Hi Tina –
Protein does not contribute to developmental disorders in large breed puppies, calcium does however. Therefore it’s not necessary to restrict protein but it is necessary to ensure that the calcium levels are controlled. I’d urge you to head over to the large breed puppy forum area. There you will find links to several articles written by veterinarians explaining appropriate nutrition for large breed puppies and also a list of appropriate 4 and 5 star foods. In order to obtain the sodium levels you will likely have to contact the companies directly though. Unfortunately most companies don’t list sodium levels on the product packaging or website.
