MacInnes, known as Puck, is a grinder â sailingâs equivalent of a football lineman. With their brawn, he and other grinders operate hand-powered winches that raise and trim the sails, move the boom and do other tasks that require brute strength. But MacInnes has fallen victim to legal maneuvering and technology.
A study of a cross section of puppies showed that at 6 weeks, only 25 percent of puppies vaccinated were effectively immunized. At 9 weeks, that increased to 40 percent. At 16 weeks, 60 percent responded to the vaccination, and at 18 weeks, that number increased to 95 percent.
1 Kittens can be vaccinated intranasally as early as 8 weeks of age. 2  Puppies can receive the injectable vaccine starting at 6 to 8 weeks of age, followed by a booster between 10 and 12 weeks of age. For adult dogs or puppies older than 16 weeks, the intranasal vaccine can be given once, and the injectable vaccine should be given twice, two to four weeks apart.
