Hi, I looked on the dog food ratings and the Diamond puppy food is rated at a 1 Star, so is not a very good food, you want to choose a food that is rated a 4 Star or better. Examples of these foods are Wellness, Blue Buffalo, Fromm's, GoNatural, Orijen, Artemis, and there are lots more. Go to the Home Page and on he right hand side there is a list of topics, click on Dog food and Nutrition. Then click on Dog food Ratings. The first ingredients in your dog food is chicken, chicken meal, and ground rice and chicken fat, there also are a lot of preservatives and chemicals listed, which are not good for any dog. His allergy symptoms are most likely caused by his food, and he would benefit from a food change, that is chicken, grain, potato, and preservative free ingredients. You want to do a slow transition over two weeks, so he doesn't get a upset tummy, and it can take up to a month before you see any changes or improvements in symptoms as it can take this long before the old food leaves his system.
