Food Bowl

My Now my dog will only eat from my hand and not the meal what should I do?
I have a new puppy and what used to eating this type triangular puppy food, real one thing or another, but wouldnt eat much. Just before he decided to change the food they got sick, and we took her to the vet, and vet told us that given a little rice and chicken, until she was all better. She improved quickly, and then they even ate some dry dog food. After that she got better we decided to gradually change the dog food. So we put a lot of triangles and a couple of rounds that I think are (IAMS). She wouldnt eat either. As a matter of fact that the placing on the floor picked up and start playing, liked to play with the round. So I finally picked it up and put it in my hand so he could eat. Now my dog will only eat from my hand and not the meal what should I do? I would just like to mention the dog food is Royal Canin and MEI
That hunger and eat from his bowl ….. but of course, do so gradually so you do not believe that is neglected.
