I was just reading about Purina's "Forti Flora. and it leaves me wondering how safe it actually is.
It has ONE so-called probiotic, which is Enterococcus faecium.
This bacteria has some negative findings.
Here is the first line from the abstract :
"The characteristics of Enterococcus faecium have led to concern regarding the safety of probiotics that contain this bacterium. The results of an in vitro filter mating assay indicate that a probiotic E. faecium strain might be a potential recipient of vancomycin resistance genes."
Here's the actual link to the whole article :

So, IMO, if your dog takes Forti Flora, poops, licks it's butt then gives you a kiss, you might be asking for trouble.
