Hi Danni A- It was long thought that protein affected the growth rates of large and giants breeds and could cause weight issues and rapid bone growth that lead to horrible orthopedic disorders. Since all those years ago, many nutritionists interested in large/giant breed puppy growth re-researched the subject and found that it was not protein at all in fact that was the cause, but too much or too little calcium.
That being said, so long as you not overfeeding and your dogs are maintaining an ideal weight and you are feeding a food with an as fed calcium to phosphorus ratio between 1.1:1 – 1.5:1 your pups should keep up an optimal growth pace.
If you’re ever concerned that your pups food might not be meeting these requirements, contact the company by email, ask for the MAX levels of calcium and phosphorus and use the calculator tool near the end of this article to check if the food meets your giant breeds needs for safe levels of calcium.
