When your dog has diarrhea, it is natural to worry. Diarrhea in dogs is one of the most common reasons for vet visits and can range from a mild upset to a sign of serious illness.
What causes diarrhea in dogs?
Common triggers include sudden diet changes, eating something unusual, food intolerance, stress, intestinal parasites, infections and certain medications.
- Dietary indiscretion (eating garbage or table scraps)
- Parasites such as worms or giardia
- Viral or bacterial infections
- Chronic conditions such as inflammatory bowel disease
My dog has diarrhea but is acting fine
A bright, active dog with a single mild episode may only need close monitoring. Ensure fresh water is available, watch appetite and energy, and call your vet if diarrhea continues for more than a day or two.
What can I give my dog for diarrhea?
Do not give human anti-diarrheal medicine without veterinary advice, because some are unsafe for dogs. Your vet may recommend a short period of a bland, easily digestible diet or a prescription product after examining your dog.
Blood in dog stool or poop
Blood in dog stool, or a dog pooping blood, should always be taken seriously. Black, tarry stool or heavy bleeding needs urgent veterinary attention.
When to call your vet immediately
- Blood in the stool, repeated vomiting or severe lethargy
- Pale gums, dehydration or abdominal pain
- Puppies, seniors or dogs with existing health conditions
