Ok, so the main difference b/w the two kibbles is exclusively the complete proteins in totw, versus the incomplete vegetable proteins in Hills. As far as proteins go, egg white is considered the easiest complete protein to digest and is considered the benchmark by which all other proteins are graded, in consideration of digestion.
Then comes : (2) muscle meats, (3) organ meats, (4) milk and cheese, (5) and fish, and then the incomplete proteins follow: soy, rice , oats , wheat , yeast , and corn! Which is amazing as your dog is doing fine on the corn, the low man on the list, go figure?!

Let's see, egg is the main complete protein in Hills, and he is digesting that fine along with the corn. So maybe if you keep him on a non-meat complete protein he might do just as well.
There are several kibbles out that he might enjoy as well as he does the Hills.
There is something else you might want to consider supplementing into his diet. There is a product called,"NaturVet; Enzymes and Probiotics", it essentially helps the digestive tract maintain its healthy bacterial flora, while adding enzymes that assist in the breakdown of food. This might be helpful for your pup considering he is having digestive issues with the protein, and throwing up undigested food. I found mine at the local pet store, but I have included a link to where you can buy it online. My little girl had issues of this nature, mucus-y diarrhea and vomiting intermittently during her life. So, I started her on yogurt and then switched to this as well to help her, and it truly has.
I have also include links to various other high quality low protein kibbles that might work for your pup.
If you are planning on switching, I would do it extra slowly considering he already has digestive issues. Plus if he seems to do fine on any one of these and you feel that you would like to add in more proteins, then you can always just add in a soft cooked egg white to whatever kibble he is on. That would give him the added protein, without the problems associated with trying to digest a complete meat protein.

Well, this is all I can think of for now, but I will keep looking for other options for you.
Hope this helps you out!

Thanks so much, I truly appreciate your help. I did try yogurt with him on a couple of different occasions but he refused it. I will definitly buy the enzyme. I will look into the other foods you have listed. I am waiting on samples from wellness simple solutions.
Agian, thanks so much!!
