2 more cents worth: Six weeks between appointments is way too long for a dog with diarrhea/intestinal issues. Antibiotics should work in a matter of days, except for maybe low dose long term therapy, but that wouldn't be tried unless a definite diagnosis had been made and no other ABs worked quicker.
I suspect too that this may be C-diff/Clostridium, which normally responds to Metronidazole. Metro is normally dosed for 1-2 weeks, but to clear Clostridium, the dog needs to take it for 3-4 weeks. Changing up on ABs with this bacteria will only make it even more resistant. |
