"Many dogs show few if any symptoms of illness when they first become infected with bacteria that cause ehrlichiosis.  When dogs do become sick, they usually are weak, lethargic and depressed.  This happens because their red and white blood cells are being depressed, damaged and destroyed."^^<http://www.w3.org/2001/XMLSchema#string>
