Usually mild
A small amount of mucus can be normal; it lubricates the colon. Larger amounts, often with jelly-like stool, usually mean inflammation of the large intestine (colitis).
See a vet now if you notice:
- Black, tarry stool or lots of blood
- Vomiting as well, or not eating
- Lethargy, weakness or pale gums
- A puppy, senior or dog with health problems
- Possible toxin exposure (rat bait, medicines)
Possible causes
- Colitis from stress, diet change or eating garbage
- Parasites such as whipworms or Giardia
- Food intolerance
- Inflammatory bowel disease
What to do
- If your dog is otherwise well, feed a bland diet for 1-2 days.
- Call your vet if mucus lasts more than a couple of days, or there is blood, vomiting or lethargy.
- Bring a fresh sample for a parasite test.
