Any time you have screaming diarrhea, fever, antibiotic usage, you should use probiotics. That said, Fortiflora is not one of the best, it’s just readily available. You might want to go to a health food store and get the one with the most different strains. If you need to keep your pet on it long term then I would suggest you order from Mercola. They have a great probiotic. Swansons has a pretty good human one for a lot less.
