Buddy the Beagle had hemorrhagic gastroenteritis (HGE) from who knows what. We could not seem to resolve his diarrhea, no matter what we tried: drugs, probiotics, etc. I gave him EmerAid Sustain HDN Canine only for a couple days, and now his poop is normal! I’m now weaning him back to real food… and he loves EmerAid Sustain HDN, too.
