My puppy has white worms despite deworming. How do I get rid of them?

Updated On September 23rd, 2025

Pet's info: Dog | Pit Bull Terrier | Male | unneutered | 3 months and 4 days old

My dog is about 12 weeks old or so, and every 2 weeks since getting him we have been giving him a worming treatment called Sentry HC WormX DS Liquid Wormer for dogs and puppies. Every 2 weeks by the time I'm supposed to treat him again the worms are already coming out of him. We usually notice after he gets out of bed these little white or sometimes pink worms and little yellowish-tan flecks on his bed or coming out of him. What kind of worms are these and how can I get rid of them?

The worms you describe sound like Tapeworms and these come from fleas. These worms are not treated by the product you have been giving him. Instead he needs Praziquantel (Drontal) to successfully treat these worms or a similar product that is labeled for tapeworms. You may be able to find something similar to this at your local pet store, but you vet definitely carries this int he clinic. You should also treat Thor with a monthly flea preventative to avoid re-infection, because pets get tapeworms by ingesting an infected flea.
