FidoSpore™ is the first pet probiotic clinically proven to heal leaky gut and support digestive health in dogs and cats.
This powerful formula contains three special bacteria strains that survive your pet's stomach acid and work directly in their gut where they're needed most.
Clinical studies showed FidoSpore™ dramatically reduced inflammation, diarrhea, and vomiting in pets within just 30 days.
The special "spore-forming" bacteria create a protective shell that helps them reach your pet's intestines alive, unlike regular probiotics that often get destroyed by stomach acid.
