Diarrhea in dogs: what to do

From soft stool to watery diarrhea, commonly caused by diet indiscretion, parasites or infection.

What are the common causes?

Intestinal parasites

Home monitoring

Roundworms, hookworms, tapeworms and more — common in puppies, causing anemia and malnutrition.

Acute gastroenteritis

Monitor for 48 hours

The most common digestive problem, usually from diet indiscretion (scavenging, sudden food changes) or mild infection.

Canine parvovirus

Emergency — go now

A highly contagious viral disease attacking unvaccinated puppies, with high mortality — earlier treatment means better outcomes.

Pancreatitis

See a vet within 24 hours

Often triggered by a fatty feast (table scraps, fatty meat); Schnauzers and similar breeds are higher risk.

FAQ

Is diarrhea in dogs serious?

It depends on the combination of symptoms, how long it has lasted, and your pet's energy and appetite.Note that it can appear in problems that need prompt care, such as Canine parvovirus, Pancreatitis. Enter the full symptom combination in our symptom checker for a more specific urgency assessment.

Can I monitor at home first? What should I watch?

If energy and appetite are normal with no other signs, 24-48 hours of monitoring is reasonable. Keep notes on frequency, duration, appetite, water intake, energy and what the stool/urine looks like — vets find this very useful.

What should I prepare before the clinic?

Note when the symptom started and how it changed; bring packaging or residue if ingestion is suspected; bring vaccination and deworming records; and if possible take a video (odd gait, cough sound) — clearer than describing.
