Just because your dog seems to be doing alright, doesn't mean its great dog food. Great dog food is food that makes dogs thrive. Look at the ingredients and you'll find lots of poor ingredients like animal by products. This food is a rip off: it is expensive and has cheap ingredients. I wonder how hard it is to convince/pay 3 vets to recomend it. Just because a food has been developed with the use of science doesn't make it good! Science isn't always correlated with good things! I can do research on making an entirely grain based food and say it's been scientificaly developed, woop de doo
