Have you had him to the vet to be checked? When my dog was itchy, I took her to the vet and he did a skin scraping on one of the itchy spots to check for mange. The skin scraping didn’t show any signs of mites. Even then she was still treated for Sarcoptic mange to rule that out because the mites can rarely be seen under the microscope. I treated her with Revoluiton and still saw no difference. So it was probably not Sarcoptic mange. Then you have to look at environmental allergies and food allergies.
The one thing that stands out is that he started getting itchy again when you added the Acana Lamb & Apple. If it is the old formula (I don’t think the new one is available for purchase yet) it is grain inclusive. So it could possibly be due to the grains. One way to find out if he is sensitive to one type of food, you could do an elimination diet. I personally have not done this, but others on here have. So they will be more helpful with that.
As you will find out that some types of foods are better than others. For example, canned is better than kibble. Homemade raw is better than canned and so on… You can check out Dr. Karen Becker’s rankings at http://healthypets.mercola.com/sites/healthypets/archive/2010/07/21/13-pet-foods-ranked-from-great-to-disastrous.aspx
