The case against the use of metronidazole in canine canine diarrhoea gains traction
I’ve been uneasy for a while about the drugs we often use in acute vomiting/diarrhoea dogs. Metronidazole being high on the list. Recent evidence supports the contention that metronidazole isn’t necessary. And that’s not taking into account any possible longer-term adverse effects on gut microbiota.

A Randomized Double Blinded Placebo-Controlled Clinical Trial of a Probiotic or Metronidazole for Acute Canine Diarrhea
Justin Shmalberg1*, Christina Montalbano1, Giada Morelli2 and Gareth J. Buckley3
‘Dogs presenting with acute diarrhea achieved acceptable fecal consistency after 3.5 ± 2.2 days when receiving probiotic, 4.6 ± 2.4 days with oral metronidazole, and 4.8 ± 2.9 days with placebo; statistically significant differences were not identified between treatment groups‘
The same is true for the other, similar, recent study:
