I posted this reply in another thread, but then I thought it would be best to open a new discussion topic with it. So here it is:
Allow me to clarify this: the right combinations of calcium and phosphorus are the ones that promote a puppy's bone structure development (or grow). The wrong ratios of calcium and phosphorus can have serious negative effects on a puppy, whether be excess or lack of these two minerals. Therefore, as long as you get a puppy formulation from a reputable dog food manufacturer, chances are it will contain the desired ratios of calcium and phosphorus for the appropriate development of the growing puppy.
In the other hand, protein builds tissue, muscle, and it is absolutely vital for the healthy development of a growing puppy, who demands a higher nutrition level than an adult dog. However, excesses of protein can overburden the dog's kidneys, so again the right amount of it is of paramount importance.
Having said all of the above, I want to emphasize, again, that most SUPER PREMIUM PUPPY FORMULATIONS have the necessary ratios of high quality protein, carbs, fats, vitamins and minerals for an adequate nutrition, as demanded by a growing puppy. The problem lies on the fact that "generic puppy foods" not only are of low quality, but have undesired ratios of sources of nutrition, thus affecting the puppy's positive development.
In my opinion, this new tendency to feed growing puppies with adult foods is wrong. Puppies have different nutrition needs than adults. Just spend a little more money on your beloved dog and buy the finest food you can get! That will make the whole difference in the world
