Medody123....just wondering how your horse is doing? Have you tried any of the suggestions? Thrush at times is not an easy fix but with persistance, you can make your horse much more comfortable.
Just a note on the apple cider vinegar. When you buy the unpasteurized one (which is what is suggested to use).......take out a cup and add it to a jug of regular apple cider vinegar. Put it away for about a month and you will see that it makes the "mother" and you now have a jug of unpasteurized ACV without the larger price.
Also......I know that people do use bleach on hooves but I would be careful of using something that could potentially damage healthy tissue but that is just my preference........not starting any issues here
