My dog has a worm coming out of its butt. What does this mean?

Thanks for using Petco Pet Education Center, formerly Petcoach. These are tapeworms and they come from your pet ingesting a flea or eating another pets poop that has live tapeworms in it. It is contagious to other pets and people via ingestion of a live worm. You will need tapeworm specific dewormer such as Drontal or Praziquantel to rid this worm and a good flea preventative (Bravecto, Nexgard, Firstshield) is recommended. Usually tapeworms are gone after the first treatment as long as puppy doesn't get reinfected. I hope this is helpful! Take care now.

This appears to be a tapeworm proglottid. You will need to do two things: 1) worm your dog with a wormer containing praziquantel. Normal puppy or dog wormers will not kill this. 2) tapeworms are transmitted by fleas. So you will have to do flea control as well.

Thanks for using Petco Pet Education Center, formerly Petcoach! If you physically saw a long white worm come out with Suzie's poop, it is likely a roundworm. If you saw the poop a few hours later and it looked more like a small earthworm, it is more likely a fly larvae. If it's the first, check out a dewormer such as Sentry HC WormX Plus Flavored De-Wormer Chewables for Dogs, (Pet Co). Be sure to check that the product is labeled for Suzie's weight and age. Then just use as directed on the box. If it was the second, ignore it! Hope this helps and best of luck to you and Suzie!

It would be worthwhile taking a sample to your vets office to confirm exactly what species they are but if long and thin they are likely to be a roundworm species and not tapeworm (flat segments and often moving). There are many types of roundworm and your vets should be able to help you identify what you have so you can both treat and try and reduce re-occurrence

It looks like this could be a piece of a roundworm or tapeworm segment. I would recommend taking a stool sample in to be seen by a veterinarian so that the most appropriate treatment recommendations can be made. A dewormer is likely needed.

It's likely a foreign body. Bologna wrappers​ or string are common culprits. Do not pull on it. It may come out when she defacates, but she should be checked by your veterinarian to make sure it isn't wrapped up in her bowel.

I'm not sure if that's a tapeworm or a roundworm (the two most common). I recommend to have Stitch examined by the veterinarian and have his stool checked for worms. if he has one type of parasite, he may have others. Because some types of parasites can spread to humans, it's important to know the parasite status and to make sure that all pets are treated completely and correctly. I hope this helps and please feel free to post any additional questions.
