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.
July 4, 2009. Puppies are irresistible but vulnerable. They depend on you to replace that vulnerability with a vaccination shield. Your puppy should get his first shots between 5 to 7 weeks old, concluding with a few more rounds by 16 weeks old. Your veterinarian should assess your pup's health prior to getting vaccinated, as illness can interfere with a vaccine's ability to work.
