Dog Throwing Up Brown: Causes & What to Do

Dog Throwing Up Brown: What It Means

✓ Vet-referenced✓ Sources citedUpdated 2026-10-10

Depends on signs

Brown vomit is often just digested kibble. But dark brown vomit that looks like coffee grounds can be digested blood, and brown vomit that smells like feces can mean an intestinal blockage.

See a vet now if you notice:

Retching with nothing coming up and a swollen belly (bloat)
Blood or coffee-ground material
Vomiting with diarrhea, lethargy or belly pain
Not keeping water down, or not eating for 24 hours
Possible toxin, string or swallowed object
A puppy, senior or dog with health problems

Possible causes

Digested food (most common)
Digested blood (coffee-ground appearance)
Intestinal blockage (foul, fecal smell)
Eating feces or dirt
Chocolate (check for wrappers)

What to do

If it looks like food and your dog is otherwise normal, watch and feed small bland meals.
Call your vet now if it looks like coffee grounds or smells like feces.
If chocolate is possible, use the chocolate toxicity calculator.

Frequently asked questions

Is it normal for a dog to throw up brown?

An isolated episode in a dog that is otherwise eating, drinking and acting normally is often not serious. Repeated vomiting, or vomiting with other signs, needs a vet.

When should I worry about my dog vomiting?

See a vet if vomiting happens more than once or twice in a day, lasts more than 24 hours, contains blood, or comes with lethargy, diarrhea, belly pain or not eating. Unproductive retching with a swollen belly is an emergency.

What should I feed my dog after vomiting?

Wait a few hours, offer small amounts of water, then a small bland meal (boiled chicken and white rice). Return to the normal diet over 1-2 days if all goes well.
