I would go with the prescription diet recommended by the veterinarian who is treating your dog, at least till the dog is stable. Increase activity/walks, keep their weight down.
Nutrisca Salmon and Chickpea has no chicken in it (canned and dry)
I use dry as a base and add a tablespoon of wet or something as a topper.
I also add a little water to their meals and take them out frequently to void (pee) because I have been through the bladder stone experience with one of my dogs…..I would prefer not to go there again.
I feed twice a day (measured amounts), monitor meals, separate dishes, opposite sides of the room. Anything not consumed in 20 minutes is picked up and put away till the next meal.
