Bought this for our senior dog who has developed skin issues, yeast infections that reoccur. The vet had him on antibiotics for 5 weeks, which I don't like and followed the medicated Vetra Seb shampoo with a lime sulfur dip twice a week until the bottles were empty. The infection cleared up but is coming back one flaky bald patch at a time. Trying to keep the infection at bay. Using shampoos but also need something to work from the inside out. Read a great deal of information about dog skin yeast infections and what other dog owners have had to go through to help there dogs. This item is just one that keep popping up to work. We're on our first jar. It's too soon to tell yet, whether this works or not for him, and I will update review when I do see results. I hope it works. This is just one item I purchased including medicated shampoos. It doesn’t seem to bother my dog to use this at all and he doesn't seem bothered by the taste either. Just add one scoop per one cup of dog food and that's it. It's a fine pink powder which is nearly odorless.
