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.
Your puppy will need his first rabies shot when heâs about three to four months of age, something that usually is set by your county or town, rather than your vet. Heâll need a booster again in a year, and then once every one to three years after that.our vet will determine the exact schedule, but typically these booster shots are given every two to four weeks until the pup is about 16 weeks old. The reason for the boosters is that puppies normally get some immunity from their mothers, and this natural immunity actually prevents the shots from doing him any good.
