And, a large breed puppy is considered to be a puppy until it’s reached about 80% of its adult weight. For most large breed puppies, that’s about one year, but is generally longer for giant breed puppies.

Puppies cannot regulate their calcium uptake like adult dogs do, which is why you need to feed a large / giant breed puppy a controlled level of calcium.

In addition to proper calcium, avoid over-nutrition (keep your pup lean) and over-exercising to prevent stressing growing puppy bodies.
