I know this is an old thread, but I was wondering if anyone has any further thoughts about puppy vs. ALS food? I'm having trouble getting my 3 to eat their proper "adult" & "puppy" food. The nutritional analysis of food I am currently feeding is (ingredients are very similar, same brand):   
PUPPY- 
Crude Protein (% min.)	29.0 
Crude Fat (% min.)	18.0 
Crude Fiber (% max.)	3.5 
Moisture (% max.)	10.0    
ADULT- 
Crude Protein (% min.)	22.0 
Crude Fat (% min.)	16.0 
Crude Fiber (% max.)	3.5 
Moisture (% max.)	10.0   
But I was considering 2 brands of ALS food with a protein content of 38% or 29%. Do Yorkies need that much protein? Is an adult food supplemented with some extra protein okay for a puppy? Or would a puppy food be okay for a young adult/teenager? After some research, I noticed that there really isn't a huge difference between puppy & adult foods. Is it all just a marketing ploy?
