What to Do If Your Dog or Cat Has Tapeworms

Many species of tapeworms parasitize dogs and cats, and the adult worms seriously harm their health, while the larval stages often use livestock or humans as intermediate hosts, threatening both animals and people. Common species include Dipylidium caninum, Taenia spp., Echinococcus granulosus, Mesocestoides, Spirometra mansoni, and Diphyllobothrium. Infection causes intestinal inflammation, malnutrition, and in severe cases intestinal blockage, with signs like vomiting, diarrhea, weight loss, and odd behavior. Diagnosis relies on clinical signs plus fecal egg exams. Prevention means regular deworming, not feeding raw offal, and controlling fleas. Treatment uses praziquantel (5 mg/kg dogs, 2 mg/kg cats), arecoline hydrobromide, bunamidine, or fenbendazole under veterinary guidance. Because some tapeworms (like Echinococcus) also endanger human health, prompt and correct control matters.
