My advice would be to try one, then later try the other, so if something helps, you know which one it is. Start with only a quarter or less of the recommended amount and take a week or so to get up to the full amount. Back off on the amount at anytime when you see a stool change. I haven’t tried Missing Link, but DinOvite helped me get my dog off of foods that were doing him damage and on to a good healthy homemade diet. I didn’t stick with DinOvite though. I just used it to round out my dogs diet until I learned enough to make good homemade.
