All of my huskies seem to have somewhat sensitive stomachs, but with Nebo it's a bit ridiculous. It will only take one bite of something that doesn't agree with him to have really bad diarrhea/sometimes puking episode...often he'll act really ill for the rest of the day too. I took him to the vet for this multiple times, had blood tests, x-rays, etc. and nothing was ever found. I found he does much better on lamb or venison based food, I used to feed him a chicken based food and it was way worse. He will still periodically get these episodes (came home to one last week it was pretty awful) sometimes he'll go a few months and be fine and sometimes he'll have problems twice in a week. Usually I can trace it to something he ate but sometimes all I thought he had was dog food so I'm not sure.

Personally I don't think Science diet has very good ingredients, especially for the price. Most of their formulas contain corn and by-products which are ingredients I would want to avoid. I've had him on multiple foods over the years (he's almost 10) and he's had the same problems with all of them (just worse with chicken based foods). When Nebo gets ill I don't feed him anything until the next day to give his stomach a chance to settle down. Usually that's all it takes and he's completely fine after. I have given him pepcid AC tablets as well which help some and also plain canned pumpkin (not the kind with any spices) is good to help with the diarrhea.
