Shih Tzu owners often ask how much to feed their dog each day. Adult Shih Tzus typically weigh between 4 and 10 kg, though individual metabolism, activity, and health status all influence true calorie needs. This Shih Tzu feeding calculator uses veterinary RER and MER formulas to estimate daily calories and food portions based on your dog's current weight, body condition, activity level, and life stage. Whether your Shih Tzu is a growing youngster, active adult, or senior companion, portion guidance should be adjusted as weight and energy change. Use the results alongside regular body condition checks and your veterinarian's advice—especially if your Shih Tzu has breed-related health considerations or is on a weight-management plan.

Shih Tzu Feeding Tips
Weigh your Shih Tzu monthly and adjust portions if body condition drifts from ideal.
Split daily calories into two measured meals to support steady energy and digestion.
Choose a complete diet appropriate for your Shih Tzu's life stage (puppy/kitten, adult, or senior).
Track treats and table scraps—they can add 10–30% of daily calories for many Shih Tzus.
Increase portions gradually during growth or high activity; decrease slowly for weight loss.
Small Shih Tzus have higher metabolic rates per kg—small errors in portion size matter more.
Health Notes
Typical adult Shih Tzu weight: 4–10 kg (small dog).
Recalculate portions after significant weight change, spay/neuter, or activity shifts.
