My dog passed a long, segmented worm. What kind is it and what to do?

Updated On September 23rd, 2025

Pet's info: Dog | Pomeranian | Female | unspayed | 6 years and 1 month old | 12.5 lbs

I think I pulled out part of a worm from my Pomeranian's bottom. It's 4-5 inches long, a centimeter wide, and tapered/segmented. She wasn't eating a couple weeks ago and her coat is dull. After looking online I really could only find instances of worms that were smaller.

It sounds like it was a tapeworm. They are flat and segmented. The length depends on the segments that come out--they are offered compared to pieces of rice when individual. These worms are transmitted by the ingestion of a flea which can lead to a dull hair coat and dandruff also. It generally does not affect the appetite and cause that mucous and blood in the stool as noted in your pictures. I would be worried there is an infection of some sort and these worms are a secondary finding. You can find tapeworms medicines at the vets office or any pet store, but if the stool continues I would see a vet for further testing
