Tapeworm infestations are commonly found in dogs worldwide. While mild or moderate infestations do not significantly impact health, heavy infestations can cause issues like weakness and vomiting. Tapeworms are flat, segmented worms that attach to the intestinal wall. Dogs become infected by ingesting fleas carrying tapeworm larvae. Heavy infestations can lead to complications like anemia or intestinal blockages. Tapeworms are generally treated with oral or topical praziquantel, which dissolves the worms in the intestine. Preventing fleas and regularly deworming dogs can help prevent tapeworm infections.
