Common Causes

Stress-induced defecation can be caused by several conditions: fight-or-flight response releasing adrenaline, which speeds up gut motility; common during car rides, vet visits, thunderstorms.

What to Do at Home

While you should always consult your vet for persistent or severe symptoms, here are some immediate steps you can take.

1. Document the stool — take a photo for your vet and note the consistency, color, and frequency.
2. Monitor your dog's overall behavior, appetite, and energy level.
3. Ensure fresh water is always available to prevent dehydration.
4. Consider a bland diet (boiled chicken and rice) for 24-48 hours for mild GI upset.
5. Collect a fresh stool sample in a sealed bag if a vet visit is needed.

When to See the Vet Immediately
