I have heard that some of these high protein diets cant be fed to large breed puppies. Why?
Research has shown that large breed puppies should not be fed a diet that is over 1.3 1.5% Calcium or they run a significant risk of developing bone abnormalities. Many of the high protein diets on the market today are well in excess of 1.5% Calcium. We do not recommend any large breed puppies be fed our CORE dog diets, or any of the other high protein diets on the market today. In fact, we would conservatively say that puppies in general should not feed higher protein diets that exceed 1.5% Calcium. Again, this is why we feature a maintenance claim and promote the diet for dogs over 1 year in age.
