This is a wonderful home remedy, which I discovered on this site. I take it everyday and haven't gotten sick, not even a cold, but I am posting to help pet owners whose dogs get acid reflux. My 11-yr-old Golden mix had a gurgling stomach frequently. I have been giving him a capful of ACV w/his meal and the gurgling has ceased. If I ever hear his stomach churning a bit, I give him a droper-full and it goes away within the hour. This stuff is great!
