As the “mom” to three toy dogs, I do not believe that small breeds need a special diet unless, of course, they are suffering my some sort of illness that would require omitting or adding certain ingredients. At 8 months of age a toy breed no longer needs to be on puppy food. An All Life Stages food would better meet their needs at this point in time. My dogs weigh 5 lbs, 6 lbs, and 7 lbs.
As Marie stated, large breed puppies require less calcium in their diets to avert the quick growth in a large breed that could possibly lead to bone issues once grown. Large breed puppies have specific needs that must be met. I also, like Marie, have never had a large breed dog but I know others that do. My dogs have all been toy dogs with the exception of one dog that I had many years ago (Tibetan Terrier).
