Since she's been on the FortiFlora, that should help her and actually may be helping which is why she's not going much. The pineapple could have irritated her tummy a bit since it's acidic, but you stopped that. Hmm, idk - I'd maybe take her back to the vet and he can give her an anti-diarrhea medicine, then (as long as he doesn't find any problems of course - you can ask for an abdominal xray to set your mind at ease) I'd probably go with a bland diet for a few days in addition to the FortiFlora. Between her original infection ,then the antibiotics, adding the digestive enzymes, then the other rx, could just take a bit of time to get her back to normal. You can also try about 1 tsp. of canned pumpkin (NO spices) to add some fiber to her diet for a few days. Let us know what the vet says
