I work in the pet industry and I cant tell you how many times I see similar situations among customers I encounter. When it comes to pet foods in this day and age I try not to point out certain foods to be “good/not good” because what works for one may not work for another. I can tell you that you want to find a diet that is lower in “carbs” when you are in need of weight management but also because you had mentioned how with certain brands you have tried you have found skin and or bowel issues. For the skin I would try to stick with a formula that is higher in Omega 6 because this will help with over all skin, coat, and help promote healthy oils your dog produces. Also a lot of time when you play around with bouncing from brand to brand it will irritate your dogs GI tract and what I have found that works with 90% of the people I recommend this to is adding 1 tbs of UNSWEETENED canned pumpkin to each of your feedings this has worked to stop the “runs” for me seance I tried it almost a year ago.
