Fortiflora is a probiotic that aims to maintain the "good" gut bacteria that is part of the normal intestinal flora. The "good" bacteria can be killed during antibiotic therapy, which can result in diarrhea. The Fortiflora website makes claims about supporting overall immune health, but to my knowledge, maintaining an appropriate bacterial balance in the gut is the main objective. All of that said, Fortiflora can absolutely be helpful during antibiotic therapy, but be sure to put it on Duck's food between his doses of medication rather than simultaneously to allow for maximum efficacy. I hope that all goes well!
