What are Tapeworms?

Tapeworms are a parasite that are found in the small intestine of dogs. The most common tapeworm found in dogs is the Dipylidium Caninum.  They are flat and segmented, white in colour and can grow up to 20cm long. They attach themselves to the dog's intestine by their hook like mouth.

How does a dog get tapeworms?

• The tapeworm cycle begins with the flea larvae eating fecal matter that contains tapeworm eggs.
   

• The eggs hatch inside the flea and become cysticercoids.
   

• A dog may then swallow a flea that contains these cysticercoids while chewing or biting at an itchy area on it's skin.
   

• Once the flea passes into the dog's intestine the flea is broken down and the cysticercoids develop into an adult tapeworm.
   

• The tapeworm attaches itself to the lining of the intestine and feeds off the nutrients.
   

• As the tapeworm matures the tail segments drops off. These segments are mobile. Each segment contains the eggs of the tapeworm. The egg packets are passed in the feces of the dog.
   

• The eggs are then ingested by the flea larvae

The most common areas that tapeworm eggs are found are in the dog's bedding and in your carpet.

Dogs can also acquire tapeworms by eating infected rodents or lizards.
