My dog had flat white worms. What to do after starting dewormer?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 11 months and 3 days old | 48 lbs

A few days ago, we found flat white worms moving in my dogs poop. They have been in his poop only 3 times and now that he poops they are gone. Yesterday I started him on some medicine to remove any kind of worms. We dont have a lot of money to take him to the vet right and he's had all of his shots. Do you have any other suggestions?

It sounds as though you've done everything correctly by starting a dewormer after finding worms in George's stool. Some worms only shed intermittently, so it is not uncommon to only find worms once in a while. Remember that not every dewormer treats every type of worm. If the worms you found were long and flat or spaghetti-like, they may have been either roundworms or hookworms. Tapeworms tend to resemble grains of rice. Roundworms and hookworms are treated with most over the counter dewormers, including those containing pyrantel pamoate or fenbendazole. Tapeworms can be a bit trickier to kill, and are best treated with praziquantel-containing dewormers. I typically deworm twice, three weeks apart. If you notice any other issues, it may be worth taking a stool sample to George's vet to confirm that no microscopic parasites are also present. I hope that all goes well!
