A few episodes of diarrhea can be due to stress or change in the animal’s diet. Make sure that your pet continues to drink water, but withhold food for 12 to 24 hours. If the diarrhea persists for more than 24 hours, is black in color or contains visible blood, seek veterinary care immediately. If your pet is showing other signs of illness (vomiting, lethargy, weakness) do not wait 12 to 24 hours; seek veterinary care as soon as possible. Diarrhea can often be a symptom of more serious illness or disease, and can cause dehydration which can also be quite serious.
Of course, whenever your pet is showing serious signs of a health issue your first step is to contact your primary care veterinarian or an emergency veterinary hospital. If it is indicated that your pet may suffer from a serious condition, a veterinary specialist or emergency clinician is available at an ExpertVet certified hospital.
