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.
Canine parvovirus (CPV), is a viral disease that is highly contagious and can spread quickly to dogs that are not immune from the disease. The current strain of parvovirus (CPV2) was discovered in 1978, and within 2 years had spread all over the world. Parvovirus can affect dogs, wolves and foxes; but it cannot infect other animals and cannot be spread from dogs to humans. However, other animals and humans can pass the virus onto dogs. Parvovirus affects mainly puppies and younger dogs. (However, older dogs can catch the parvo virus as well.) Puppies between weaning and up to six months of age are the most at risk.
