His stools have been very good lately. We are easing him into it because he is very sensitive to things but so far, so GREAT !! Review: We needed a top-shelf probiotic for a serious situation. This did the trick. - Our elderly dog needed a shot of systemic antibiotics, which knocked her gut flora out of whack. Our flooring was not pleased. Additionally, the shot knocked the whole dog on her backside in general. Not good. She was in very bad shape and we thought we were going to lose her. One dose of this and the diarrhea cleared up. She also rebounded dramatically, which may or may not have been a result of the probiotic. Very, very pricey but it sure seemed to do the trick when some Serious Probiotic Action was required. ## Features - SACCHAROMYCES BOULARDII + FOS PREBIOTIC: Pet probiotic powder for dogs and cats featuring low-histamine s. boulardii and fructooligosaccharides (FOS) to support digestive balance and a healthy gut microbiome.
