Contact your regular veterinary hospital if problem persists or worsens
- Contact your family veterinary hospital if your dog develops any of the following:
- Diarrhea that persists for more than a day (or if your dog has more than 3 bouts of diarrhea),
- Diarrhea that is bloody or black throughout.
- If you make an appointment with your veterinarian, get a sample of the diarrhea. Store in the fridge if not going to the vet right away.
