Tapeworm Infection in Dogs

Overview of Tapeworm Infection in Dogs

Tapeworm infection is an invasion and multiplication of the small intestinal tract by a parasite, most commonly, Dipylidium.

Causes of Canine Tapeworm Infections

Ingestion of an intermediate (in between) host can result in tapeworm infection. Fleas and lice are intermediate hosts for Dipylidium caninum (the most common tapeworm seen in dogs) and wild animals (rabbits) for some of the other species.

What to Watch For

• Most infected individuals are usually unaffected
• Anal irritation
• Rarely, diarrhea or intestinal obstruction

Diagnosis of Canine Tapeworm Infections

A thorough knowledge of history and clinical signs is always important and, most often, helpful in making the diagnosis. Diagnostic tests necessary to confirm a diagnosis of tapeworm infection include:

• Tapeworm segments (often referred to as “pieces of rice”) identified on the feces or around the anal area
• Fecal flotation (visualizing eggs)

Treatment of Canine Tapeworm Infections

Treatment for tapeworm infection should be aimed at both the active tapeworm load and controlling the intermediate host (usually fleas).

Any of the following anthelmintics (dewormers) can be used to treat tapeworm infections:

• Fenbendazole (Panacur®)
• Febantel (Vercom®)
• Praziquantel (Droncit®)
• Epsiprantel (Cestex®)

Home Care and Prevention

Strict flea control is very important to prevent reinfection of Dipylidium. Administer veterinary prescribed medication and be aware of reinfection with exposure to intermediate hosts.

Prevention of tapeworms involves controlling the intermediate host by treating both the affected animal and the environment.
