Collie owners often ask how much to feed their dog each day. Adult Collies typically weigh between 25 and 45 kg, though individual metabolism, activity, and health status all influence true calorie needs. This Collie 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 Collie 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 Collie has breed-related health considerations or is on a weight-management plan.

Collie Feeding Tips
Weigh your Collie 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 Collie's life stage (puppy/kitten, adult, or senior).
Track treats and table scraps—they can add 10–30% of daily calories for many Collies.
Increase portions gradually during growth or high activity; decrease slowly for weight loss.
Large breeds like the Collie benefit from controlled growth rates when young to support joint health.
Health Notes
Typical adult Collie weight: 25–45 kg (large dog).
Recalculate portions after significant weight change, spay/neuter, or activity shifts.
