Hi calgon –
The only “large breed” 4Health formula I’m familiar with is their adult formula – I’m certain they don’t have a large breed puppy formula. I’m not sure of the calcium levels in the 4Health Large Breed adult formula – but you would not want to feed an adult formula to a growing puppy. The 4Health Large Breed adult formula is very low in protein and fat and doesn’t meet the nutrition needs of a growing puppy – at only 24% protein and 12% fat I wouldn’t even recommend feeding this to an adult dog. The calcium levels in the 4Health puppy formula are too high. The Nature’s Domain Salmon formula does have appropriate levels of calcium and I would feed comfortable recommending this for a large breed puppy.
