Parasites And Diseases


Tick born disease. Can also be transmitted via blood transfusion. Symptoms vary widely, but most frequently are weight loss and lethargy.

     Dog World, 7/1995, page 38, "Ehrlichiosis: a tick-borne menace."


Internal fungal infection more common in the hunting and sporting breeds. Typically, active spoors are inhaled from the soil and the lungs become the conduit for this fungus. Mastiffs being a large breed with a large lung capacity the earliest sign of "Blasto" (coughing, conjestion) often goes noticed. Once inside the body, the internal heat makes an ideal breeding ground for the fungus.

Early detection is the key. Enlarged or inflamed joints or organs, lesions or enlarged lymph nodes, and loss of appetite. In males (usually intact) it first shows up with all the symptoms of a prostate infection (low grade fever, tender slighty swollen prostate gland) so it is easily mis-diagnosed. All of these signs can of course be symptoms of other diseases, but blood tests and/or fungal titers can be done for diagnostic purposes. Chest x-rays are also key diagnostic tools.

This is a very expensive disease (especially for large breed dogs, because medicine doses are based on body weight) with a cost of $1200 a month to treat, without including vet care. Diagnosed in the early stages it has an 80% recovery rate in most healthy dogs. The treatment is also very lengthy (sometimes up to 5 months).

Parasitic protozoa which can cause severe diarrhea. The latest remedies in dogs are albendazole and fenbendazole (both are wormers). Note that albendazole is not recommended for pregnant animals. One article suggests that 100% of kennel dogs, 50% of pups and 10% of well-cared for dogs carry giardia. It does point out that while people get giardia it is a different giardia and that it is unlikely that people can get giardia from their pets but caution is advised.

The following are recommendations from the July 1995 Cornell Animal Health Newsletter for eliminating giardia from kennels:

     - treat all non-pregnant dogs with fenbendazole for 5 days
     - disinfect kennel areas, etc., with quaternary ammonium disinfectants
       which are effective in inactivating giardia cysts (takes about a minute
       at room temperatures)
     - bath dogs with shampoo to remove all fecal matter, rinse with water
     - rinse dogs with quaternary ammonium disinfectants, then water
     - allow kennels to dry thoroughly for several days
     - retreat with fenbendazole for 5 days
     - treat any new dogs with fenbendazole for 5 days even if they test
       negative for giardia because it is so hard to detect in fecal tests

Transmitted by eating an affected animal such as a flea, mouse, etc.

Symptoms can include loose and/or bloody stools. Transmitted by swallowing grass or dirt in an infected area.
