Tapeworms or cestoda are parasites which live in the guts of host animals and spend entire generations there. These worms at maturity can reach to about 6 inches in length. They live in the intestinal tract of meat eating animals such as wolves, jackals, dogs, jackals, pigs, goats, horses, sheep and cattle.
Roundworms are bilaterally symmetrical invertebrates and are a part of phylum Nematoda. These worms have only one way digestive system and openings at both ends. Roundworms have long and slender bodies with pointed ends and have a complete digestive tract. The life cycle of roundworm starts as an egg in the feces of an animal.
The Shih Tzu was a gift from the Tibetan monks to the Chinese emperor some 1,400 years ago. During that period eunuchs were the care taker for the dogs. In China it was named as Lion Dog due to its mane resembling to that of lion and was regarded as lucky charm. Later on it gained popularity in Asia also. Lady Browning was the first one to take this dog to England and later on it became very popular.
