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.
Normally a human cannot get a dog virus like canine influenza or parvo. However, people can catch viruses through exposure to dog feces and the unsafe handling of sick or infected dogs. The dog virus a human can get is rabies. A bite from an infected dog is usually how the virus is transmitted. Though it is rare, a person can also get rabies if the saliva from an infected animal gets into their eyes, mouth or an open wound. When handling dogs, be aware that you can get parasites such as ring or tape worms, too.
