There are three basic forms of parasitism: Internal organs, blood and skin. The geographical region in which you live will determine which parasites can affect your shih tzu.



Worms are a common parasitic infestation and one cause of diarrhea. The presence of diarrhea, however, does not mean a definitive diagnosis of "worms." Definite diagnosis is made by a veterinarian, under microscopic examination, of a fresh fecal or blood sample. Only a veterinarian who has made the determination of the type of parasitic infestation should prescribe medications to treat the infestation.

Chiggers affect man and dogs and are prevalent in southern U.S. Areas. Eradication if chiggers is generally best achieved by manual removal. Prevention is somewhat effective if you will limit your shih tzu to manicured grass.

Coccidiosis cause an enteritis condition of cats and dogs. Coccidiosis is most common in puppies and kittens. Symptoms are mild to severe bloody diarrhea, lethargy and weakness from dehabilitation of nutrients caused by the diarrhea, anorexia and death if not treated. Coccidiosis is seldom fatal when treated with the proper medication by the veterinarian who diagnoses the parasite in a timely manner. Coccidiosis is always present among canines. Some canines become carriers and have no symptoms themselves. Excessive stress can cause symptom producing coccidia in very young puppies and kittens that can become life threatening if not treated properly.

Fleas are most common to dogs of any breed including the shih tzu. Fleas constantly bite and can produce allergic reactions in some shih tzu or any breed of dog. A sensitive dog will scratch and chew to relieve the itch, only to produce a "hotspot" or some other type of skin dermatitis which can lead to a secondary infection.. Fleas can also act as temporary hosts in tapeworms' life cycles. A dog can acquire a tapeworm as it chews and ingest the fleas. Tapeworms can be effectively treated by your vet. The best protocol is to avoid fleas altogether. Flea control is comparatively easy through a wide selectin of products including soaps, shampoos, sprays, powders, dips, natural and herbal treatments.

Giardia is usually found around remote bodies of water. It can occur in dogs or shih tzu of any age and can be transferred to humans. Onset is usually sudden. Symptoms are diarrhea, lethargy, lack of appetite and weight loss. Diagnosis is made by fecal microscopic examination. Resolution is successful provided treatment is initiated early.

Heartworm occurs in two forms throughout the lower forty-eight states. One is harmless, the other if left untreated is deadly. The heartworm is carried by mosquito bites. Diagnosis is made through a blood test. Regular prophylactic treatment is available and highly recommended.

Hookworms are found primarily in the southern portions of the United States. Infection may also be transferred to puppies from the mother's milk. For this reason, all newborn puppies need to be regularly dewormed starting at 2 weeks of age up until at least 12 weeks of age following the recommendations and schedule of your own personal vet. There are a variety of dewormers available that completely eradicate the problem of hookworms.

Mange occurs in one of two forms: Demodex or Sarcoptes. Positive diagnosis can be made only by a veterinarian under microscopic examination of skin samples taken from an affected area. If treated early, mange can be completely cured. Treatment is usually by therapeutic shampoor or dips once a week for several weeks. Prevention of the mite infestations that can cause Sarcoptes mange is recommended. Ask your vet for appropriate mange mite medication to prevent the disease. The same mites that cause mange in dogs and shih tzu can cause ear mites and ear infections.
