Dog Diarrhea: When to Seek Emergency Veterinary Care
If your dog is experiencing diarrhea, it can be messy, stressful, and concerning. Occasional loose stool might not be alarming, but frequent or severe diarrhea can signal a deeper problem. At Five Rivers Pet Emergency Hospital in New Market, TN, our team provides 24/7 emergency and urgent care for dogs throughout Jefferson County, Morristown, Dandridge, Sevierville, and nearby East Tennessee communities. We can quickly determine the cause of your dog’s diarrhea and provide the treatment they need to recover safely.
Understanding Dog Diarrhea
Dog diarrhea is a symptom, not a disease. It often occurs when something irritates or inflames the digestive tract. While some causes are minor, others can become serious without prompt veterinary attention. Common causes include:
- Eating something inappropriate (trash, spoiled food, or foreign objects)
- Sudden diet changes or new treats
- Intestinal parasites like Giardia or roundworms
- Bacterial or viral infections
- Food allergies or sensitivities
- Inflammatory bowel disease
- Toxin ingestion (plants, medications, household chemicals)
- Organ issues affecting the liver, kidneys, or pancreas
Because it can lead to dehydration or other complications, ongoing diarrhea should always be evaluated by a veterinarian.
Dog Diarrhea: When to Worry
Pet owners across East Tennessee often ask, “When should I worry about my dog’s diarrhea?” While mild, short-term diarrhea may resolve on its own, certain signs mean your dog needs emergency care right away:
- Diarrhea lasting longer than 24 hours
- Blood or black, tarry stool
- Repeated or watery diarrhea with no improvement
- Vomiting combined with diarrhea
- Loss of appetite or refusal to drink
- Weakness, collapse, or extreme lethargy
- Signs of dehydration (dry gums, sunken eyes, panting)
- Abdominal bloating or pain
If you’re unsure, call our emergency team. We’ll help you decide whether to bring your dog in immediately.
