A: Aglets, the little plastic or metal sleeves at the end of shoelaces, are near impossible to buy nowadays. Plastic aglets are generally molded directly onto the shoelace, while metal aglets need to be crimped onto the shoelace with a press that's carefully matched to both the aglet and the shoelace thickness.
Many species of Capnocytophaga bacteria live in the mouths of dogs and cats. These bacteria do not make dogs or cats sick. Rarely, Capnocytophaga can spread to people through bites, scratches, or close contact from a dog or cat and cause illness. Most people who have contact with a dog or cat do not become sick.
Rickettsial diseases, caused by organisms in the genera Ehrlichia and Anaplasma, cause mild to severe loss of platelets in dogs. Infection may include short- and longterm changes in the number of platelets and other blood cells. Ticks are the usual carriers of the infection. Infected dogs may have nosebleeds, bleeding into the bowels (resulting in black stools), bleeding of the gums, and prolonged bleeding after vaccination or surgery.
