Hello and welcome to the forum. I am sure you will find alot of good information here and there is already a ton of information on food. The thing is that here like everywhere else there is alot of conflicting information. The reason is that you have to find the food that works best for YOUR DOG, and sometimes that is hard, it seems you are already seeing that.
I also went through what you are going through. I had Fiona on a food that she was doing well on and then I decided to change to other brands because of something I heard, read or someone told me they feed it and it is great. I went with Blue Buffalo, Canidea and Timberwolf and all of them gave Fiona the runs. I went back to the original food and have stayed there for 6 months. I dont add anything to it....just dry kibble and she has done great. We have solid poop's that dont happen a hundred times a day, a great hair coat and her weight is great. She eats Purina One Salmon and Rice and Sensitive Stomach and Skin.....would it work for your boy? I dont know because like before what works for one is not really that great for another. The bottom line to the dog food is that you buy the best food that you can afford to buy and maintain your dog on, from there a food is only as good as how well your dog responds to it regardless of the scores, surveys or how it works for some one else's.....
My suggestion on the Science Diet is that it has to many things that they dont need and there is probably a better food that your guy will do well on. There are plenty of foods out there that are "tested" and generally that is not why vets sell or recommend it. (Science Diet) it is because that is the one food that puts a lot of money into Vet Schools and just about the only brand you learn anything about in vet school. They generally recommend it because they dont know any better.
If there are no other health issues causing your guy to have a upset stomach (virus, worms) then my suggestion would be to try and visit some sites online and request sample bags and try them or go to a food that is shown to do well with sensitive stomach dogs....
