Historically, prenatal DNA testing done in conjunction with other prenatal testing involves some risk associated with how the testing is conducted, whether amniocentesis or CVS. These tests are often discouraged for the sole reason of seeking paternity because of the increased miscarriage risks.
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.
Tapeworms have flat, segmented bodies that can extend over 2 feet long, although many only grow to a few inches or less. Each segment contains a large number of eggs, which are released when it works its way out of its host's intestines via normal bowel movements.
