No, no, no – do not feed Royal Canin Giant Puppy just because it has a low calcium. I agree that the calcium should be lower than 1% to start but the food needs to be at least of decent quality. Royal Canin Giant Puppy has virtually no protein whatsoever and only junk fillers in the first five ingredients:
Brewers rice, chicken by-product meal, wheat gluten, corn, corn gluten meal
You need to look over the list of foods that HDM put together at the beginning of this thread. If you’re going to continue feeding kibble, after six months of age you can move your pup to Orijen. In the meantime, find the lowest calcium, grain-free (or limited) giant/large breed puppy food you can. If a company doesn’t list their maximum calcium percentage, call them and ask.
Better yet, go raw!
