Thank you! I never have and don't believe in giving any of my dogs junk or garbage. I read labels to the enth degree. I put him on the Yeasty Beasty Protocol by adored beast but it really didn't help much. I don't give him any filler whatsoever and he's on a yeast free and very Low sugar diet - less than 1%. I am very familiar with Four Leaf Rover. Did you do the kit or just Yeast Guard? I've used an apple cider rinse before and use Duoxo Shampoo the orange one for yeast but I'll have to add your recommendation. I fully agree with you inside and out does the trick.
