food allergy?

I used to feed my Eng. Bulldog nutromax with lamb dry food.  I now switched him to homemade food consisting of Chicken, brown rice, and carrots (i had been doing mixed vegetables, but now carrot slices).  He has started having eye infections and the folds around his nose seem to be getting infected and he has started getting bad acne even though i feed him using a stainless steal bowl.  I had taken him to the vet she gave me some antibiotic ointment for his eyes which i used and it seemed to clear, but the infection has seemed to come back.  I'm wondering if it's something he's eating.  I thought that chicken, brown rice and carrots were healthy choices.  Can you tell me if you think he could be allergic to one or all of those ingredients and recommend something.  
Thank you for your help

The best choice for a dog with has food allergies is a single novel protein and a hypoallergenic vegetable.  Novel proteins are something that your dog has not been exposed to before such as venison,  fish, rabbit, duck, kangaroo, buffalo, tofu, or other unusual protein source.  Brown rice can be an allergen, but chicken is a very common allergen.  Carrots,  celery, berries, sweet potatos and sweet potatos are hypoallergenic.  I would eliminate chicken and brown rice for 3 months to see if the symptoms go away.  If they don't I would have your dog allergy tested.  If they do you have your answer.  I would also add vitamins, and a probiotic supplement to your dogs protocol.
