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.
Rabies Shots Are Essential. Rabies shots are one of the vaccines you will need to get your new puppy. These shots can be given to puppies that are 16 weeks of age. You will also need to get a vaccine booster when your puppy is a year old. Additional boosters need to be given every three years after the first two Rabies vaccines.
