Good Evening, and thanks for the question:
I’m sorry to hear about Emma’s recurring condition. What is most concerning to me is the fact that at first Emma seemed to begin improving, and now the stool consistency has gone back to its original, watery state (have you noticed any blood in her stool?). This could be indicative that there is something more going on than what your Veterinarian initially suspected.
I am assuming that since she is on Flagyl, that she has been on the medication for five days. Ordinarily, one should begin to have seen a marked improvement by this time, if the Flagyl is the proper medication for the suspected condition. Has your Vet prescribed any type of particular diet while Emma is being treated? Do you know what the initial cause of the diarrhea was? Is Emma prone to eating table scraps, finding old food or garbage outside, etc.? Has she ever had this type of problem previously? Is she of normal weight?
Often, dogs can be notorious for eating fatty or other “people” type foods which can often cause problems such as pancreatitis or irritable bowel, to name a few.
It is my recommendation that as Emma’s condition is not improving, that you contact her Veterinarian and inform her/him of the situation. If she were my patient, I would want to re-check her and perhaps perform some additional diagnostics, starting with some basic bloodwork and a repeat of the fecal sample (if there is an internal parasite problem involved, it may not always show up with just one sample). I’m sure your Vet would appreciate knowing that Emma is not responding.
Please feel free to ask any further questions, and I do hope that Emma gets back to her healthy self soon!
All the best,
-Dan C., DVM.
