The mother dog then reinfects herself by ingesting the eggs when she licks her puppies clean. Intestinal parasites are also transmitted to your pets by other animals contaminating the soil. The infected animal will defecate the worm or the eggs. These eggs will then develop into a microscopic larvae. The larvae will then attach itself to your pet's paws and migrate through the body, eventually ending up in the intestine of your pet.
Tape worm is transmitted by the ingestion of fleas or the ingestion of infected rodents.
As stated earlier, treatment is doubly important because worms can be transmitted to people. These include certain species of tapeworms, roundworms, hookworms, and some other, less common types of parasites. The same larvae infecting your pet can migrate into a person and cause either a skin infection or in some cases an internal infection to the liver. This disease is called visceral larval migrans. This is why we recommend deworming all puppies, even if the fecal analysis is negative, and request regular stool examinations.
