breeds prone to hip issues), omega-3 for inflammation reduction, lower calorie density, and lower phosphorus. Choose foods without artificial colors and synthetic preservatives.

Q. My medium senior dog is stiff in the mornings — can diet help?

Morning stiffness is common in dogs with arthritis or hip dysplasia. Glucosamine (500 mg/kg+) and omega-3 in the food may help reduce inflammation and improve joint function. Fish oil supplementation is also well-supported. For moderate to severe stiffness, consult your vet for a multi-modal pain management plan.

Q. How many calories does a medium senior dog need per day?

Approximately 70 × weight(kg)^0.75 × 1.2–1.4 kcal/day — about 15–20% less than an active adult. For a 15 kg senior, that's roughly 370–425 kcal/day. Use body condition scoring to fine-tune portions.

Q. How often should I take my senior dog to the vet?

At minimum, twice yearly for senior dogs (6-month intervals). Annual bloodwork (kidney function, liver enzymes, thyroid, CBC) helps detect age-related diseases early. More frequent visits may be needed if chronic conditions are present.
