Complete Great Dane Feeding Guide
Expert Tips for Great Danes
Feed 3 small meals daily — bloat is the #1 killer. NEVER feed one large meal. Giant-breed puppy food until 18-24 months. No exercise 1 hour around meals. Keep at lean weight. Elevated bowls are controversial.
Practical Feeding Guidelines
Meal Frequency
Feed 2-3 measured meals per day. Avoid single large meals to reduce bloat risk.
Portion Control
Always measure portions with a kitchen scale or measuring cup. Treats should not exceed 10% of daily calories.
Hydration
Ensure fresh water is always available. A Great Dane needs approximately 72–143 oz of water daily.
Weight Monitoring
Weigh your Great Dane monthly and adjust portions accordingly. Ideal body condition means you can feel (but not see) the ribs.
