Yes, my breeder (of a Greater Swiss Mountain Dog)...does not suggest feeding puppy food even after 8 weeks. Since Swissies bones grow at such a rapid pace...they suggest just feeding adult food...although in the same quanities that you would if it were puppy food (puppies get more quanity than an adult dog, depending on their weight at a certain month). Dale being a 31 lb puppy at 16 weeks old, would get more than a 7 lb. toy poodle puppy at 16 weeks (which is obvious) Large breed dogs grow up healthier if they grow at a slower pace...

I am also doing part raw diet, so Dale also gets added vitamins each day...a 1/4 of a centrum and 1 vit. C.

Smaller breed dogs, i would think, could stay on puppy food longer.
