  • Calcium calibrated for large-breed skeletal growth

  • Well-regarded within the large-breed puppy category (4.7 stars across ~9,778 verified reviews)
  • Purpose-built calcium ratio rather than a generic puppy formula
  • Widely recommended for breeds prone to rapid growth
  • More expensive than a generic all-breed puppy food
