I have two adult Yorkies and a week ago got a 8 week old Yorkie puppy. The puppy loves to eat the adult dog food and pretty much wont eat his puppy food. I am concerned he may be getting too much of something and not enough of another. To get the puppy to eat his puppy food, I have to feed my other two in a room closed off which isnt working becuase the two adults like to "free feed" eat a little here and there when they want to. I am just wondering if when the puppy eats adult food if I am causing future growth problems or whatever????
