How are canine tapeworm infections typically acquired?

• A. Directly from other infected dogs.
• B. Ingestion of infected fleas.
• C. Inhalation of spores.
• D. Drinking contaminated water.

Answer: (B)

The main idea is that canine tapeworm infections typically require an intermediate host, usually an infected flea. Dogs become infected when they swallow a flea carrying the tapeworm’s larval stage during grooming or licking at their fur. Once inside the dog, the tapeworm matures in the small intestine and sheds segments in the stool. That’s why controlling fleas is a key prevention.

Other routes don’t fit this parasite’s life cycle. Direct transfer from one dog to another isn’t how dogs acquire tapeworms, since the parasite isn’t transmitted by contact alone. Inhalation of spores relates to fungal infections, not tapeworms, and drinking contaminated water transmits other parasites like Giardia, not tapeworms.
