Another thought you may want to consider is that it’s not so much the dog food as it is the water. I feed high quality 5 star foods and raw and have never had the problem. I did though have the problem when I gave them regular tap water. A groomer friend of mine years ago suggested I switch to filtered water and immediately did the trick. To this day they drink filtered water and we’ve not had the problem again. It has to do with the ph in the water they drink. Hope this gives you another avenue to consider.
