Feeding by Life Stage
Puppy
Giant-breed puppy formula is MANDATORY. Calcium must be controlled. Feed 3–4 times daily. Growth must be slow. Never supplement calcium. Never feed adult food to puppies.
Transition to adult food: 18–24 months
Adult
Need 2,500–4,000 kcal/day. Despite massive food volume, calorie density should be moderate. Feed 2–3 meals — NEVER one meal (bloat kills). Consider gastropexy surgery.
Senior
Saints age early — "senior" by age 5–6. Joint support critical at this size. Cardiac health monitoring. Maintain lean weight.
Dietary Considerations
Bloat prevention is literally life-saving. Gastropexy surgery highly recommended. Feed multiple meals, use slow feeders, no exercise near meals. Giant breed puppy nutrition is non-negotiable — calcium must be 1.0–1.5%.
What to Look for in a Food
Giant-breed formula, controlled calcium in puppy food, glucosamine/chondroitin, taurine/L-carnitine for heart, omega-3.
Weight Management
Should be large but not fat. Extra weight at 150+ lbs is enormous joint and cardiac stress. Feel for ribs despite thick coat.
