I don’t know too much…but I read an article once of someone who added activated charcoal and chlorophyll to fix bad breath. I personally haven’t tried it myself (my dogs get kinda smelly breath too, especially after their raw eggs, so I got into the habit of regular brushing/water additives/gel/etc.). I definitely understand not wanting to risk a food switch again. Hope you find something that works!
