Depends on signs
Green poop usually means your dog ate a lot of grass. It can also come from food dyes, Giardia, or rodenticide baits dyed green or blue.
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
- Eating grass or plants
- Green food or treat dyes
- Giardia or other infections
- Rat or mouse bait (dyed green or blue)
What to do
- If your dog grazed on grass and seems normal, watch.
- If rodent bait is possible, go to an emergency vet now and bring the package.
- Call your vet if green stool lasts more than a day or two.
