Description: This dewormer (originally branded Bayer, now manufactured under Elanco) is built around praziquantel, a single-purpose active ingredient specifically effective against the two most common tapeworm species affecting dogs. Tapeworms typically enter a dog's system when they swallow an infected flea while grooming, or when they eat rodents or other prey carrying the parasite, which is why tapeworm segments — small, rice-grain-like pieces visible around the anus or in stool — are the most common giveaway sign. The tablet can be given directly by mouth or crumbled into a small amount of food, and is approved for dogs and puppies as young as 4 weeks old. Unlike some broader-spectrum dewormers, this product targets tapeworms specifically rather than roundworms or hookworms, so owners dealing with a mixed parasite issue may need a different multi-worm product like a quad dewormer instead. Because tapeworms are so closely linked to flea exposure, treating the underlying flea problem alongside deworming is important — otherwise reinfection is likely even after a successful treatment.
