Why are yellow things still in my dog's poop after tapeworm meds?

Updated on September 23rd, 2025

Pet's info: Dog | Cairn Terrier | Male | unneutered | 17 lbs

My dog, 17lbs has been fighting tapeworms and I’m at my wits end. I hope you can help. They’ve now taken Praziquantel (2 34mg pills) twice (3wks apart) Every time, even right after a dose I still see little dark yellow ball like shapes in their poop. Rarely will I ever see the stereotypical white pieces that move (maybe once a month). Praziquantel is suppose to help kill pretty much all tapeworms I’ve been told, so what’s going on? I’ve attached a picture of my dogs poo. He was treated yesterday

Those yellow things don't look like the typical tapeworm. I would recommend to take the sample (containging the yellow things in question) to the vets office to have them look at it under a microscope. That will be able to show if it is eggs of the tapeworms or not. A fresh sample is best for testing. I hope things get figured out for Corky!

Are yellow dots in dog poop undigested rice or tapeworms after deworming?

It does look like this could be undigested rice. If you are giving her a broad-spectrum dewormer that kills tapeworms on a regular schedule, then it should be keeping her free of those. If you want to be sure that she is free of parasites or if these spots in her stool continue, I would recommend having a fecal exam done. Some parasites are microscopic and cannot be seen with the naked eye. Thanks for using Petco Pet Education Center, formerly Petcoach!

What are these light yellow corn-like bits in my puppy's stool?

Its hard to say what that is. Its possible that Rocco ate something (a pebble, small piece of plastic toy) and its passed out in his stool. Tape worms will sometimes look similar to what you described. I would recommend to have his stool tested for worms. If you see these objects again, put them and a sample of the stool in a baggie and have the veterinarian look at them. I'm glad Rocco is otherwise doing well. I hope this answer helps.

My dog is still sick after tapeworm treatment. What should I do?

It is not typical to have side effects a week after being treated for tapeworms so there could be something else going on. If he hasn't had a stool sample tested for parasites then you should take a sample to your vet for testing. He could have additional parasites and need a different dewormer. Continue to monitor him and if his signs continue or progress then he should be examined by a vet to determine the cause and treat. Dogs get tapeworms from eating fleas so he should be treated for fleas with a medication, like NexGard, Frontline, Bravect, etc. Hope he feels all better soon!

Unusual yellow seeds in dog poop: Are they parasites or food?

Thank you for submitting your question regarding Chaka. The objects look more like seeds to me than parasites. Could he have gotten into squash or something similar in the trash? If not, then you will want to take a sample to his veterinarian to rule out any parasites. If he is acting ill, then he should be examined by his veterinarian. I hope this information helps!

My puppy has yellow seed-like things in her poop. Is it worms?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Chica has tapeworm. Tapeworm are usually from fleas (current or previous infestation). Most general puppy dewormers do not kill tapeworm. Chica should get a dwormer that gets tapeworm, either drontal or cestex or droncit. Your boxer can not get tapeworm from those segments, she would need to have ingested a flea as well. I hope this helps and I wish Chica the very best!

My puppy's poop has tiny yellow spots after diarrhea, what is it?

Yellow specks can be worm eggs or can be related to something he may have eaten but not digested. If his stool was not checked for worms due to the diarrhea, I recommend to have it checked for parasites. Best of luck

My dog has stringy yellow poop that gets stuck. Could it be worms?

You can take a fresh stool sample to your veterinarian and have it examined. You can also get a wormer from your vet or from a pet shop. You also might want to take Iggy to the vet for a wellness exam.
