Brian-
Protein doesn’t effect their growth at all. Excessive dietary calcium and overnutrition(being fat) does.
I do understand that many people do not like Purina, however I feel that there is a lot of misinformation about Purina on the internet. I do not like all of Purina’s lines, but Pro Plan is a quality one. I appreciate a company that does their own independant research and contributes to our knowledge base of nutrition. I also really like the Purina is one of the leading reseachers on large breed puppy nutrition. As one of the other posters on here has said before and I always give her credit for this statement “you only have one chance to create a sound orthopedic structure”. That is why I would prefer to feed a food from a company that does feeding trials and conducts their own research.
