I’m sure the vets on that site cannot make formula recommendations without actually examining your dog or consulting with a vet who has.
I switched my dogs to Purina ProPlan Focus Large Breed Adult Weight Management. Whew! Say that real fast. Lol!
What are you feeding now? I tried to find a kibble that had a similar analysis as what I was feeding. For example, calories, fat, and fiber. You could call or email whichever brand you choose for help choosing a formula.
I’m glad people are finding out about this and switching foods at least until the exact cause is found out. Good luck!
